S&S® Cam Gear Drive Kit
S&S’s Gear Drive kit for Twin Cam® engines replaces the factory cam chain drive with inner and outer gear sets.
Decreases drag and torsional load on the camshaft bearings, and eliminates chains, tensioners and guides that will
eventually wear out over time. Because the factory chain drive has some slack inherent in its design, there are
variations in cam timing that can lead to power losses, especially when high lift cams and performance valve
springs are installed. Requires camshafts specifically designed for gear drives (sold separately). Over- and
under-size gears are available for custom fitment of gear lash if desired.

Axtell Oil Bypass Valve
This is a new product designed and developed by the Axtell Mountain Motor
team. This bypass valve consists of a precision-machined “needle and seat” that
inserts in place of the factory oil pressure relief valve located within the Twin Cam® cam
plate. With the factory OEM oiling system configuration, when oil pressure becomes
excessive, it is bypassed from the high pressure side of the feed gerotor back to the low
pressure side, “looping” the oil in the feed gerotor gears. This causes the introduction
of air into the pressurized oil (aeration) - aerated oil is foamy and spongy, and results
in lower oil pressure and volume. When this occurs, the entire oiling system if affected
- engine heat and noise builds, piston oilers shut down sooner than designed, valve
train and top end life is shortened. This system blocks the factory port back to the feed
side of the pump and directs the bypassed oil into the cam chest. The scavenge side
of the oil pump returns the excess oil to the oil tank and eliminates the oil “looping” and
its negative effects.
Cam Plate Cutaway with #620-103 Bypass Valve
Fluted Design of Needle Allows Oil Flow Through Valve
With the Axtell valve you can expect higher, more stable oil pressure at all engine rpms, longer oil life due to reduced oil shear,
lower oil and engine temperature, improved valve train control and reduced noise. Zipper’s recommends this for use with our Red
Shift® Dual Piston Cam Chain Tensioners. Fits all factory H-D® and Screamin’ Eagle® cam plates.

Zipper’s ‘99-’06 Twin Cam® Oil Bypass Shim
The TC engine features an oil pressure bypass passage within the cam support plate that is controlled by a
spring-loaded plunger. Inconsistencies in 1999-2006 spring length and passage machining can cause the
plunger to open prematurely and/or not fully close the passage, resulting in a loss of critical oil pressure and
volume at lower RPM’s. This shim assures proper spring pre-load, improving oil pressure and volume.

Introduction to Red Shift® for Sportsters®
How to Order Red Shift® Cams for Sportsters®
Red Shift Sportster® and Buell® cams can be ordered two ways. You
can provide Zipper’s your original cam gear set (A) from your engine, and
we will remove the factory stock lobes (B) and replace them with new,
hand-timed Red Shift lobes ground from 8620 steel billet (C). H-D® had
gone to great pains to tighten gear lash on pre-2000 engines, using literally
hundreds of cam gear sizes to match manufacturing differences during
engine mass production. Installing the Red Shift lobes on the factory gear
set retains this precise fitment.
If no cores are available or you do not want to wait (in-house production
time is usually 2-3 weeks), you can order your cams installed on our new
gear cores. Our cam gears feature a keyed drive to prevent gear slippage
in severe applications, and are available with the #2 drive gear in the pre2000 wide pitch design (D) or in the fine pitch used in 2000 and later
engines (E).
Performance Notes: Any camshaft above .600” of lift on factory cores will
require the press-fit #2 drive gear to be welded (F) to prevent rotation (Zipper’s
new gear cores use a keyway on the #2 drive gear (G) to prevent rotation and
do not require welding). Red Shift Sportster® cams can be timed and shipped
un-welded, giving the performance engine builder final control of
desired cam timing. This is required for any aftermarket 4-cam cases
and recommended for all-out competition engines, due to manufacturing
variations in case and component production. Early XR-style intake and
exhaust patterns can be easily adapted. Call or write with your special
requests.
The one thing that the following cam grinds have in common is that
they usually service engines that will be run hard! For these cams to
be able to deliver maximum output reliably, consideration must be given to
the entire valve train especially in the area of the lifters and valve springs.
The lifters in 5-speed XL® engines use guide pins against a flat area on
the lifter body to control lifter rotation within the bore; they are tricky to modify properly for high lift cams and are prone to rotation
in the bore. The stock lifters in ’91-’99 engines should be replaced with units that are designed for increased lift and improved cam
following such as JIMS® PowerGlide II lifters. A Zipper’s Tappet Pin kit must be used on ’L94-’99 engines. Engines that will see
RPM above 6,000 require stiff pushrods and heavier valve springs with titanium collars to reduce valve train weight and maintain
valve control. Once control is lost, performance suffers and expensive parts get beat up in a hurry. Before making your purchase,
think of the cams as only part of your valve train system. Contact us if you need help selecting the other supporting components.

