EMPI Front Caster Shim Set | Air-Cooled VW & Dune Buggy | 4.00° 6061-T6 Billet, Pair (22-3019-0)

EMPI Front Caster Shim Set — 4.00°, 6061 T-6 Billet Aluminum (Pair)

Restore high-speed stability and steering precision to your lowered Volkswagen with the EMPI 4.00° Front Caster Shim Set. When an air-cooled VW is lowered — especially with an adjustable front beam — the caster angle often becomes too vertical, leading to twitchy steering, front-end wander, and poor cornering return.

These shims are precision-machined from 6061 T-6 billet aluminum to tilt the beam back and increase positive caster, improving straight-line highway tracking and steering return-to-center. A single 4-degree shim maintains a more secure, stable mounting surface than stacking multiple thinner shims.

Vehicle Fitment

Fits all standard (non-Super Beetle) air-cooled VW front-axle beams, both ball-joint and link-pin:

• VW Type 1 Beetle (Standard): 1946–1977 (except Super Beetle)
• VW Karmann Ghia: 1956–1974
• VW Type 2 (Bus/Transporter): 1950–1967 (split-window models)
• VW Type 3 (Notchback, Fastback, Squareback): 1961–1973
• Dune Buggy / Sand Rail: Standard VW front beams

Why Choose EMPI?

EMPI machines these shims from 6061 T-6 billet aluminum for a solid, non-compressible mounting surface — a safer, more stable alternative to stacking multiple thin stamped shims.

Frequently Asked Questions

• Will these fit a Super Beetle? No — they are for standard (non-Super Beetle) front axle beams.
• How many come in a set? A pair — enough for one complete front axle beam.
• Why a single billet shim instead of stacking thin ones? A single 6061 T-6 billet shim gives a more secure, stable mounting surface and avoids the risks of stacking.

Installation

Tech Tip: Adding caster shims increases the distance between the beam and the frame head. You may require Longer Front End Mounting Bolts to ensure proper thread engagement. Check your current bolt length before completing installation.
