BMR 68-72 A-Body Upper Control Arms On-Car Adj. (Polyurethane) - Black Hammertone

Starting with heavy-duty 1 5/8 inch, 0.120-inch wall DOM steel tubing, these upper control arms from BMR Suspension are built to handle the demands of performance driving. They are designed for 1968-1972 GM A-body vehicles, including popular models like the Chevrolet Chevelle and Pontiac GTO, offering a significant upgrade over stock components. The stock rubber bushings tend to deflect and absorb power, which can lead to wheel hop and inconsistent launches. BMR's design addresses this directly by incorporating on-car adjustability and durable polyurethane bushings.

The center adjuster is precisely CNC-machined from chrome-moly steel and features rolled threads for exceptional strength, while the TIG-welded chrome-moly tube adapters ensure a solid connection. These arms are fitted with two-inch, greasable, 95-durometer polyurethane bushings that provide a much more responsive feel compared to the original rubber. BMR's unique internally fluted bushing design ensures that grease is retained even under heavy load, lubricating the thrust surface and keeping operation quiet and reliable over time. This well-built control arm setup is ideal for street performance, drag racing, and road racing applications, helping to transfer power more effectively to the tires and improve cornering consistency.
