7) Reverse the disassembly steps to install the WideMaxx arms. The lower arms are labeled LF - RR (Left Front - Right Rear) and RF - LR (Right Front - Left Rear) to help with proper installation. The upper arms are all identical, just flip them over for the proper orientation. The tie bars are labeled F (front) and R (rear), install accordingly.

9) With the new arms in place, you can now reinstall the steering block/caster block and rear axle carriers. The caster blocks and axle carriers are labeled R and L to indicate right and left, and the driveshaft halves are keyed to maintain correct universal-joint alignment. There are marks in the shafts to show correct alignment, but you can just rotate the female half until it slides over the male half. The shafts only fit together when properly aligned, so its goof-proof.

11) Replace the stock toe links with the WideMaxx kits longer versions. Remove the button-head screw that secures the toe link and install the new link. Note that the toe links have a different type of hollow ball in each end. The end with the taller, hourglass-shaped hollow ball is the bellcrank end.

12) The longer WideMaxx arms call for stiffer springs, which are included with the kit. The springs are blue, indicated by a spot of blue paint on each spring. Install the blue springs on the rear shocks, and replace the front springs with the springs you removed from rear shocks. A screw secures each spring perch. Remove the screw, then push up on the perch and slide it off the shaft to remove the spring. To recap:
-Replace the rear springs with the BLUE springs.
-Move the rear springs to the FRONT shocks.
-The stock front springs are not used.
