Large rear idler wheels means less rolling resistance, easier backing up and increased top end track speed. Our wheels and axle are simple, strong and ready for any abuse you can throw at it. All Big Wheels Kits come with our HELLFIRE 9" wheels. Our wheels are made out of high-strength aluminum for maximum durability and bearing support, but are equipped with a user-replaceable UHMW plastic outer ring to eliminate icing issues common with full-billet wheels. Available in a variety of anodized finishes including black, blue, red, purple, or raw aluminum.

Our offset axle offers exceptional strength while maintaining a competitive weight to stock. The combination of a high quality CNC aluminum part and thoroughly tested axle makes this strong yet trim piece run 9" wheels without hesitation. We did not cut any corners on strength but worked to remove any unnecessary material to keep the weight down.

Kit comes in 2 offset sizes. from 7.25" to 9" or 8" to 9":

The first dimension is your stock wheel diameter, and the second dimension is your desired wheel diameter.

All Offset axles are available exclusively in raw aluminum silver, no custom color options are available.
