Default Z-51 suspension ???

Could someone explain what the differance is in a Z-51 suspension and a standard suspension on the 85 and would they both use the same leaf spring.

Thanks
Don

No, it is definitely not the same spring. That is the major difference.

Suspension wise it entails heavy duty bushings and stiffer shocks, as well as a big increase in the spring rate.

The two are interchangeable though, and the ride quality will go up with the softer spring.
