Modular Head Shop » UPR

UPR Products was started in 1989 by long time Ford drag racer Mark Mainiero and his son Joe. Together with their employees Jeremy Martorella and Bart Tobener they amassed more racing victories and records than any other shop. Probably their greatest achievement was building the first 8 second True Street and undefeated 3 time World Ford Challenge winner 95 GT Mustang driven by Willie Figueroa. In 1998 Joe saw a need for a company that truly understood the Mustang racer’s suspension needs. His goal was to offer the strongest, lightest and best-working parts at an affordable price. He made customer service his highest priority and initiated an unconditional guarantee policy. A firm believer in the “keep it simple” philosophy Joe made sure all his components could be easily installed and adjusted. Sales manager and drag tech Jeremy Martorella is a 3-time champion and Billy Glidden protégé. He is always available to answer fine tuning questions by phone or at the track. Since UPR sends a fully-stocked trailer and staff to 22 Mustang events yearly, customers get the opportunity to see parts first hand.

UPR offers a complete chromemoly front K-member kit that shaves 67 pounds off the nose of a Mustang. UPR uses chromemoly tubing rather than mild steel because it enables UPR to use a smaller diameter tube. This gives UPR the best header clearance available while retaining maximum strength. It can be installed in the driveway in less than 3 hours. UPR’s bumpsteer and caster/camber plates complement the front end kit and offer anyone the same package used by most NMRA racers. UPR’s bumpsteer kit offers maximum adjustment and is used to keep the front tires parallel to each other and perpendicular to the track at all times. The bumpsteer kit requires no drilling as it includes custom fit studs rather than plain hex bolts. The caster camber kits allow full alignment adjustment and are offered in both steel and billet aluminum versions.

UPR’s Pro Series rear suspension also sets both performance and price standards. It has enabled racers to achieve 1.15 60’ times on 28 x 10.5 tires or 1.23 60’ times on drag radials. Double adjustable uppers allow quick on-car changes. Chromemoly lowers provide adjustability and strength. UPR’s needle-bearing mounted anti-roll bar keeps both rear tires planted while eliminating chassis twist. Installed in under 3 hours the rear suspension needs only to be adjusted “neutral”-no binding or preload on any bar- with the driver in the racecar.
