Do you want to take that Full Width Axle you have and install it into your Jeep® CJ? This Jeep S.R.S (shackle reversal system) kit is designed to work with Full Width Axles that have spring perches that measure 31-1/4" to 31-1/2" Center to Center. A shackle reversal system or "SRS" allows the front suspension to travel in a much more natural action when the spring compresses. The new front pivot brackets are fully welded, and ready to bolt into existing holes in your CJ frame.
Why install a shackle reversal system? Because it allows the front suspension to travel in a much more natural action when the spring compresses. In stock form when the front tire comes in contact with an obstruction (shackles in front of the front axle housing), the impact is partially transmitted back to the frame via the solid rear pivot point. Reversing the pivot point to a point in front of the axle, it allows the impact to be better absorbed by the spring and shackle. The result is a more natural suspension flow over the obstacle, thanks to your Jeep shackle reversal system. At higher speeds, a smoother ride and improved handling are noticeable, while less wandering and darting are some of the advantages.
All M.O.R.E. Jeep® shackle reversal systems have a very important design feature built into the new front pivot brackets. They are designed to move the front axle forward from the stock location. When the shackle is reversed to behind the front axle, it will swing rearward and the tire will move slightly aft as the suspension compresses. Pushing the wheelbase forward will help keep the tire from contacting the fender during suspension compression. This is the only correct way to design a shackle reversal system. With this in mind, the front drive shaft will have to have a longer travel slip-yoke installed (in most cases) by a professional drive line shop.
The bracketry on the shackle reversal system is manufactured from .250" thick steel, cut with CNC laser, for .004 of accuracy. All pieces of the Jeep® shackle reversal system are precision bent to exact tolerances and assembled in jigs, and then M.I.G. welded. All hardware is grade 5. Complete instructions with several pictures are included.
