Hotchkis 64-72 GM A-Body Lower A-Arms

Hotchkis Sport Suspension is known for making well-built suspension components that improve a vehicle's handling. If you're looking to significantly upgrade the cornering ability and overall control of your classic GM A-Body, these tubular lower control arms are a solid choice. They're designed to correct geometry issues and are built to handle the demands of spirited driving, whether you're cruising or hitting the track. These arms fit a wide range of popular vehicles from 1964 to 1972, including models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark.

These aren't just simple replacements; they're a performance upgrade. The arms are constructed from 1.5-inch tubular steel and are 100% TIG-welded for maximum strength and rigidity. Hotchkis uses smooth-operating Delrin bushings, which allow the control arms to move freely through their travel with minimal deflection, contributing to a more responsive feel. The design also incorporates a CNC-machined inset spring cup for increased structural rigidity. Plus, they offer precision aluminum ride height adjustment shims, allowing you to dial in your vehicle's stance from a quarter-inch to a half-inch lower than stock, which also helps optimize suspension geometry.

When you receive these lower A-arms, they come ready to install. They include the lower ball joint already pressed in, along with bump stops, polyurethane coil spring locators, and the ride height adjustment shims. The entire assembly is finished in a durable gloss black powder coat to resist corrosion and look great. For the best results and a complete suspension overhaul, Hotchkis recommends pairing these lower A-arms with their tubular upper A-arms.
