The Stock Diff Is Your Weakest Link
The factory rear differential wasn't built for big power or serious terrain. When you push your YXZ, it pushes back — and the stock unit fails. This is the upgrade that removes that ceiling.

Why Upgrade
The DifferentialYour YXZ Deserves.
The stock unit was engineered for reliability at factory power levels. This was engineered for what you're actually doing with your machine.
More Power to the Ground
Engineered for performance driving, not street compliance. You get better power distribution, more consistent traction in sand, and confidence under hard acceleration that the stock unit simply cannot deliver.
Built to Last Longer Than Your Build
Billet construction and precision tolerances mean this differential outlasts the abuse. Field-tested in Glamis and competition terrain — not a test bench.
Cole Juarez Won King of the Hill With It
This is the same differential that took home the High Boost King of the Hill trophy. You are not buying a catalog part — you are buying proven race hardware.

The Engineering
