Product Description

The Ridetech 11289102 MUSCLEbar is an adjustable rear sway-bar system engineered for 1965-1970 GM B-Body vehicles. It is designed to improve road feel, reduce body roll, and enhance cornering performance, particularly on lowered vehicles and performance-oriented suspension builds. The kit is compatible with the specified Chevrolet, Buick, Oldsmobile, and Pontiac B-Body applications.

The 1-inch solid steel bar uses precision CNC-bent tubing and provides three published rate settings of 177, 199, and 255 lb, measured 1 inch from the end of the bar. A sliding aluminum clamp allows the effective rate to be adjusted, while low-friction frame bushings and spherical Posi-Link end links promote smooth articulation and predictable suspension movement.

The kit includes mounting brackets for both 1965-1966 and 1967-1970 chassis configurations, along with the required axle brackets, U-bolts, bushings, Posi-Link components, and hardware. It is designed for rear suspension use with the compatible GM B-Body chassis and can be used with stock or Ridetech trailing arms. Proper installation requires verification of suspension and component clearances.
