RockTrix 50mm 4x101.6 Spacers

These RockTrix wheel spacers are 50mm thick aluminium plates that bolt between a 4x101.6 or 4x100 hub and the wheel. They widen the track by 50mm per side and are supplied as a pair for one axle. The hub centre bore is 68.5mm and the included studs use M12x1.25 threads.

Golf cart and ATV owners with matching bolt pattern

They suit golf carts and ATVs that run a 4x101.6 or 4x100 bolt pattern, have a centre bore no larger than 68.5mm and use M12x1.25 wheel studs. Vehicles with a larger centre bore, different stud thread or insufficient fender clearance for the extra 50mm should look at other solutions.

Pair with existing wheels and shorter studs

Installation requires standard tyre tools and a torque wrench. The spacers need the vehicle’s original studs to be shorter than 50mm; longer studs must be trimmed before fitting. The anodised billet aluminium construction resists corrosion while the 10.9 grade steel studs handle clamping loads.

Questions about this item

What hub centre-bore size must my vehicle have for the 68.5 mm spacer to sit flush?

The spacer’s hub centre bore is 68.5 mm, so the vehicle’s centre bore must be 68.5 mm or smaller for a proper fit.

Will my existing 12x1.25 mm wheel studs work with these spacers?

Yes, the spacers use 12x1.25 mm threads, but your current studs must be shorter than 50 mm; otherwise they may need trimming.

How can I confirm the spacers are torqued correctly after installation?

Use a torque wrench to tighten the supplied 10.9 grade studs and cone-seat nuts to the vehicle manufacturer’s specified torque value.
