Alignment Cam Bolt

What Is an Alignment Cam Bolt?

An alignment cam bolt is a specialized suspension fastener that gives technicians and enthusiasts the ability to make precise adjustments to a vehicle's wheel alignment angles. Camber — the tilt of the wheel when viewed from the front or rear of the vehicle — is the primary angle these bolts target, though many cam bolt kits also address caster and toe settings. The bolt's threaded stud is offset, or eccentric, relative to the cam washer it seats against; rotating the bolt within its slotted mounting hole shifts the position of the suspension component it secures, dialing in the desired angle before the nut is tightened to lock everything in place.

Why Alignment Cam Bolts Matter

Proper wheel alignment isn't just about keeping a car tracking straight. Misaligned wheels cause uneven and accelerated tire wear, increase rolling resistance, put added stress on steering and suspension components, and can compromise handling in emergency situations. Alignment cam bolts are the mechanism that makes fine-tuning these angles possible without replacing entire suspension assemblies.

Cam bolts become especially important after suspension repairs or parts replacement — new control arms, struts, or ball joints can shift the geometry slightly from factory spec. They are equally valuable when a vehicle is lowered, lifted, or fitted with wider tires, situations where stock alignment positions are often no longer sufficient. Even a minor encounter with a pothole or curb can knock alignment out of specification, and cam bolts are the most targeted way to bring it back.

What to Look For When Shopping Alignment Cam Bolts

• Vehicle Fitment: Cam bolt dimensions, thread pitch, and cam washer geometry vary by make and model. Always verify fitment before purchasing.
• Adjustment Range: Stock-replacement cam bolts restore factory geometry. Performance or "aftermarket adjustment" cam bolts offer a wider range — often ±1.75° or more — for lifted, lowered, or track-prepared vehicles.
• Kit Contents: Many cam bolt kits include matching nuts, washers, and cam plates. Confirm what's included so you have everything needed to complete the job.
• Corrosion Protection: Look for bolts with a zinc coating or other protective finish, particularly if the vehicle operates in high-moisture or road-salt environments.
• OE Replacement vs. Adjustable Upgrade: Some vehicles leave the factory without adjustable cam bolts. Aftermarket kits can add adjustability to previously non-adjustable mounting points, unlocking alignment correction that the factory design didn't provide.
