Save Your Diff with an Upgraded Locking Gear
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 to SuperATV’s Kawasaki Teryx KRX 1000 GDP Diff Locking Gear Upgrade. It’s made out of machined chromoly steel and hardened to protect your differential and your weekend.
At Least 23% Stronger
This Kawasaki KRX 1000 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. Our testing couldn’t break one before the axles, which are much easier and cheaper to replace.
