Description

GM 8.5" & 8.6" 10 Bolt 4.56 Nitro Ring & Pinion

Tech Note:

Nitro 8.5/8.6 gears work on both GM 8.5" and GM 8.6" Differentials.

For 8.5" use MKGM8.5

For 1999-2008 8.6" use MKGM8.6

For 2009-2014 8.6" use MKGM8.6-B

We also offer a custom Nitro ABS Reluctor Ring which eliminates crush sleeve for Caprice & Impala models (includes shims).

Nitro gears are manufactured from 8620 steel gear forgings in the same manufacturing facilities as GM, Dodge, Ford & Toyota. They are precision machined using computer controlled processes, heat treated, CNC triple-lapped and Rockwell tested for hardness. These extra steps ensure excellent fitment, ideal contact pattern and smooth, quiet operation.
