PFA Aston Martin Caster Shim in Stainless Steel Classic Models DB4 Onwards

Aston Martin Stainless Steel Front Suspension Caster Shim (DB4 Onwards)

Eliminate corrosion and maintain precise front-end alignment on your classic grand tourer using the PFA Stainless Steel Caster Shim. We manufacture these precision shims strictly to original equipment dimensions, upgrading the material to high-grade stainless steel to prevent the rust, swelling, and structural degradation common with original factory components.

Product Overview

Front suspension shims endure constant environmental exposure, moisture trap risks, and high clamping loads. Original steel shims frequently rust and flake over decades, compromising suspension geometry and tightening integrity. Therefore, our upgraded stainless steel construction guarantees lifetime corrosion resistance and stable shim stacks.

• Vehicle Compatibility: Purpose-built to fit classic Aston Martin models from the DB4 era onwards, including:

  • Aston Martin DB4

  • Aston Martin DB5

  • Aston Martin DB6 & DB6 Mk2

  • Aston Martin DBS6

  • Aston Martin DBSV8

  • Aston Martin AM Vantage & AMV8

• Quantity Required: Typically 16 items per side (32 shims in total per complete car set on a 6-cylinder model). Please note: This listing is priced and sold individually for a single shim.

• Quality: Precision-cut to OE thickness and contour for exact caster and camber adjustment without pinching or distortion.

Why Choose Our Stainless Steel Caster Shims?

Achieving correct front suspension alignment is vital for high-speed stability and even tire wear on a classic Aston Martin. Standard steel shims rust over time, altering stack thickness and introducing play into the control arm mounts. Consequently, upgrading to our stainless steel shims ensures permanent corrosion immunity, clean disassembly during future alignment adjustments, and factory-accurate geometry across your DB or V8 chassis.
