Description

Modernize your classic GM muscle car's front suspension geometry with the UMI 910-3500B 2-Inch Drop Performance Spindles. Manufactured by Speedway Motors as part of their premier G-Comp line and offered by UMI, these spindles are CNC-machined from high-strength forged 4140 chromoly steel to eliminate structural flex. To deliver unmatched durability and a clean look under your wheel wells, UMI finishes these spindles in-house with a premium, long-lasting black powder coat that provides a highly protective, rust-proof barrier compared to the raw metal alternative.

Designed for 1964–1974 GM A, F, and X-body platforms, including Chevelle, Camaro, and Nova, this kit includes a pair of 2-inch drop spindles. By raising the upper ball joint mount by over two inches, they optimize caster and camber gain during hard cornering while maintaining your factory track width. Compatible with standard power steering arms, OEM-style ball joints, and aftermarket disc brake systems, these spindles are track-validated at UMI Motorsports Park.
