The legendary GM A-Body platform, encompassing classics like the Chevelle and Cutlass, offers immense potential for performance. However, the original factory rear control arms are often a weak link, especially when increasing horsepower or upgrading other suspension components. Replacing both upper and lower arms is foundational for a truly capable rear suspension.

Superior Rear End Stability & Power Transfer for Classic Muscle Cars

This set of upper and lower rear control trailing arms is designed to completely revitalize the rear suspension of your GM A-Body. By replacing the flimsy stamped steel factory arms with robust, heavy-duty alternatives, you significantly reduce unwanted flex and deflection. This translates directly into improved straight-line traction by minimizing axle wrap, more precise handling during cornering, and a dramatic reduction in dreaded wheel hop under acceleration. The enhanced stability and rigidity allow your vehicle's power to be transferred more efficiently to the pavement, making your muscle car feel more planted, predictable, and responsive in all driving conditions.

Comprehensive Upgrade for Optimal Handling and Durability

My Thoughts

For any A-Body owner serious about performance, whether it's drag racing, autocross, or just spirited street driving, upgrading both upper and lower rear control arms is non-negotiable. It's the most effective way to eliminate wheel hop and get that power to the ground. This comprehensive set provides a solid foundation for any further suspension modifications and dramatically improves the overall driving experience.
