Hotchkis Sport Suspension Tubular Lower A-Arms for 70-81 Camaro & Firebird – Part 1108

Description

Upgrade your classic Camaro or Firebird with the Hotchkis Sport Suspension geometry corrected tubular lower A-Arms, designed specifically for models from 1970 to 1981. These TIG-welded, bolt-on components are engineered to significantly enhance handling, stability, and traction by re-positioning the ball joints to increase caster and optimize camber curves. The result is improved steering response and cornering performance, making them ideal for enthusiasts seeking ultimate control.
Constructed from durable 1.5-inch tubular steel, each A-arm features a CNC-machined inset spring cup for increased structural rigidity and precision fit. The design includes built-in camber adjustment of approximately -0.6 degrees and caster of 2 degrees, providing a tailored stance to match your vehicle’s setup. An included set of aluminum ride height shims allows for a range of height adjustments from 0.25 to 0.50 inches, enabling you to fine-tune your ride height for optimal performance and aesthetics. The gloss black powder coat finish not only provides corrosion resistance but also delivers a sleek, professional appearance ready for installation.
The arms are equipped with maintenance-friendly Delrin bushings that facilitate smooth movement and minimal deflection during operation. Installed ball joints and polyurethane coil spring locators are included, ensuring a complete solution for upgrading your suspension system. When combined with Hotchkis’s tubular upper A-Arms, these lower arms contribute to a comprehensive geometry correction package, significantly increasing maximum caster to 9 degrees and camber to -3.5 degrees.
Designed and analyzed via FEA software, these parts deliver optimal strength, durability, and performance, backed by Made in USA quality standards. Suitable for a range of classic muscle cars, including the 1970-81 Camaro and Firebird, as well as 1975-79 Nova, these lower A-Arms are a critical upgrade for enthusiasts looking to improve handling and appearance without sacrificing reliability.
