OK...that last drawing gave it away!

Front differential drop designed by Doron Strassman

Objective: It's three fold. By lowering our front differential we hoped to accomplish three things.

1. Restore CV axle angle closer to the stock position.
2. To be able to re-adjust the front torsion bars for added lift while keeping the CV angles within range.
3. We hope there will enough lift available with good CV angle and enough down-travel to fit 35" (315x75-16) tires.

Full details are on my website: http://shottscruisers.smugmug.com/ga...58314#44065969

The job was pretty easy. My mechanic completed it in about 90-minutes. Everything matched up exactly like Doron had measured it out. We figured we lowered the overall height of the diff by just under one inch. The skid plate did require some spacers on a few of the holes in order to clear the newly lowered parts.

Doron sent the details of this mod to Slee Off-Road. Slee sells this mod as a kit. Information can be found here: http://www.sleeoffroad.com/products/....htm#diff_drop

I personally recommend adding the diff drop to any size lift on the 100. At the very least it improves your CV angle which increases the life of the axle and the boot.

QUESTION? Will there be enough remaining lift and down-travel to fit 35-inch tires? Doron got me this far....I think I'll experiment with the 35's and report back to Doron.
