Why American Force Powersports 4x137 Wheels Matter
Powersports machines see hard loads, heat, and impact, so wheel construction is not a cosmetic afterthought. Each K-series model here is built as a monoblock forged wheel, which means it is machined from a single forged blank rather than cast or assembled from separate pieces. That approach is what gives a forged powersports wheel its strength-to-weight character and the crisp, deep-concave face American Force is known for. If you want to see how the family fits together, browse all American Force Powersports wheels for the full picture.
Models & Finishes
Eight designs cover the 4x137 fitment: K01, K02, K03, K04, K05, K06, K07, and K08. The K01 through K06 designs come in both BLACK and POLISHED, while the K07 and K08 are offered in BLACK. Prefer a uniform blacked-out look across your build? Compare the dedicated Black American Force Powersports wheels collection.
Fitment Coverage
These wheels are drilled in 4x137, a bolt pattern widely used across UTV/side-by-side platforms. The same K-series models are also produced in 4x156, so if your machine uses that spacing instead, see the American Force Powersports 4x156 wheels page. Diameters run 20, 22, and 24 inches — pick your size with the 20" American Force Powersports wheels, 22" American Force Powersports wheels, and 24" American Force Powersports wheels pages. Always confirm the bolt pattern, diameter, and width your vehicle calls for before ordering.
How to Choose
Start with your bolt pattern — confirm it is genuinely 4x137 and not 4x156. Next, pick a diameter: 20-inch keeps more sidewall for trail comfort, while 22- and 24-inch sizes deliver a larger, more aggressive face. Then choose your finish: POLISHED for a mirror-bright statement or BLACK for a stealthier build. A great starting point is the K03 4x137 22x7 in POLISHED. If you lean toward 4x156 examples, the K01 4x156 22x7 POLISHED and blacked-out options like the K02 4x156 22x7 BLACK, K05 BLACK, K07 BLACK, and K08 BLACK show the styling range across the family.
