This is a Custom Dynatrac Free-Spin™ Heavy-Duty Hub Conversion Kit for 2005-2014 Ford F-250 and F-350 Super Duty axles. We have replaced the 60 tooth tone ring with a 48 tooth tone ring to match the rear of the 11-18 GM 2500 and 3500 rear axles.
The kit is designed to replace the factory unit bearings with fixed spindles for superior strength, and smooth performance. This kit fits both single-rear-wheel (SRW) and dual-rear-wheel (DRW) trucks, and it includes Warn locking hubs.
Free-Spin Hub Conversion Kits include these features:
- Heat-treated chromoly spindles
- Top-quality bearings and seals
- 35-spline ,1.50-inch outer shafts
- Wheel hubs
- Warn locking hubs
- All necessary studs and hardware
