Product Description

51 Series shocks have been replaced by the 5Q Series.

Rebuildable Steel Twin Tube Shock

Crafted with hard anodized internals and a zero gas pressure design, the 51 Series provides the most grip on slick tracks and the best feel of any shock. This shock excels on average to dry-slick dirt and asphalt tracks where traction is limited and also as an axle wrap up shock. 

The 51 Series features an in-house machined body with a larger inside diameter for increased oil volume for better cooling. A popular choice for many racers from dirt and asphalt in nearly every type of class, this shock gives superior feel and grip.
