UPR Suspension Products

Aftermarket Suspension Parts Built in the USA, Built for Performance

Most aftermarket suspension parts share the same basic promise: better handling, less wheel hop, improved geometry. What separates UPR from the shelf-filler options is how we make those parts. We design, weld, and machine every UPR suspension product at our facility in the United States, using 4130 chromoly or DOM steel tubing, CNC-machined billet fixtures, and hardware that doesn't cut corners where it matters. TIG welds are laid in billet fixtures for consistency. Ball joints come with zerk fittings for real-world serviceability. These aren't parts that look aggressive in photos and fail in six months.

Our suspension lineup runs three distinct tiers, each designed for a specific type of builder.

Pro-Street Series components are for the street enthusiast who wants a meaningful upgrade from factory rubber bushings without sacrificing daily drivability: urethane bushings, fixture-welded tubular construction, and a substantial step up in chassis rigidity over stock.

Pro-Series moves the dial for the serious street/strip car or weekend warrior, using lightweight chromoly tubing and rod ends to eliminate the slop and deflection that factory stamped arms and rubber mounts introduce under load.

Extreme Series is competition hardware: upgraded rod ends, maximum-strength chromoly tubing, and hardware spec'd to withstand repeated hard launches without fatigue. Most builders running boost, a power adder, or anything over 500 horsepower at the tire are looking at Pro-Series or Extreme.

The Core Categories and How They Work Together

Suspension performance comes from the system, not individual parts. A K-member kit can shed up to 80 lbs from the front of the chassis. But the geometry correction it enables is fully realized only when paired with the right tubular control arms. We engineer our upper and lower control arms around UPR K-member geometry, correcting roll center height for lowered cars and keeping camber curves in check under hard cornering. Running them on a factory K-member compromises that engineering. They're designed as a system for a reason.

From there, caster camber plates give you adjustable authority over front-end geometry once the car is lowered or on coilovers. Our billet aluminum plates use Teflon-lined spherical bearings and replace the factory rubber strut mount bushings that go vague under load. For ride height and damping control as part of a UPR suspension system, our coilover kits use military-style threaded bodies with nylon-tipped set screws that hold adjustment without seizing. On the rear, Anti-Roll bars round out the package: TIG-welded chromoly bar stock with spherical or urethane mounts that give the rear end a far more direct response than the factory rubber-bushed stabilizer bars ever could.

UPR offers a wide range of suspension, coilovers, control arms and more for maximum Mustang performance.

Frequently Asked Questions

Where are UPR products made?

We design, weld, and machine UPR Products at our facility in Lake Worth, Florida. All welding and materials are domestic, and every suspension component goes through our quality control process before it ships. When the product page says "Made in the USA," it means the part was built here.

What are UPR suspension products used for?

Our suspension products correct the geometry, reduce weight, and eliminate the compliance introduced by factory suspension, particularly on high-output or lowered builds where OEM stamped components and rubber bushings quickly reach their limits. Specific use cases include reducing wheel hop on hard launches, correcting camber curves on lowered Fox Body or SN95 Mustangs, gaining header and oil pan clearance with a tubular K-member swap, and dialing in front-end geometry for road course or autocross applications.

What suspension components does UPR offer?

Our full suspension lineup covers K-member kits, upper and lower control arms, tubular A-arms, coilover kits, caster camber plates, bump steer kits, sway bars, anti-roll bar kits, lowering springs, lowering kits, shocks and struts, and associated hardware and bushing sets. Most categories offer multiple configurations across the Pro-Street, Pro-Series, and Extreme Series tiers to match your build and budget.

What vehicles are UPR suspension products compatible with?

The core of our suspension lineup is built around the Ford Mustang: Fox Body (1979-1993), SN95 (1994-2004), and S197 (2005-2014) generations. Many K-member and control arm applications also support engine swaps, including LS and Coyote swaps for the Fox Body platform. Select components are available for GM and Dodge applications as well. Each product page lists specific year and model fitment, and our team at 561-588-6630 can help confirm compatibility for nonstandard builds or engine swaps before you order.
