Full Width Axle Shackle Reversal System for Jeep CJ (1976-86) with 2-1/2" YJ Springs

Installing a Jeep S.R.S. (shackle reversal system) allows the front suspension to travel in a much more natural action when the spring compresses, and our full width axle kits work seamlessly in conjunction with this system. In stock form when the front tire comes in contact with an obstruction, the impact is partially transmitted back to the frame via the solid rear pivot point. By reversing the pivot point to a point in front of the axle, it allows the impact to be better absorbed by both the spring and shackle. The result is a more natural suspension flow over the obstacle. At higher speeds, a smoother ride and improved handling is noticeable, while less wandering and darting are some other advantages.

All M.O.R.E. Jeep S.R.S. have a very important design feature built into the new front pivot brackets. They move the front axle forward from the stock location. Why? 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 build a reversal system. Due to the action of this suspension movement, the front drive shaft needs to have more slip-yoke travel than stock (almost double!). With this in mind, the front drive shaft will have to have a longer travel slip-yoke installed by a professional drive line builder. Also, a stock pitman arm may need to be retained (no drop) but will vary depending on the amount of lift you have on your Jeep®.

All bracketry in our full width axle kits is manufactured from .250" thick steel, laser cut, holes laser cut or punched (not drilled), and precision bent to exact tolerances, all on CNC equipment, assembled in fixtures and pulse-welded for superior strength. No wimpy stuff here! Our full width axle kits are built to handle the abuses of gung-ho Jeepin'. All hardware is included, and complete instructions with several pictures are provided so you can install one of our full width axle kits easily or custom design your own Jeep S.R.S.
