Alignment Caster / Camber Cam
What Are Alignment Caster / Camber Cams?
Caster and camber are two of the most fundamental angles in any wheel alignment, and getting them right has a direct impact on how your vehicle handles, how quickly your tires wear, and how connected you feel behind the wheel. Camber describes the inward or outward tilt of a wheel when viewed from the front of the vehicle — negative camber means the top of the tire leans inward, while positive camber means it leans outward. Caster refers to the forward or rearward angle of the steering axis relative to vertical, and it plays a major role in steering feel and high-speed stability.
A caster/camber cam — commonly sold as a cam bolt or cam bolt kit — is a precision hardware solution that replaces a vehicle's fixed control arm mounting bolt with an eccentric-style adjuster. By rotating the cam within its mounting slot, a technician can shift the position of the control arm and dial in the exact caster or camber angle needed. These kits are engineered to install in the upper or lower control arms and provide measurable degrees of adjustment without requiring major suspension fabrication.
Why Caster and Camber Adjustability Matters
On many vehicles, camber and caster are not adjustable from the factory, or the range of factory adjustment is too narrow to address real-world situations. Suspension modifications, body lifts, lowering springs, collision damage, or simply years of wear can all push alignment angles outside of spec. When that happens, a cam bolt kit restores proper geometry without replacing the entire suspension.
Beyond correction, cam-style adjusters are also widely used for performance tuning. Vehicles that have been lowered or modified for track use often benefit from dialing in additional negative camber to maximize the tire's contact patch during cornering. Because alignment preferences can vary with driving style, track layout, and even weather conditions, having a genuinely adjustable setup is a meaningful advantage for any enthusiast.
Lifted and Lowered Vehicles
Changing a vehicle's ride height — whether by lifting it for off-road clearance or lowering it for performance — almost always moves caster and camber out of their factory specification range. Cam bolt kits are one of the most cost-effective solutions for bringing alignment back within acceptable limits after a suspension height change, often without requiring replacement control arms or more expensive geometry corrections.
Top Brands in Alignment Caster / Camber Cams
SPC Performance is the dominant name in this category, and for good reason. As a brand under Specialty Products Company — a company that has positioned itself as an automotive alignment leader — SPC offers a broad catalog of vehicle-specific cam bolt kits covering everything from Toyota trucks and SUVs to GM HD pickups, Ford Rangers, and Dodge LX-platform vehicles. Their kits are engineered to install directly into existing control arm locations, delivering precise, repeatable adjustment without additional modifications. The quality of finish on SPC hardware is noteworthy as well, with corrosion-resistant coatings designed to hold up to long-term exposure.
Triple X Race Components brings a purpose-built racing pedigree to this category. Known for their race-proven Sprint Car, Midget, and Mini Sprint chassis and components, Triple X Race Components serves competitors who demand tight tolerances and reliable adjustability under race conditions — making their caster/camber hardware a natural fit for serious motorsport builds.
