Are these control arms a direct bolt-on replacement?

Yes, these control arms are designed as a direct bolt-on replacement for your stock rear control arms. They are CNC machined for precision tolerances to ensure a proper fit.

Product Details

This kit from UMI Performance gives you a full set of tubular upper and lower rear control arms for your 1978-1988 GM G-Body vehicle, like a Buick Regal, Chevrolet Monte Carlo, or Pontiac Grand Prix. Stock control arms are often made from weak stamped steel and can suffer from bushing deflection, leading to lost traction and sloppy handling. These tubular arms are built to be a direct bolt-on replacement, designed to significantly improve your car's performance whether it's a daily driver or seeing track time.

Built from strong 1.625" OD x 0.120" DOM mild steel tubing, these control arms are fully TIG and MIG welded for a solid construction. They come with high-quality, greasable polyurethane bushings that offer a noticeable improvement over the stock rubber ones. These bushings help reduce deflection, which in turn minimizes wheel hop, improves cornering stability, and helps maintain consistent handling on the track. The lower control arms even include mounting holes for your stock or most aftermarket sway bars.

This kit is finished with a durable powder coat for long-lasting looks and protection. UMI Performance machines these arms to precise tolerances, ensuring they fit right and perform as intended, giving you a well-built upgrade for your G-Body's rear suspension.
