Yokes, flanges and U-joints are under extreme stress at launch, under load and through every shift. If they’re not built to handle it, they won’t last.

Common Failure Points in Track and Drag Setups

What Makes a Fitting Race-Grade
You’ve invested in power, suspension, and tuning. Don’t hold it all together with the weakest link.
GJ Drivelines stocks and sources race-grade fittings built for drag, drift and circuit abuse. And if it doesn’t exist off the shelf, we’ll engineer the solution in-house.
Contact us to spec your driveline before it’s the part you didn’t upgrade that takes you out.
