I'm installing my Hyper flex bushing kit, 2" leveling kit and Edelbrock performer IAS shocks tomorrow! First upgrades to my '03 Silverado. My tires should come be here in about 1 week. (LT265/75R-16 Michelin LTX A/T 2 E) I'm also waiting on my steel braided brake line and ceramic pads, should be here in another week.
Tried to replace the stock leaf spring bushings with Hyper Flex Bushings and it turned into a total nightmare. The bushings that hyper flex gives you DO NOT FIT. I had to bend the leaf spring shackel to fit it back on and then had to saw off part of the bushing on the leaf spring it self, to get it to fit back on the truck.
The new Edelbrock IAS shocks I installed made a huge improvement over the stack shocks. No surprise their. Body rolling in turns was significantly reduced.
