1" BORE UNIBALL

TMR Customs 1" Chromoly Uniball

TMR Customs 1" Uniballs are engineered for high-performance suspension systems where maximum strength, articulation, and durability are required. Trusted throughout motorsports, uniballs provide greater angular misalignment, increased load capacity, and smoother suspension movement than traditional ball joints, making them a serious upgrade for race vehicles and custom fabrication projects.

Whether you're building a trophy truck, Ultra4 car, rock bouncer, prerunner, drift car, drag car, circle track car, road race car, UTV, or custom chassis, our 1" uniballs are built to withstand the extreme loads generated by aggressive driving and harsh conditions.

Each uniball features a heat-treated stainless steel housing, a heat-treated 52100 bearing steel ball, and a self-lubricating Teflon liner for smooth, low-maintenance operation. With a 90,000 lb load rating, these spherical bearings are designed for demanding suspension and chassis applications where strength and reliability matter.

Pair them with TMR Customs uniball cups, retaining rings, and fabrication components to build suspension systems capable of handling serious abuse.
