BUSY-CORNER Auto Body Fender Alignment Shim Kit 155PCS — 1/16 in & 1/8 in Zinc-Plated, 3/8 in & 1/2 in Slots

BUSY-CORNER 155PCS Auto Body Fender Alignment Shim kit is a ready-to-use assortment of zinc-plated steel U and C shims in 1/16" and 1/8" thicknesses designed to fine-tune fender gaps, camber, toe and panel alignment quickly and reliably.

Whether you’re a pro technician or a home mechanic, keeping panels and wheel alignment gaps consistent requires small, precise spacers. This kit bundles 155 corrosion-resistant shims in six commonly used sizes, organized in a transparent plastic box so you can pick the exact thickness and slot configuration for fast, repeatable adjustments.

How do these shims help with fender and panel alignment?

The shims sit between body panels, brackets or suspension components to correct misalignments without expensive replacement parts. Adding or removing a shim changes the gap or angle in small, predictable increments so you can achieve even panel fitment and better visual alignment.

• Use U- and C-type shims for flange or slot applications where slot width is 3/8" or 1/2".
• Choose 1/16" for fine adjustments, 1/8" for larger corrections.
• Zinc plating helps them resist rust when exposed to road conditions.

What sizes and quantities are included, and how are they organized?

The kit contains 155 pieces in two profile types (U and C) covering six size combinations commonly used on vehicle bodies and suspension mounts. Sizes are clearly marked and stored in a compartmented clear plastic box so you can quickly identify the right shim without sifting through loose parts.

• U-type sizes: 3/8" x 1/8", 1/2" x 1/8", 3/8" x 1/16", 1/2" x 1/16".
• C-type sizes: 3/8" x 1/8", 3/8" x 1/16".
• Total count: 155 zinc-plated steel shims in a transparent organizer box.

Which vehicle tasks are these shims appropriate for?

These universal body shims are designed for a wide range of alignment tasks: correcting camber and toe, shimming fenders and doors, and adjusting mounts or brackets to reduce gaps and improve fit. They are not vehicle-specific, so they work across many makes and models for both front and rear adjustments.

• Adjust camber, toe and caster where small thickness changes are needed.
• Correct uneven fender or door gaps without welding or replacing parts.
• Use with brackets and mount slots sized for 3/8" and 1/2" widths.

How durable are these shims, and how do I store them?

Each shim is stamped from zinc-plated steel to resist corrosion and maintain stiffness under load. The kit ships in a compact, transparent plastic box with compartments so shims stay separated, easy to access, and protected from moisture or shop contaminants.

• Zinc plating improves rust resistance in automotive environments.
• Steel construction preserves shape under clamping and pressure.
• Clear compartmented box organizes sizes for fast selection and storage.

If you work on vehicles regularly and want a compact assortment of reliable shims for trimming gaps, correcting camber or shimming mounts without fabricating parts, this kit provides the sizes and organization to speed up the job.
