Just finished running in my rebuilt Genesis engine (thanks Irvine) but the shocks are all sagging/ binding. I've stripped them down and the oil was fine but noticed the shock shaft is quite tight where it goes through the shock body. At first i thought the pistons were tight in the bore but its not [:@] what is happening is the seals in the shock body are very tight on the shaft causing the binding. Is there an easy fix for this as i don't want to have to replace all the seals every gallon or so. Are there any better shocks off a different rc truck that would stand the weight of the Genesis? are there better seals or shafts that i could get?
