SPL Pro Suspension

About SPL Parts Pro Suspension

Born in Austin, Texas, SPL Parts has built a reputation as one of North America's premier manufacturers of fully adjustable, high-performance suspension components. SPL Parts Pro Suspension products are trusted by professional racing teams and passionate street-car enthusiasts alike — the very definition of a brand that bridges the gap between the race track and the daily commute.

What sets SPL Parts apart is an uncompromising commitment to domestic manufacturing. Every component is machined from USA-sourced materials using CNC precision techniques, then expertly TIG welded to exact tolerances. The result is hardware that delivers four core qualities racers and tuners demand: strength, lightweight construction, low friction, and precision. These aren't off-the-shelf parts — they are purpose-built tools for anyone who takes their chassis setup seriously.

What SPL Parts Makes

SPL Parts specializes in adjustable suspension geometry components. Their catalog spans a wide range of product types designed to give drivers control over alignment parameters that factory suspension simply doesn't allow. Whether you're dialing in camber after a lowering spring install, correcting bumpsteer caused by modified ride heights, or building a dedicated track car that demands race-grade components, SPL has purpose-made solutions.

Their suspension control arms are among their most celebrated products, covering popular platforms from BMW, Subaru, Porsche, Toyota, Ford Mustang, and Chevrolet Camaro. Paired with their precisely engineered suspension trailing arms, these components allow tuners to unlock camber, toe, and track width adjustability that factory geometry locks away. For the front end, SPL's steering tie rod ends are a go-to upgrade for correcting bumpsteer that creeps in after lowering or alignment modifications — featuring relocated pivot points and wide-range adjustment that OEM tie rods can't match.

Completing the system are SPL's suspension control arm bushings, which replace compliant rubber OEM bushings with spherical, PTFE-lined bearings. The upgrade eliminates bushing deflection — a common culprit of vague steering feel and inconsistent alignment under load — while delivering sharper, more communicative feedback from the suspension.

Who Trusts SPL Parts?

SPL Parts has earned endorsements from top-tier race teams and appears on podium-finishing builds around the world. Their dealer network spans the globe, and their parts ship internationally, making them accessible to enthusiasts whether they're prepping a Subaru WRX for autocross, a BMW M3 for track days, or a Porsche 911 for dedicated circuit racing. For drivers who want to truly tune their suspension — not just replace worn parts — SPL Parts is a name that consistently delivers the adjustability and reliability to make it happen.