Red Shift® Cams for 5 SP EV/XB/XR Sportsters®
These engines have on-center tappets (tappet centerline in line with cam shaft centerline)Most of our 5-speed XL cams require some
clearance work to swing clearly in the engine case. This can be accomplished with our cam clearance tool (#713-908) for a very
professional result. 2000 and later models require more extensive clearancing of the case and pinion bearing race. Most models will
also require rocker box clearancing for the rocker arms on the pushrod side at full lift. Must be used with adjustable pushrods.
567V2: This extremely popular grind is used in our Super
Hammer 1200 kit, produces the widest powerband available for
the 5-speed 1200 engine! Narrow TDC lift for uncomplicated
head set-up; excellent low end power and with great acceleration.
RPM to 7200+ with proper set-up. Optimum performance with
9.8+:1 compression. Case clearancing required.

5-Speed XL Tappet Pin Kit
Pre-2000 5 Speed XL engines use a tappet guide pin to control tappet rotation in
the tappet bore. In earlier engines (‘91 to around mid-94), the guide pins were fully
supported on both sides of the tappet bore by a hole drilled in the case. In later
engines, the case was machined differently; the guide pin hole was not drilled as
deep and the pin did not fully cross the tappet, contacting only a part of the flat
machined on the tappet designed to control tappet rotation. In high lift and/or high
RPM applications, the tappet can be allowed to rotate as much as 5 degrees, resulting in premature tappet
failure and cam damage. Our tappet pin kit includes 4 longer hardened pins and a drill bit to correct this problem.
The engines in question can easily be identified by studying the photo shown. If the flat area under the cover
plate is raised as shown (not recessed), you should perform this task.

For over 3 decades, Red Shift Cams have been the choice of high performance engine builders
for aftermarket H-D® applications. Master engine developer and Red Shift camshaft designer
Dick Hilferty has always been at the forefront of the most advanced designs in all forms of racing
and performance applications. Today Dick’s designs are manufactured at Zipper’s with the most
advanced engineering design processes built into every cam. Red Shift Cams will provide you with
the most advanced components for power gains and unrivaled valve train dynamics. Maintaining
valve train control should be every engine builder’s first concern when choosing a camshaft. A
lack of valve train control, or noise, simply shows a lack of dynamic sophistication and your engine
will ultimately pay the price. Zipper’s has always believed that power gains should be achieved by
improved sophistication and efficiency, not by compromising component reliability. Let Red Shift

Tappets, Lifters, and Tappet Pins
Zipper’s Oversize Tappet Guide Pins
These oversize tappet pins allow the builder to limit tappet rotation in the lifter bore; excessive
rotation allows the lifter to side-load and cause operational issues. Red Shift recommends between
.002” - .004” of clearance. Oversized pins are available in +.002” and +.006” sizes.

