Part Name: Washer for Bolt-On Style Wobble Roller
Part Number: 290-022947

Designed for Wobble Roller Systems

This washer is used on EZ Loader trailers equipped with bolt-on wobble rollers. It supports the roller mounting bolt and distributes clamping force across the bracket to maintain proper alignment under load.

Fitment-Specific Design

This is not a universal washer.

• 5/8" inner diameter matches roller mounting bolt size
• 1-1/2" outer diameter provides correct load distribution
• designed to match EZ Loader roller bracket geometry
• Correct washer size is critical 

👉 Proper fitment depends on matching the original roller hardware dimensions.

Zinc-Plated Steel Construction

• high strength for clamping applications
• corrosion resistance for marine environments
• durable under repeated launching conditions

Compared to generic or undersized washers:

• provides better load support
• reduces risk of bracket deformation
• maintains consistent clamping force

Specifications

• Inner Diameter: 5/8"
• Outer Diameter: 1-1/2"
• Material: Zinc-Plated Steel

Why This Part Matters

👉 Ensures proper clamping and alignment within the wobble roller system.

Using incorrect or undersized washers can lead to uneven clamping, roller misalignment, and premature wear of brackets and hardware.
