TR4A/5/6 Race Rear Hubs.
These hubs solve the problem of the weak point of the original IRS: The potential of breaking a quill shaft / stub axle and loosing a rear wheel. In order to use these hubs you will need to convert the outer driveshaft joint to a flange fitting. These flanges are available as a separate item.
We also offer up-rated driveshafts for competition use designed for use with these hubs.
Hubs priced as a pair.
