"True-1-Ton" Jeep TJ & JK Bolt-In Axle Assemblies

Custom axle assemblies are our specialty here at Rocksolid Performance. Unlike many of the aftermarket heavy-duty Jeep front axle offerings on the market — which often use stock TJ or JK knuckles, bearings & brakes — our "True-1-Ton" JK True-1-Ton Axles Installed high-pinion Dana 60 JK High-Pinion Dana 60 Rear Axle axles use a late-model 1-ton Ford unit bearings (1998-2004) redrilled to your bolt pattern of choice, and 1-ton brake components. The most common wheel bolt pattern is 8 x 6.5", but any pattern down to 5 x 5.5" is possible.

RockSolid Performance "True-1-Ton" axles are a bolt-in option for your 1997-2006 Jeep TJ, or 2007-up JK. JK True-1-Ton Axles Installed The JK axles utilize tone rings front & rear that allow you to retain factory ABS, traction control & speedometer functionality. We even retain the use of your stock emergency brake!
