SPC Performance - Alignment Parts & Tools

SPC (Specialty Products Company) has been setting the standard in wheel alignment technology since 1971. Originating in Denver with hand tools, SPC evolved into a global innovator based in Longmont, Colorado, delivering over 1,500 precision parts and alignment tools—from control arms and cam kits to EZ Cams™, shims, and xAxis™ rod ends—many of which are manufactured in-house under ISO‑9001 and IATF‑16949 standards.

SPC empowers both alignment shops and enthusiasts with practical, OE-matched solutions. Their EZ Cams™ add ±1.75° strut adjustability, while Builder Series arms and adjustable control arms serve lifted, lowered, and race-prepped vehicles. The company's commitment extends to deep resources—online & in-person training, alignment apps, and educational materials tailored for professionals .

With a proven record in drift (Papadakis Racing), USTCC, IMSA, and off-road, SPC parts are tested under extreme conditions and trusted for precise alignment, improved handling, and tire longevity
