Alignment Caster / Camber Cam Bolt

What Are Alignment Caster / Camber Cam Bolts?

Alignment caster and camber cam bolts are precision suspension fasteners engineered to give technicians and enthusiasts fine-grained control over two of the most critical wheel alignment angles. Camber refers to the inward or outward tilt of the wheels when viewed from the front of the vehicle, while caster describes the forward or rearward angle of the steering pivot point when viewed from the side. Together, these angles determine how your tires contact the road — and getting them right is essential for predictable handling, straight-line stability, and even tire wear.

Cam bolts feature an off-center, eccentric design: the threaded stud is intentionally offset from the washer, so rotating the bolt shifts the position of the control arm or strut, adding or removing degrees of camber or caster as needed. They are typically installed at the control arms or struts, giving mechanics the ability to adjust the angle of the wheels during an alignment service.

Why Cam Bolts Matter for Your Suspension

Many vehicles come from the factory with limited or no built-in camber/caster adjustment. After a suspension lift, lowering springs, collision damage, or simply years of hard use, the factory geometry can shift outside of acceptable specifications. In those situations, cam bolts become an essential tool for restoring — or improving upon — proper alignment without requiring a full control arm replacement.

The consequences of neglecting alignment angles are tangible: uneven tire wear, a vehicle that pulls to one side, vague or heavy steering, and reduced fuel efficiency. A proper set of cam bolts restores the geometry that keeps all four corners working together.

Cam bolts are especially valuable for lifted trucks and SUVs. When you raise a vehicle's ride height, you alter the relationship between the upper and lower ball joints, which can push camber and caster outside the range that stock hardware can correct. Installing aftermarket cam bolts at the lower control arms gives the alignment tech the range of motion needed to bring everything back into spec — and even dial in a bit of extra positive caster for improved straight-line stability and steering return.

What to Look for When Shopping Cam Bolts

• Adjustment range: Aftermarket cam bolts typically offer more adjustment range than OEM replacements — make sure the range is sufficient for your lift height or modification level.
• Corrosion resistance: These bolts live in a harsh, road-salt-exposed environment and are adjusted infrequently, making them prone to seizing. Look for parts with robust corrosion-resistant finishes.
• Vehicle fitment: Cam bolt dimensions vary widely by make, model, and suspension type — always verify fitment before purchasing.
• Hardware quality: Heavy-duty designs that exceed OEM strength specifications are important, especially for trucks, SUVs, or vehicles used in demanding driving conditions.
