RockTrix RT103 12x7 ATV Wheels

The RockTrix RT103 is a set of four aluminium wheels built for ATVs, UTVs and side-by-side machines that run a 4x156 bolt pattern. Each wheel measures 12 inches in diameter by 7 inches wide with a 4+3 offset and a 131 mm centre bore. The pack includes four centre caps, sixteen 3/8"-24 spline lug nuts and a matching socket key.

4x156 Bolt Pattern with 131 mm Centre Bore

Fitment depends on matching the 4x156 bolt pattern, the 131 mm maximum hub bore and the 3/8"-24 wheel studs on the host machine. Verify these three figures against the vehicle specifications before ordering, as an incorrect pattern or bore will prevent safe installation.

Riders Replacing Steel Rims on Compatible Polaris

These wheels suit owners of listed Polaris Sportsman, Ranger, RZR and Ace models who want a lighter single-piece aluminium rim and have confirmed the 4x156 pattern, bore and stud thread. Buyers whose machines use a different bolt pattern, a larger centre bore or a different stud size should look at other wheel sets that match their specific hub geometry.

Questions about this item

How does the 4+3 offset change the track width on my machine?

The 4+3 offset places the mounting surface 4 inches from the inner bead and 3 inches from the outer bead, pushing the wheel outward to widen the stance compared with a deeper offset.

Will the 4x156 bolt pattern and 131 mm centre bore fit my hubs without adapters?

Yes, the wheels use a 4x156 bolt pattern and a 131 mm centre bore, so they bolt directly to hubs with the same pattern and a bore no larger than 131 mm.

What hardware is needed to mount the 12x7 wheels securely?

The set includes sixteen 3/8"-24 spline lug nuts and one 6-spline socket key; valve stems are not included and must be supplied separately.
