BMR Non-Adjustable Rear Suspension Kit with Polyurethane Bushings - Black Hammertone (RSK012H) - 1968-1972 GM A-Body
Factory stamped-steel control arms and soft rubber bushings flex heavily under acceleration, absorbing valuable power and causing wheel hop instead of transferring energy cleanly to the rear tires. BMR’s RSK012H non-adjustable rear suspension kit—featuring part numbers BCA005 lower arms and UTCA004 upper arms—replaces these weak factory links with heavy-duty tubular components designed to drastically improve traction, stability, and overall vehicle handling.
Engineered for street performance, drag racing, and road course applications, the lower control arms are constructed from heavy-duty 1x3-inch, 0.120-inch wall rectangular steel tubing, while the upper control arms are built using 1.625-inch diameter DOM steel tubing to handle extreme compression loads. Loaded with high-durometer, 95-durometer greasable polyurethane bushings featuring internal flutes for continuous lubrication, this kit delivers a firm, responsive feel without sacrificing ride quality. Finished in a durable black hammertone powder coat for long-lasting corrosion protection, this 100% bolt-on kit provides professional-grade performance.
