BMR torque arm suspension kits are designed to eliminate the rear leaf springs, replacing them with a custom upper crossmember, adjustable control arms, and adjustable coilover shocks. They will provide lateral stability for acceleration and traction, and centered suspension articulation for bind-free handling. The kits feature a precision side-to-side axle positioning Watts link. The Watts link pivot is machined from 6061 billet aluminum and utilizes greasable, internally fluted Delrin bushings for a long, trouble-free life. Best of all, the Watts link is double-shear supported, unlike any other designs on the market today. Every component in the BMR torque arm suspension kits is completely adjustable. The torque arm itself provides pinion adjustability. The control arms are adjustable in length and have multiple mounting holes plotted in an arc to provide adjustment for anti-squat characteristics, giving your ride superior handling and traction. Help your street machine or track car realize its full potential with these BMR torque arm suspension kits.
