eccentric bolts

OE NO.:    30873186  30741284

Applicable vehicle type: For Volvo

The caster correction screw (also known as an eccentric screw or eccentric bolt) is a specially designed suspension system fastener primarily used for precise adjustment of the wheel caster during four-wheel alignment. When the caster angle deviates from the standard range due to accidents, deformation of suspension components, or modifications, this screw enables angle correction without replacing suspension parts.

Main Application Scenarios

1. Maintenance and Accident Repair

• Deformed Suspension Components: Deformation of control arms and shock absorber mounting brackets caused by collisions, making it impossible to restore the standard camber angle through original factory hole positions.
• Camber/Shock Absorber Replacement: After installing non-standard parts, the camber angle parameters need to be rematched.

2. Modification and Performance Upgrade

• Lowering Shock Absorber Modification: After reducing the vehicle body height, the camber angle needs to be readjusted to ensure the tire contact area.
• Racing Calibration: Race cars or performance vehicles require setting a specific negative camber angle to improve cornering grip.

3. Routine Four-Wheel Alignment

• Camber Angle Exceeding Standards: When detected data exceeds the ±0.5° range, eccentric bolts are used for fine adjustment.
• Abnormal Tire Wear: Solving problems of excessive wear on the inner or outer side of tires.
