General Tech Gear Set-Up, 9"

[jeepin4x4james]

Started doing gears in my buddies rig last night. Axles are from a late 70's F150.... Going from open with 3.55's to spool in rear, Grizzly front with 5.13's.

The 9" 5.13 is a much thicker cut gear than the stock 3.55..... So much so, that I can't get the ring gear to clear the pinion bearing housing without moving the carrier so far over that the backlash is 80+ thousandths.....

How do I fix this? Clearance the pinion bearing housing? Get thin cut gears ( are these available)?

TIA

It's pretty common to have to grind the casting around the pinion's nose bearing to clear the ring gear.

I had to do this with my build.

For people pulling up this thread in the future the same applies to 14 bolts as well

Thanks,

Years ago I set up many drag guys diffs back when most R&P's were built in the good old USA. Richmond and others beveled the ring also so the only grinding was to clean up the excess casting.
