Precision Shims for Automotive Applications
Precision Components for OEM, Workshop and Motorsport
PP Shim manufactures and supplies precision shims and packers for automotive assembly, engine rebuilds, drivetrain work and component alignment across Australia. We supply OEM production lines, independent workshops, motorsport fabricators and parts distributors with shims cut from stainless steel, mild steel, brass and plastic, as standard sizes, custom cuts or pre-sorted kits. We also supply shims across a broad range of industries.
Where Automotive Shims Are Used
Engine Assembly and Rebuilds
Setting bearing clearances, valve lash spacing and component gaps during new-build assembly or overhaul.
Gearbox Spacing and Alignment
Controlling gear mesh, preload and backlash in manual and automatic transmissions.
Brake System Adjustment
Shimming calliper mounts and pad carriers to eliminate play, maintain even pad contact and ensure consistent braking response.
Suspension and Steering
Camber and alignment correction, eliminating play in steering racks, ball joints and suspension bushes. Common in both road vehicles and race applications.
Motorsport and Aftermarket Builds
Fine-tuning clearances for performance modifications, race-spec assemblies and custom fabrication where tolerances are tighter than standard.

Why Automotive Professionals Trust PP Shim
Automotive shims set bearing preload, gear backlash and brake clearances, so small variations in thickness show up as noise, uneven wear or early component failure. Our team cuts each order to the clearance the assembly calls for and helps workshops and production teams choose a material suited to the operating temperature and load.
- Automotive-Grade Materials: Shims manufactured from stainless steel, mild steel, brass and engineering plastics, selected for heat resistance, vibration tolerance and corrosion performance in engine bay and underbody environments.
- Precision-Cut to Tolerance: All shims are cut under ISO 9001 quality management processes for consistent dimensional accuracy across production and one-off orders.
- Custom or Standard: Order from our standard pre-cut range or send us your specifications for custom parts. We handle everything from rare vehicle restorations to high-volume OEM production runs.
- Bulk Supply and Kit Assembly: We supply and package shims in bulk for OEM lines, dealership parts departments and workshop inventory. Kits assembled to your specifications.
- Fast Turnaround, Nationwide: In-house manufacturing with reliable delivery across Australia for both planned orders and urgent workshop callouts.
Compliance & Standards
PP Shim products are manufactured to meet Australian automotive material specifications, including Australian Design Rules (ADR) where applicable, relevant AS/NZS standards and ISO quality management requirements. Our manufacturing operates under ISO 9001 certification.
Frequently Asked Questions
What are shims used for in the automotive industry?
Shims control spacing, alignment and clearances in engines, gearboxes, brakes and suspension systems. They are used to set bearing clearances, correct gear mesh, eliminate play in steering components and fine-tune alignment. Correct shimming is critical for both performance and long-term component life.
Do you supply shims for automotive applications in bulk?
Yes, we regularly produce bulk orders for OEM manufacturers, parts suppliers and service workshops. We also assemble custom shim kits configured to suit specific vehicle platforms or common workshop jobs.
Can you supply custom-sized shims for automotive applications?
Yes, we cut custom shims to your exact specifications, including size, profile and thickness. This covers one-off builds, rare vehicle restorations and non-standard gap requirements that off-the-shelf sizes do not suit.
Where can I buy gearbox shims in Australia?
PP Shim supplies gearbox and drivetrain shims Australia-wide. Order directly through our website or contact our team for a quote. We offer fast turnaround on both standard and custom orders.
What shim materials are available for automotive applications?
We stock stainless steel, mild steel, brass and engineering plastics. Material selection depends on the application, stainless steel and brass for corrosion-prone and high-heat environments, mild steel for general-purpose shimming and plastics for insulation or non-marking applications.
