UMI Performance 64-72 A-Body Lower Control Arms- Poly/Roto-Joint

UMI's tubular lower control arms feature Roto-Joint technology for smooth and bind-free performance. The Roto-Joint design allows for 28 degrees of unrestricted movement, improving handling and ride quality over traditional rubber or polyurethane bushings. The delrin race lining the spherical ball absorbs shock and noise for a quiet operation on any street or track. These control arms include polyurethane bushings on one end and Roto-Joints on the other, providing a balance of comfort and performance. UMI's Roto-Joint technology allows for optimal suspension articulation and prevents binding, improving traction and reducing wheel hop. The hard chrome-plated spherical ball and delrin race offer durability and wear resistance for high-performance driving. The adjustable and rebuildable design ensures long-lasting performance. The spanner wrench is used for adjusting and disassembling Roto-Joints in UMI Performance products, allowing for maintenance and rebuilding as needed.
