INSTALLATION INSTRUCTIONS
X-BRACE KIT
C3181 – MILD STEEL
C3191 – CHROME MOLY
This kit is designed to increase the strength of your chassis by eliminating side to side twist and uneven
suspension loading. Use this kit in conjunction with the rear struts found in our roll bar and roll cage kits
to create a solid racing chassis. Install the tubes so that they mount at the intersection of the main hoop
and rear strut and the adjacent end where the rear strut meets the frame.
PARTS LIST
1) 60" Tube
2) 30" Tube Braces
INSTALLATION
1. Using the 60" long tube first, place it in position diagonally so that it mounts on the intersection of the
main hoop and rear strut on the driver's side and the intersection of the rear strut and the frame on
the passenger side. Cut and notch the tube as necessary to get a good fit. If the fit is correct, Tack
weld it in place.
2. Set the two 30" top and bottom tubes in place so that they appear to be in one continuous line. The
tubes should be centered on the previously installed tube. You can make a simple alignment fixture
with a piece of scrap angle iron with a notch cut out for the intersection. Clamp the angle iron to two
tubes. This will allow you to determine if the notches need trimming and how much.
3. When all the joints fit well, tack weld the pieces in place.
4. Place secondary tack welds opposite from the primary tack welds. This will keep the tube in place
during welding.
5. Finish weld all joints, alternating from end to end to minimize warpage.
