SPC Performance 10462 Al Shims 2.5x5x3.5 (6)

The SPC Performance 10462 aluminum axle shims are a cost-effective solution for correcting caster on over-the-road heavy duty trucks and trailers. Measuring 2.5" wide x 5" long with a 3.5-degree taper, these leaf spring shims are manufactured from aluminum alloy and are designed for use on heavy duty and fleet vehicles equipped with leaf spring suspensions.

Key Features:

• Aluminum alloy construction provides good compression strength and hardness for reliable heavy duty service
• 3.5-degree taper angle for effective caster correction on over-the-road trucks and trailers
• 2.5" spring pad width fits a wide range of HD leaf spring applications
• USA-made by Specialty Products Company (SPC), a recognized leader in alignment parts
• Economical option within SPC's multi-alloy shim lineup (Aluminum, Zinc, Manganese-Bronze, and Steel)
• Each box contains six (6) shims — one part number supplies a full set

SPC offers truck axle caster shims in multiple alloy grades to match both price point and mechanical requirements. The aluminum alloy shims in this series represent the entry-level option in SPC's HD shim range. When ordering, confirm your spring pad length and width to ensure proper fitment. If used alongside Z-blocks or other axle spacers, a load-spreading spacer plate is recommended to prevent shim compression.
