BMR Suspension RSK466H Rear Suspension Kit Non-Adjustable Black Hammertone

The BMR Suspension RSK466H is a complete non-adjustable rear suspension kit designed for 1978-1987 GM G-Body vehicles. This comprehensive kit includes non-adjustable lower control arms (TCA039), non-adjustable upper control arms (UTCA006), and control arm reinforcement braces (RB003), providing a complete solution for eliminating wheel hop, improving traction, and enhancing cornering consistency in street performance, drag race, and handling applications.

Construction and Materials:

• Lower control arms: Heavy-duty 1.50-inch diameter, 0.120-inch wall DOM steel tubing for maximum strength
• Upper control arms: 1.25-inch diameter, 0.120-inch wall DOM steel tubing built to handle compression loads
• Reinforcement braces: 1.0-inch diameter, 0.156-inch wall steel tubing that ties upper and lower frame mounts together to reduce frame deflection
• Durable black hammertone powder coat finish for long-lasting protection

Advanced Bushing Technology:

• Greasable 95-durometer polyurethane bushings provide a more solid, responsive feel compared to stock rubber bushings
• Internally fluted design keeps grease in the bushing under heavy loads
• Flutes direct grease to outer edges and thrust surfaces for efficient lubrication
• Compliant enough for comfortable street driving while firm enough for performance applications
• Quiet, reliable operation throughout the life of the bushings

Performance Benefits:

• Eliminates control arm flex for improved repeatability on the street, starting line, and corners
• Replaces weak stamped steel arms that deflect under load and absorb power
• Handles high compression loads from aggressive launches and hard acceleration
• Provides excellent articulation for superior handling characteristics
• Maintains acceptable NVH levels and ride quality for daily driving

Proudly made in the USA. Installation time is approximately 4-5 hours. All necessary hardware included.
