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

BUSY-CORNER 155PCS Auto Body Fender Alignment Shim Kit is a universal zinc-plated steel assortment of U and C type shims for precise fender, door and suspension gap and camber adjustments.

Whether you're restoring a vehicle, aligning fender panels, or fine-tuning wheel geometry, this 155-piece kit supplies a range of thin, slotted shims to correct gaps and tweak angles without welding or cutting. The selection includes two thicknesses (1/16" and 1/8") across U- and C-style profiles and two slot widths (3/8" and 1/2"), all organized in a clear plastic case for quick selection on the bench or in the field. Zinc plating improves corrosion resistance, so the shims stay usable in garages and body shops.

How do these shims help when fitting body panels and fenders?

These shims provide incremental spacing between panels, hinges, or mounting bolts to level gaps and reduce rubbing or misalignment. Using a thin shim is a fast, reversible way to achieve uniform gaps without modifying the vehicle structure. They are especially useful during reassembly after repairs or when swapping body parts.

• Provides precise spacing with 1/16" and 1/8" thickness options
• Slotted design fits 3/8" and 1/2" bolts for common mounting points
• Both U and C profiles adapt to hinge, bracket, and panel edges

Can this kit be used to adjust camber, toe, and caster settings?

The shims are suitable for small adjustments to suspension mounting points that influence camber, caster, and toe when the vehicle design uses shims for alignment. They allow technicians to change mounting geometry without replacing control arms or unequal parts. Use them only where the factory or repair manual indicates shimmed adjustments.

• Use at bolt locations that affect wheel alignment geometry
• Fine-tune angles by stacking shims in small increments
• Keep records of shims added for repeatable alignment results

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

The kit includes 155 zinc-plated steel shims in U-type and C-type profiles across six size variants, covering the most common slot and thickness combinations. The assortment is arranged in a clear plastic storage case so you can identify sizes quickly and carry them to the vehicle. This eliminates rummaging through mixed piles and speeds up on-car adjustments.

• U type: 3/8" x 1/8", 1/2" x 1/8", 3/8" x 1/16", 1/2" x 1/16"
• C type: 3/8" x 1/8", 3/8" x 1/16"
• Total: 155 pieces stored in a transparent plastic box

How durable and corrosion-resistant are the shims?

Each shim is stamped from steel and finished with a zinc plating that adds rust resistance suitable for workshop and garage use. The plating helps protect sharp edges and prolongs service life when shims are used around road salt or in humid conditions. For long-term exposure, consider additional protective coatings or replacing shims as part of regular maintenance.

• Zinc-plated finish for improved corrosion protection
• Stamped steel construction for reliable thickness and strength
• Designed for repeated installation and removal during adjustments
