The truth is in the pattern. 🔧

Backlash. Preload. A clean contact pattern. That's where "relentless" either shows up or it doesn't.

We build our ring & pinions from 8620 alloy, heat-treated to meet or beat OEM spec, and lapped to deliver a consistent pattern after every install! ⚙️

Builders 👇 what's your go-to move for nailing the pattern on the first setup?

Can’t rebuild your current diff or make it suit your needs we have you covered

Sometimes the factory fitted diff can’t rebuilt or can’t get a ratio to suit either a engine swap or new wheels

With our full in house engineering setup we can custom make all different options to suit what is required
What makes us different is we don’t just sell something pre made and make you work around it ,when required we can make them a true drop in package where factory brakes will bolt back on and driveshaft bolt back on making the most hassle free

For example we have a early Chev pickup where we able to modify a 9” to get a ratio that would make it a much better all rounder to make it a easier and more cost efficient we were able to retain the factory brakes and driveshaft and back on the road for years to come
