Aggressive Stance for 4x156 ATVs

These RockTrix wheel spacers widen the track by 25mm on machines that run a 4x156 bolt pattern with a 131mm hub bore and 3/8-24 studs. The four-piece set fits Polaris Ranger, RZR and Sportsman models as well as Kawasaki Lakota and Tecate quads when the year, make and model match the listed specifications. Builders who need a different bolt pattern or stud thread must choose another kit.

Billet Aluminium Durability Under Load

Each spacer is CNC machined from aerospace billet aluminium and anodised to resist corrosion during sustained off-road use. Heat-treated 10.9 grade carbon steel studs maintain clamping force through vibration and impact without stretching. The cone-seat nuts seat securely against the wheel face for consistent torque retention over long rides.

3/8-24 Stud Thread Is the Fit Gate

Your vehicle must use 3/8-24 wheel studs; any other thread pitch makes this kit incompatible regardless of bolt pattern or centre bore. Verify the stud size on the machine before ordering because the supplied hardware will not engage a different thread. No other specification overrides this requirement.

Questions about this item

How much heat do these 25 mm spacers add during long trail rides?

The spacers are passive aluminium components and generate no heat themselves; they simply move the wheel outward by 25 mm.

Do I need anything besides the supplied 10.9 grade studs and cone-seat nuts to install them?

No extra hardware is included or required beyond the 3/8-24 studs and matching nuts already in the box; you only supply standard hand tools.

Will the 131 mm hub bore fit the older Polaris 400 and 500 models I still run?

Yes, the 131 mm centre bore covers those Polaris 400 and 500 hubs as long as their bolt pattern is 4x156 and studs are 3/8-24.
