<h3>About SPC Performance (Specialty Products Company)</h3><p><strong>Specialty Products Company (SPC)</strong>, based in Longmont, Colorado, has been designing and manufacturing innovative automotive suspension and alignment parts since 1971. <a href="/638-spc-performance">SPC Performance</a> is widely recognized as the world leader in wheel alignment parts development, manufacturing, and sales — a reputation built over five decades of engineering excellence and real-world validation.</p><p>What started as a small specialty automotive tool company grew rapidly into a global force in suspension and alignment technology. <a href="/638-spc-performance">SPC</a> operates under two primary brands: Specialty Products for the traditional aftermarket and OE service markets, and SPC Performance for off-road, track, and enthusiast applications. Today, the company offers more than 1,500 parts and tools to customers worldwide, and many of those parts are still manufactured in-house using extensive mill, lathe, laser, and fabrication capabilities. SPC is also proud to hold <strong>ISO 9001 &amp; IATF 16949</strong> certifications, reflecting their commitment to consistent quality standards.</p><h3>Engineering for Every Application</h3><p>SPC's core insight is straightforward: when you lower, lift, or modify a vehicle, the factory suspension geometry no longer delivers optimal alignment angles. <a href="/638-spc-performance-alignment-camber-kit-7436">SPC Performance alignment camber kits</a> and adjustable components restore proper geometry, improving tire wear, handling, and safety. Whether you're correcting factory camber issues on a lowered street car, dialing in a lifted truck, or optimizing a dedicated race build, SPC engineers a solution for the task.</p><p>The company's motorsports credentials are equally impressive. <a href="/638-spc-performance">SPC Performance</a> has sponsored Papadakis Racing — the most winning drift team in history — through multiple Formula Drift Championship titles, proving that their components can endure the punishment of elite competition before ever finding their way onto a daily driver.</p><h3>Core Product Lines</h3><p>SPC Performance's catalog covers the full spectrum of suspension geometry correction. Their <a href="/638-spc-performance-suspension-control-arm-10401">suspension control arms</a> are among their most popular products, available in preassembled adjustable configurations for circle track, road racing, drag, and street use. These fully adjustable arms let technicians and enthusiasts dial in precise camber and caster values to suit any application.</p><p>For vehicles where a full control arm replacement isn't required, <a href="/638-spc-performance-alignment-caster-camber-control-arm-20423">alignment caster/camber control arms</a> provide targeted correction in a direct-fit format. Paired with SPC's <a href="/638-spc-performance-suspension-control-arm-bushing-kit-10489">suspension control arm bushing kits</a> and individual <a href="/638-spc-performance-suspension-control-arm-bushing-7532">suspension control arm bushings</a>, these solutions allow builders to restore or upgrade the entire pivot interface of a control arm, addressing both alignment and NVH characteristics in one pass.</p><p>Professional installers have long preferred SPC for the brand's combination of fitment accuracy, technical documentation, and hands-on support. SPC even offers a free online wheel alignment training course for performance vehicles, reinforcing their identity not just as a parts manufacturer, but as an alignment education resource for the industry.</p><h3>Who Should Choose SPC Performance?</h3><ul style="list-style:disc"><li>Enthusiasts running lowered or lifted builds who need alignment correction beyond factory adjustment range</li><li>Track-day and motorsports competitors requiring precise, repeatable camber and caster settings</li><li>Professional alignment technicians seeking OE-compatible or performance-upgrade components</li><li>Truck and SUV owners correcting geometry after lift kit installation</li></ul><p>From street to strip to circuit, SPC Performance delivers engineered alignment solutions backed by decades of manufacturing experience and competitive validation.</p>
