S1V4 Competition Ball Differential+1.3mm (1pr)

Includes updated parts.

REQUIRES DRIVE BONES PRR66401106 (67mm length) to use kit settings. This is due to a increased thrust bearing width.

With the diff being wider on the Bolt head side, there are a few things you can do:

1. Grind down the bolt head a little... maybe .5mm. You still need some slot left to adjust it.

2. Run the shorter drive bones which we will say is required at this point.... 67mm (we will have more around the end of Oct/Early Nov.

3. Use the lower hinge pin inserts to pull the 68mm drive bones out of the cups a bit....then offset the track width with narrower hexes.

We understand these are not great solutions, but it's the best we have at the moment.

** Also Note: If you have an issue with the diff nut bottoming before the diff doesn't slip, then you will need to shim the diff spring and nut to allow more room for the ears on the nut to travel and load the spring more. This may be due to variances in spring height.
