ring & pinion setup specs.

July 27, 2015
it makes it much easier if pinion depth is included in kit. that gives me a starting point towards a good wear pattern and a no noise setup.most other r&p kits have this info.
Cons:
  • No Pinion Depth Specs
Yes, I recommend this product.

The tooth count on a 9" Ford 3.70 ring gear is 37-10. When performing a gear change I recommend using new ring gear bolts p/n 5502094. You may also be interested in our Ford 9" overhaul kit p/n 9190950 to complete the installation.
