Upper Control Arm IMCA RH w/ Alum Cross Shaft

The Upper Control Arm IMCA RH w/ Alum Cross Shaft is a purpose-built suspension component engineered for IMCA-sanctioned circle track racing and competition motorsports. Designed for drivers and fabricators who demand compliance with sanctioning body specifications, this upper control arm delivers the precision geometry required for consistent handling, predictable weight transfer, and reliable lap-after-lap performance on oval tracks. Whether you're competing in street stocks, modifieds, or sport compacts, this IMCA-approved component ensures your suspension geometry meets class regulations while maintaining structural integrity under sustained racing loads.

Constructed from aluminum with a durable black powder-coat finish, the Upper Control Arm IMCA RH features an integral aluminum cross shaft that reduces unsprung weight while maintaining rigidity critical for steering response and cornering stability. The eight-inch length and right-hand (RH) orientation are engineered to IMCA specifications, ensuring proper kingpin inclination and camber geometry for your specific vehicle platform. The tubular design balances material efficiency with strength, allowing the arm to flex predictably under cornering loads without permanent deformation—a key factor in maintaining consistent lap times throughout extended heat races and feature events. The aluminum construction also resists corrosion better than mild steel alternatives, extending service life in high-moisture or salt-heavy environments.

This upper control arm is ideal for racers, fabricators, and race shops building or refreshing competition vehicles within IMCA rule packages. Installation requires proper suspension alignment and verification that all pivot points and mounting surfaces are correctly positioned before track use. The universal design accommodates a wide range of chassis configurations, but final fitment should be verified against your specific vehicle's frame and existing suspension components. For best results, pair with matched lower control arms and have your completed suspension aligned by a technician experienced in oval-track geometry to maximize tire wear and handling consistency throughout the racing season.
