Pair of silver anodised aluminium ATV wheel spacers with four bolt holes

RockTrix

RockTrix 5mm 4x156 ATV Wheel Spacers Silver

SKU CH-20HC-Q6RDM

A pair of 5 mm aluminium spacers that widen the track on 4×156 bolt-pattern ATVs and UTVs with hubs up to 131 mm

  • Adds 5 mm track width for better stability
  • 4x156 bolt pattern fits listed Polaris and Kawasaki models
  • 131 mm centre bore matches hub lip limit
  • CNC-machined aerospace billet aluminium resists corrosion
  • Sold as a pair of spacers only

RockTrix 5 mm 4x156 ATV Spacers

This set of two CNC-machined billet-aluminium spacers adds 5 mm of track width per wheel on machines that run a 4x156 bolt pattern. The 131 mm hub-centric bore centres the spacer on the hub lip for a vibration-free fit. Anodised silver finish resists corrosion and rust in muddy or wet conditions. No extended studs or extra hardware are included in the package.

Replaces stock wheels with no offset change

The spacers bolt directly between hub and wheel using the original studs, so installation only requires removing and refitting the wheels. The 5 mm width is worth it when you need a little extra clearance for brake calipers, suspension links or slightly wider tyres without committing to a full-width axle swap. Verify your hub lip does not exceed 131 mm before ordering.

Suits Polaris and Kawasaki owners with 4x156 hubs

Riders fitting aftermarket wheels that sit too far inboard, or anyone chasing a touch more stability on rutted trails, will benefit from the precise hub-centric design. Builders needing a larger bolt pattern, thicker spacers, or included extended studs should look elsewhere. Machines with hub bores larger than 131 mm or non-4x156 patterns cannot use these spacers safely.

Questions about this item

Will these 5 mm spacers clear a hub lip up to 131 mm on my ATV?

Yes, the 131 mm centre bore is designed for hub lips not larger than that dimension, so the spacer seats flat against the hub face.

Do I need longer wheel studs to install the 4x156 spacers?

The listing supplies spacers only; extended studs are not included and must be sourced separately to achieve full thread engagement.

When should the anodised aluminium spacers be inspected or replaced?

Check for corrosion, cracking or elongated bolt holes at each tyre change or after hard off-road use; replace if any damage is found.
