GOFIRA 15mm Motorcycle Wheel Spacers Kit — 11-Piece Steel Axle Bushings for Pit Bikes

This kit collects the most commonly used inner-diameter 15mm sleeve sizes into one box so you can correct wheel offset, replace worn bushings, and protect your spindle without guessing. Machined from durable steel, each sleeve is built to resist wear and transfer heat away from the axle area. The set covers multiple adjustment needs for 50cc–160cc pit bikes and many imported small motorcycles, giving riders a compact, reliable selection for maintenance or quick swaps at the track.

How will these spacers change my wheel alignment and handling?

Using the correct sleeve thickness restores proper bearing preload and keeps the wheel centered on the spindle, which reduces wobble and uneven tire wear. Installing an accurately sized spacer eliminates lateral play and preserves the original geometry of fork and hub assemblies.

• Provides tight axial support to keep the wheel from shifting side-to-side.
• Prevents bearing over-compression when thicker spacers are needed.
• Helps maintain proper chain/belt alignment when rear spacing is adjusted.

Which sizes are included and how do I choose the right one?

The kit contains 11 sleeves across six common thicknesses (5mm, 10mm, 20mm, 25mm, 30mm, 35mm). Pick a sleeve that matches the removed spacer’s thickness or measure the clearance you need between hub and fork to select the closest size. If you’re unsure, test fit from smallest to largest until wheel runs true with correct bearing preload.

• Six available thicknesses for fine-tuning axle position.
• Universal 15mm inner diameter for standard pit bike axles.
• 11 pieces total to cover multiple setups and spares for the toolkit.

Are these bushings durable enough for off-road and track use?

Manufactured from high-grade steel, the sleeves are engineered for wear resistance and thermal conductivity to stand up under repeated load cycles. Properly fitted steel sleeves reduce localized shaft wear and help transfer heat away from bearings, extending component life under demanding conditions.

• Precision-machined for consistent fit and minimal vibration.
• Steel construction resists deformation under load and heat.
• Designed to protect the axle and reduce maintenance frequency.

What should I check before installing these axle spacers?

Measure the original spacer thickness and inspect the axle and hub surfaces for damage before installing any new sleeve. Using the wrong thickness can cause bearing overload or improper wheel alignment, so confirm inner diameter, outer contact surfaces, and overall length match your application.

• Confirm your axle is 15mm in diameter before purchase.
• Measure original sleeve thickness and hub clearances to pick the right piece.
• Look for burrs or corrosion on the spindle and clean before fitting.

Who is this for: The GOFIRA 15mm Wheel Spacers Kit is for riders, mechanics, and racers who work on 50cc–160cc pit bikes, small off-road motorcycles, or imported models using 15mm axles. It suits anyone who needs a reliable, versatile selection of steel sleeves for maintenance, wheel setup, or to carry as spare parts at the track. If you value precise fitment, component protection, and a compact set that covers common spacer needs, this kit belongs in your toolbox.
