Description

Elevate the handling of your classic muscle car with UMI's 2752 tubular lower A-arms — the ultimate front suspension upgrade for superior strength, precision, and track-level response. Fabricated in-house from high-strength 1.5-inch OD .120 wall DOM tubing, these arms are CNC-bent and jig-welded to deliver exact tolerances and a clean, race-ready look. Designed specifically to improve ball joint angles on lowered vehicles, they correct camber and increase caster to give your vintage chassis a modern, planted feel. This specific 2752 kit upgrades the pivot points to zero-deflection Delrin bushings, ideal for serious autocrossers and track day enthusiasts demanding bind-free articulation.

Engineered for 1967–1969 Camaro and Firebird (F-Body) as well as 1968–1974 Nova (X-Body), the 2752 kit drops right in with factory spindles and works flawlessly with factory springs, lowering springs, or coilover kits. Each arm ships fully assembled with premium standard-length ball joints, Delrin bushings, and repositionable polyurethane bump stops to fit both frame styles used across the early platforms. Pair them with UMI upper A-arms for maximum performance, and trust in a product proudly designed, track-tested, and manufactured 100% in the USA.

Product FAQ

What vehicles do these lower A-arms fit?
The 2752 lower A-arms fit the 1967–1969 Camaro and Firebird, as well as the 1968–1974 Chevy Nova. Note that they do not fit vehicles equipped with drum brakes.
What is the difference between the 2751 and 2752 A-arms?
The UMI 2752 kit features zero-deflection Delrin bushings for ultimate track performance, whereas the 2751 kit uses polyurethane bushings which are better suited for street comfort.
Do these arms improve handling geometry?
Yes. They are designed to correct camber and increase caster for vehicles at a stock ride height down to a 2-inch drop using a factory spindle.
Are the ball joints and bushings included?
Yes. Each arm comes fully assembled with premium standard-length ball joints and Delrin bushings already installed.
What springs can I use with these lower control arms?
The UMI 2752 A-arms are highly versatile and compatible with factory springs, lowering springs, and coilover kits.
Will these work with drop spindles?
Yes. They can be paired with a 2-inch drop spindle (like part 910-3500B) to achieve greater than a 2-inch overall drop while maintaining near-zero camber.
My first-gen has a specific frame style. Will these fit?
Yes. UMI built these to be universally compatible with early frames by including steering stop pads welded fore and aft and a repositionable polyurethane bump stop.
What materials are the A-arms made from?
They are precision jig-welded from high-strength 1.5-inch OD .120 wall DOM steel tubing, CNC-bent for superior structural integrity.
Does the kit include installation hardware?
The arms include the necessary sway bar end links and bump stops, but frame mounting hardware is not included. We recommend purchasing UMI hardware kit 4001 or 4002.
Why choose UMI 2752 lower A-arms over the competition?
They offer race-proven geometry, robust DOM steel construction, friction-free Delrin pivot points, and are proudly 100% Made in the USA in Philipsburg, PA.
