Formerly sold as: ATV Wheel Adapter 4 Lug 137 To 4 Lug 137 (Pair) · SKU 4137-4137R-15
This type of spacer is used for 4 lug 137mm bolt pattern ATVs to fit 4 lug 137mm bolt pattern wheels. CNC machined billet aluminum. New wheel studs are included.
Our premium quality spacers ensures durability and strength. Price is for a pair (2 spacers).
**If the hub studs protrude outside the spacer and prevent the wheels to sit flush on the spacer plates, it is required to shorten the factory studs. It happens most often on 1" thick spacers.
Fitment and specs
- 4x137mm on both sides: bolts to your 4x137mm ATV hub and carries your existing 4x137mm wheels
- Same-pattern design works as a spacer, adding track width for a wider stance
- CNC machined billet aluminum
- New wheel studs included
- Sold as a pair (2 spacers) with free US shipping
Make sure each spacer sits flush against a clean hub face; if the factory studs protrude past the spacer plate, shorten them so the wheel seats flat, which comes up most often on 1 inch thick spacers. Torque the spacer fasteners to spec, then the wheel, using our torque reference chart. Re-torque after the first 50 to 100 miles.
Common questions
Why buy an adapter with the same bolt pattern on both sides?
It works as a spacer. The plate pushes each wheel outward, adding track width for a wider, more planted stance while your original 4x137 wheels bolt right back on.
Are wheel spacers safe?
Yes, when installed correctly: seated flat against the hub, torqued to spec with full thread engagement on every stud, and re-torqued after the first 50 to 100 miles.