Hy-Lift® Johnson ‘Direct-Shot’ Performance Lifters
#472-500 Designed for use in engines with performance cams, these lifters incorporate the
Hy-Lift Johnson “direct shot” oiling system which places much needed oil directly onto the
axle, roller needle bearings and cam lobe surface. Tighter tolerance I.D. grinding makes
for a very slow leak down in performance applications that use higher spring pressures and
more RPM capability. Sold in sets of 4, Made in the U.S.A.
Hy-Lift® Johnson ‘Race Design’ Lifters
#472-510 Designed for use in high lift, high RPM applications. These lifters leak down on
the lower end of the scale, from 8 to 20 seconds. In true performance applications these
lifters will actually “bleed” down and result in an effective loss of valve lift and duration at
lower RPMs for increased torque. These are also referred to as “Variable Duration” lifters
as the engine increases in RPM the bleed down effect is reduced, resulting in more duration
and valve lift. Sold in sets of 4, Made in the U.S.A.
Feuling® HP+ Lifters
Feuling’s® HP+ lifters are drop-in performance replacements for the stock lifters. Featuring
optimized valving that improves oil flow to the top end while retaining true hydraulic operation,
these lifters run quiet and are recommended for use with stock or Feuling’s® Super Pump oil
pump. Sold in sets of 4.

USA-made Feuling® Race Series hydraulic lifters are designed to meet the needs of large lift cams
and higher spring pressures, while maintaining proper and critical oil flow to valves, springs and
rockers. These lifters are CNC machined from cold headed 1018 steel, heat treated and precision
ground; internals are held to tight tolerances and pressure tested for a slower bleed down rate.
The Feuling® Race Lifters are designed to work in conjunction with the Feuling® or other high
volume oil pumps. Available in oversized diameters – Case Savers!

S&S® tappets have optimized plungers and metering devises to better withstand pressures with
high lift cams and heavier valve springs. EV lifters incorporate a traditional axle and inner race
within the roller assembly. The larger inner bearing race permits the use of larger rollers to
increase the load carrying surface area, increasing the life of the roller in high output applications.
Available in sets of 4; EV applications can be ordered with or without S&S® Travel Limiters
installed (adjustable pushrods required).

Zipper’s Performance Pushrods
Zipper’s TC 3/8” Diameter, .145” Wall Chrome Moly Pushrods
Strongest 3/8” straight-wall adjustable chrome moly pushrods we have! Unlike other 3/8” diameter pushrods, the pushrod
and threaded adjuster section are machined from one piece of 145” thick-wall chrome moly. By not using an insert for the adjuster,
the threaded portion remains a beefy 3/8” diameter, eliminating the chronic weak spot associated with ¼” diameter inserts. The
large diameter adjustable base and locknut provide ultimate stiffness; combined with the 3/8” diameter rod, pushrod tube rubbing
is eliminated. We recommend these pushrods for use in Twin Cam® engines with stock beehive valve springs and bolt-in cams for
precise valve train control.

Set/4 Zipper’s TC 3/8” diameter, .145” wall chrome moly pushrods
Zipper’s Pro-Taper TC/XL Pushrods
There’s Power in These Pushrods! Admittedly, the weakest link in a Harley® performance
engine is the valve train stiffness, or rather the lack of it. These high performance adjustable
pushrods add much needed stiffness to the valve train. They are constructed from .095” or .165” (extreme duty) wall chromemoly that is 7/16” diameter at the bottom and middle of the pushrod, tapering to 3/8” at the top to eliminate any chance of
rubbing the covers or head. The bottom side features heavy-duty adjusters and the tops have full-radius “Mae West” tips
for smooth operation with the highest lift cams. Our testing shows consistent power gains, even with reduced valve spring
pressure. When you control pushrod deflection, the valve stays under control for maximum available power!

Zipper’s Pro-Taper EV BT Pushrods
Our Pro-Taper pushrods are also available for the professional Evolution® engine builder who
wants the stiffest adjustable pushrods available. The weakest link in an adjustable pushrod is the
adjuster itself; keeping the pushrod adjuster as short possible helps maintain the highest resistance
to deflection. For this reason we offer the Pro-Taper pushrods, sold each, in the fully collapsed
lengths listed below so you can order exactly the lengths you need to keep the adjuster extension at a
minimum, for maximum rigidity. Pushrods are chrome moly, .095” wall, 7/16” diameter at the bottom
tapering to 3/8” at the top with a full radius rocker ball tip. Adjuster thread is 5/16” x 1.250” length, 32 TPI.
