The BMR Suspension Rear Suspension Kit Non-Adjustable delivers a complete upper and lower control arm solution for 1968-1972 GM A-body platforms including the Chevelle, El Camino, Monte Carlo, Cutlass, 442, Skylark, LeMans, and Pontiac muscle cars. Built at BMR's manufacturing facility near Tampa, Florida, this polyurethane-bushed kit eliminates the flex inherent in factory stamped steel arms. We stock this kit for enthusiasts restoring classic muscle or building dedicated track cars who need consistent rear suspension geometry without the complexity of adjustable setups.
BMR engineers this kit using heavy-duty DOM steel tubing throughout. The lower control arms feature 1.50-inch diameter tubing with 0.120-inch wall thickness, while the upper arms use larger 1.625-inch diameter tubing with the same wall specification. This tubular construction provides substantially greater rigidity than OE stamped arms. The greasable 95-durometer polyurethane bushings feature internal fluting that retains lubricant under heavy load, delivering longer service life than standard rubber while maintaining better articulation than solid mounts. Each bushing accepts standard grease fittings for periodic maintenance. The complete assembly weighs 17.0 pounds and installs in approximately 3-4 hours using common hand tools.
This non-adjustable configuration suits street performance builds, drag racing, and road course applications where consistent pinion angle and wheel hop elimination matter more than fine-tuning suspension geometry. The fixed design means less time adjusting and more time driving. Pair this kit with upgraded suspension bushings throughout the chassis or complement the rear end work with replacement shock absorbers. BMR backs this kit with a two-year warranty covering defects in materials and workmanship under normal use.
This kit fits 1968-1972 GM A-body vehicles including the Buick Skylark, Chevrolet Chevelle, Chevrolet El Camino, Oldsmobile 442, Oldsmobile Cutlass, Pontiac muscle cars, Pontiac LeMans, and 1970-1972 Chevrolet Monte Carlo. Verify your specific year and model before ordering.
BMR estimates installation at 3-4 hours using standard hand tools. The process involves removing factory control arms and installing the new tubular units with the included polyurethane bushings. A lift or jack stands and basic mechanical experience are recommended.
Non-adjustable arms like the RSK011R provide a fixed geometry optimized for most applications. Adjustable versions allow pinion angle changes for lowered vehicles or specific drag racing setups. The non-adjustable design offers simpler installation and consistent performance for street and general track use.
Yes, the 95-durometer polyurethane bushings are greasable and feature internal fluting to retain lubricant. BMR recommends periodic greasing to maintain smooth operation and extend bushing life. Standard grease fittings accept common chassis grease.
BMR Suspension warrants this kit against defects in material and workmanship for two years from the original purchase date. The warranty covers normal use and service. Racing applications and improper installation may affect coverage.
