Launching harder, reducing wheel hop, and adding cornering consistency to your 1964-1967 GM A-Body is easy with adjustable upper control arms from BMR's suspension. The stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMRs polyurethane, on-car adjustable tubular upper control arm for GM A-Body (UTCA044) is manufactured from heavy-duty 1 1/4 inch DOM steel tube. The center adjuster is CNC-machined from chrome-moly steel with rolled threads for the ultimate in strength and durability. This design gives you a strong control arm that greatly improves performance. BMRs rod ends offers tons of articulation for great handling, while remaining strong enough to stand up to high loads of any performance environment. These are the perfect upgrade for the enthusiast looking for max performance at an affordable price. When performance is a must, rely on BMR's suspension! BMR's suspension designed the UTCA044 to work well in street performance, drag race, and handling applications. The stock control arms flex under even light cornering loads giving you inconsistent handling characteristics. Combine this with soft bushings that have massive amounts of deflection and you're left with poor performance. The UTCA044s heavy-duty construction eliminates control arm flex, giving you much improved repeatability on the street, starting line, or in the corners. The adjustability allows you to dial in pinion angle for reduced NVH. BMRs rod ends offers tons of articulation for great handling, while remaining strong enough to stand up to high loads of any performance environment.
