Upgraded Differential Lock Gear and Shim

When your stock KRX diff fails, it’s almost always because of the powdered metal lock gear. If you don’t want the grenade in your diff to go off and force you to replace the whole thing, upgrade this diff lock gear. It’s made out of machined chromoly steel and hardened to protect your differential.

At Least 23% Stronger
This diff locking gear isn’t an OEM replacement. It’s made with a better alloy—hardened 4340 chromoly steel. And it has upgraded fingers to beef up overall strength. The result is a gear that’s at least 23% stronger than stock. 

This can be installed with the differential still in the machine. 

Includes:

Hardened Lock Gear

Shim to reduce the factory wobble in the shift fork mechanism.
