Adjustable Lower Control Arms
Part# C8010
(Race only version)
To aid in the installation of our rear suspension products, mark the rear shock absorbers
(with a marker) just below the protective skirt. This will be used as a reference later.
Place the transmission in neutral and hoist the vehicle into position. While the vehicle is in the
Air support the weight of the rear axle, raising it to the marks made on the shock tubes.
Poly bushings must be inserted into the Control Arm Ends. Using the lubricant supplied in this kit,
lubricate the internal bushing surfaces of the Poly Bushings and install the steel, Bushing Sleeves.
1. Using a small screwdriver unhook the brake cable where it attaches on the brake caliper.
Slide the brake cable out of the control arm. (remove one control arm at a time so the axle
does not pivot out of position).
2. Remove the control arm.
3. The factory control arm length should be duplicated. To accomplish this place your new control arm
on top of the factory one. Place the bolts in the Rod End and bushed end of the control arm. Adjust
the Rod End in or out, until both bolts drop through the Moroso control arm and into the holes of the
Factory control arm.
Final adjustments can be made by turning the Rod End in or out. Tighten the Jam Nut.
4. There is no incorrect way to install these Control Arms But with the car in the air it is easier to
adjust the control arms with the adjustment hex (located to the front of the car. Tighten factory
retaining bolts to 129 Lb-Ft. (Ford Motor Company Workshop Manual)
NOTE: We recommend using loctite Blue on the threads of the Jam Nuts to ensure they will
not loosen up after final adjustments are made.
5. If no custom pinion angle is desired, proceed with re-installation of brake cables etc.
For custom pinion angle proceed to “Adjust Pinion Angle” below otherwise proceed to
step 7
Repeat steps 1-5 for the control arm installation of the second control arm.
8. Re-install the brake cables. NOTE: to aid in re-assembly a pry bar can be used to rotate
the brake lever while re-inserting the cable end into the slot.
Note: after installation the brake cable should rest just above the Control Arm

Adjusting Pinion Angle
Note: When changing from a stock pinion angle to custom, the wheel base of the car
will also change.
Note: When changing pinion angle use Competition Engineering Part number C8020 to aid
in ease of adjustability.
1. Make sure the rear end is loaded and at ride height.
2. Place an angle finder on the rear portion of the drive shaft and record angle.
Now place an angle finder on the pinion yoke and record angle.
3. Subtracting one angle from the other results in you pinion angle.(Example: -2
Rear end angle subtracted from 0 drive shaft angle = -2 degrees)
4. Adjust the control arm to achieve the desired angle.
Note as a starting point, most cars seem to like 1-3 degrees negative.
5. Once pinion angle has been set, tighten all bolts to 129 lb-ft and tighten Jam Nut.
We recommend using a quality thread lock such as Loctite Blue to prevent the jam nuts
from loosening.
6. Proceed to step 8.
