Function and Mechanics

Camber Bolt Mechanism

Camber bolts are specialized components designed to fine-tune the camber angle of a vehicle’s wheels, improving alignment and performance. Their unique design allows precise adjustments, making them a practical solution for optimizing vehicle handling.

How Camber Bolts Work

The eccentric design of camber bolts, where one side of the bolt shaft is thicker than the other, enables controlled adjustments to the wheel’s tilt. When the bolt is rotated, the offset shape pushes against the suspension mounting points, altering the camber angle. This flexibility allows the user to achieve the desired alignment without major modifications to the suspension system.

Rotating the bolt in one direction tilts the top of the wheel outward, creating positive camber, which enhances stability on straight roads. Conversely, rotating the bolt in the opposite direction tilts the top of the wheel inward, resulting in negative camber, which improves cornering performance by maximizing tire contact during turns.

Stability and Locking Features

Camber bolts include grooves or flutes that interlock with metal tabs on suspension components, preventing unintentional rotation. Once the desired camber angle is set, these features ensure the settings remain stable even under dynamic driving conditions.
