SPC Performance

SPC Performance is an alignment and suspension brand, and its adjustable control arms are the core of the range here. Most listings are upper or lower control arms, arm sets and the joints and bolts that go with them. Smaller groups cover bushings, coil springs, shocks and struts, leveling kits and leaf springs.

The vehicles named across the range are Jeep Wrangler, Jeep Gladiator, Audi A4, Audi A5, Ford Mustang, Infiniti G35, Acura TL, Honda Civic, Honda Accord, Honda CR-V, Subaru Outback and Dodge Charger. Titles often name a platform or a generation rather than a single model, so read the full title.

An adjustable arm replaces a fixed factory arm so that camber or caster can be set after the suspension height changes. That matters most on a lifted or lowered vehicle, where factory alignment limits run out. Sets are sold as a left-and-right pair or as a set of several arms, and some titles are marked race only, so check what the title says before ordering.

For more arms and links, see control arms and track bars, and for the springs side see coil springs. Each product page lists the years, makes and models it fits, and the vehicle selector shows only parts for your vehicle.
