SPC Builder Ball Joints provide an excellent alternative to traditional spherical bearings or OE ball joints when constructing custom control arms. Designed with the professional/home fabricator in mind, these rebuildable and greasable ball joints offerhigh load capacity combined with massive articulation. Derived from SPC's latest generation of large truck ball joints, the Builder Ball Joint Series features a wear-compensating design with redundant sealing for years of service between rebuilds. Use the hardened, alloy steel ball stud for Toyota Tacoma, 96-02 4-Runner, 99-06 Tundra, 01-07 Sequoia, Nissan Frontier, Pathfinder, Xterra, Equator, or Ford Ranger T-6 vehicles.
