Unfortunately for me, my last GMT400 - a '93 full size Blazer Silverado - gave up the ghost recently when the frame rotted out too badly. I now have a 14 GMC Sierra Double Cab and a 99 Jeep Grand Cherokee with a 2 inch IRO coils spring lift.
For the Cherokee, I used Pro Comp 9000 series shocks instead of the Bilstein 5100's. My decision was purely financial as the Pro Comps came in a little less expensive.
But (on the old Grand Cherokee atleast) I love the ride and handling.
I am looking to level my GMC, and have thought about the Bilstein 5100's but I'm not sure. Does anyone else have any insight or experience with the Pro Comps?
