Dale, was the shock part # 630001 from Prevost? I just ordered two and they were about $38.50 each. Add $5 or $9 for the rubber bushings, depending on if you get the one or two-piece versions. I ordered both types, so I’ll let you know how they work out.
Before you start removing the shocks, note how many threads are showing so you can tighten the new ones back to the same point.
Using a pry bar can help remove the old shocks, and you can press on the eyes of the new ones for installation. Soapy water can make sliding the new shocks on easier.
Have your VIN ready when you call.
