R&P Knowledge Hub
Straight spindle torsion axles differ from traditional tapered spindle designs by using identical inner and outer bearing sizes. This hub uses 25580 bearings in both positions, which is uncommon in 8K brake hub configurations. Installing a tapered spindle hub on a straight spindle axle will result in improper bearing fitment and unsafe operation. Always confirm spindle type, bearing numbers, seal dimensions, and casting numbers before ordering.
