Front Caster Shim Set - 5.25 Degrees - 6061 T-6 Aluminum (Pair)

Front Caster Shim Set - 5.25 Degrees - 6061 T-6 Aluminum (Pair)Correct extreme front end geometry issues with the EMPI 5. 25 Degree Front Caster Shim Set. Specifically engineered for "slammed" or ultra lowered air cooled Volkswagens, these shims are the most aggressive single shim solution available. When you lower a VW front end significantly, the beam pivots forward, losing the positive caster required for stable handling. This results in "bump steer," front end wandering at highway speeds, and a steering wheel

Correct extreme front-end geometry issues with the EMPI 5.25 Degree Front Caster Shim Set. Specifically engineered for "slammed" or ultra-lowered air-cooled Volkswagens, these shims are the most aggressive single-shim solution available. When you lower a VW front end significantly, the beam pivots forward, losing the positive caster required for stable handling. This results in "bump steer," front-end wandering at highway speeds, and a steering wheel that refuses to return to center.

By installing these 5.25-degree shims, you tilt the entire axle beam back, restoring necessary positive caster. This significantly improves straight-line tracking and gives the driver more confidence during high-speed cruising. Machined from high-strength 6061 T-6 Billet Aluminum, these shims provide a solid, singular mounting surface that is far safer and more stable than stacking multiple thinner shims.

Key Features

• Extreme Adjustment: Provides 5.25 degrees of caster—ideal for vehicles with narrowed and adjustable beams or extreme drops.

• Billet Aluminum Construction: CNC-machined from 6061 T-6 aluminum to prevent compression or shifting under suspension load.

• High-Speed Stability: Eliminates the "twitchy" feeling of lowered front ends by re-establishing correct suspension rake.

• Safety First: A single-shim design eliminates the risks of "shim walk" or bolt loosening often caused by stacking thin plates.

• Sold as a Pair: Includes two precision-matched shims for one complete front axle beam.

Vehicle Fitment

Fits all standard (non-Super Beetle) air-cooled VW front axle beams (Ball-Joint and Link-Pin).

Tech Tip: Because 5.25 degrees adds significant thickness between the beam and the frame head, Longer Front End Mounting Bolts are mandatory for a safe installation. Ensure you have at least 1/2" to 5/8" of thread engagement into the frame head.
