Modernize your classic's steering geometry with Speedway Motors G-Comp forged 4140 chromoly spindles, offered by UMI in a durable, rust-proof black powder coat.
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.
Overview & Difficulty: Moderate DIY install requiring basic hand tools (jack stands, floor jack, torque wrench, socket set, ball joint separator, hammer); takes 2–3 hours per side. Steps involve removing calipers and rotors, separating tie rods and ball joints, mounting the new spindles, and torquing hardware to spec. Torque upper ball joint nuts to 50 ft-lbs, lower ball joints to 65 ft-lbs, steering arm/caliper bracket bolts to 85 ft-lbs, and calipers to 35 ft-lbs. A professional front-end alignment is mandatory immediately following installation.
These Speedway Motors G-Comp performance spindles, enhanced by UMI's premium black powder-coated finish, are ideal for classic GM muscle car owners. They solve primitive factory geometry and provide a true two-inch drop, delivering improved cornering grip and reliable, rust-free durability on the street or track.
