SPC Performance: Frequently Asked Questions (FAQ)

Why do I need SPC adjustable control arms after lifting or lowering my truck or SUV?

Lifting or lowering a vehicle changes suspension geometry, often forcing camber and caster angles out of factory specification. SPC adjustable upper control arms provide up to ±2.0° to ±4.0° of additional adjustment, allowing alignment technicians to dial in correct caster for straight tracking and optimal tire contact.

What is the difference between SPC camber bolts and factory alignment bolts?

Factory alignment bolts often offer limited or no adjustment once a vehicle is modified. SPC eccentric camber bolts replace OEM strut bolts or control arm hardware to provide expanded camber and caster adjustment ranges without requiring permanent modifications to the vehicle frame or knuckle.

Are SPC heavy-duty ball joints greasable and serviceable?

Yes. Most SPC performance control arms feature heavy-duty, greasable ball joints designed with high-articulation housings. They allow smooth suspension travel at extreme angles and can be serviced with standard zerk grease fittings.

Who uses SPC alignment specialty tools?

SPC alignment tools—such as camber/caster gauges, turn plates, ball joint presses, and toe alignment kits—are designed for both professional chassis shops and home mechanics looking to set precise suspension geometry before or after track days and off-road trips.

Will SPC alignment components affect ride quality?

Installing SPC components actually improves ride quality and driving safety on modified vehicles. Correcting suspension geometry reduces darting, bump steer, and harsh handling while ensuring tires wear evenly over time.
