Drivetrain upgrades are the quiet difference between a capable truck and one that gets stuck waiting for help. Lockers, gears, axles, and portal kits put the power to the ground when traction matters. Tru Automotive carries the gear that earns its place on serious builds.
Our catalog covers selectable lockers and automatic limited-slip differentials, ring and pinion sets for re-gearing after a tire size change, axle upgrades for trucks that have outgrown factory components, and portal axle kits from 74 Weld for the most committed off-road builds. Re-gearing is one of the most impactful upgrades you can do after a tire size jump, and it pays back in fuel economy and drivetrain longevity.
Drivetrain work is also one of the most precise installs on a build. Our shop sets up gears and lockers in-house and can recommend the right ratio for your tire size, transmission, and intended use. Call us before ordering if you are not sure what gear ratio matches your build.
