Also Available While Supplies Last: QU40050U Used Spicer Tapered Hub Spring
The large, inboard end of QU40050 Spring rests against QU40035 Cupped Spring Plate. If the plate is damaged, replace it at the same time you replace the spring. QU40035 cup-shaped plates are often installed backwards which will ruin the plate and outer wheel bearing. Install the plate so the FLAT side is towards the spring!
The free length of these new springs is about 3-11/16" (+/- 1/8"). Most used Springs are shorter as they have weakened over time.
Spicer factory hubs have been out of production for decades. They were probably the strongest internal mount lockout hub ever made, but unfortunately most parts for them are long gone. As of December 2011, we still have these parts in stock: QU40154 Hub Cam, QU40558R, QU40559R, QU40560R, QU40561R (Hub Gears), QU40374U Hub Dial, QU40032 Axle Shaft Snap Ring, QU40050 Spring, and QU40035 Spring Plate.
