Read my gear pattern

Installing G2 4.88's in a 8.8. Backlash is .011 but I'm thinking I need more shim on the pinion, what do you think? This is my first regear and axle swap attempt.

Add .005 may even need a little more then that but that's where I would start.

You're out to far on the pin, and you HAVE to check the pattern with the bl set right, you want to be .006 / .008 unless the ring gear itself says it wants a specific bl setting. then run the pattern

Backlash specs are not universal, depends on the axle and what the gear manufacture specifies. The 8.8 generally as a higher backlash spec, my Nitro gears had a specification of .011" to .016". I personally thought that was high and settled on .009".

The actual 8.8 acceptable specs are from 8 to 15, however I haven't set a 8.8 past 8 yet. however I did say if the ring gear has a specific bl # put on it then adjust it to that.
Also on a off-road use vehicle that is going to put load and unload issues on the gear you really don't want a bl beyond 10
