Review on GMRCK25 Suspension Enhancement System by Timbren by Jason Khadka

These were added to our 2000 k2500 single cab. Sometimes we tow our tractor, hay or pickup onto our 6 ton trailer. Before that, we were bad at shooting from a slingshot. reinforced back. Saved it from sagging as described. I also screwed an extra distance to it. Fits about 1/2 inch of the case. With no load it still runs perfectly.
