had been looking at the PRG leveling kit for a few months and tracking the price, hovering around $200 - 260. noticed the RTZ kit for $91 on Amazon one night whilst clicking random stuff on my phone, and boom I ordered it.
3" polyurethane front spacer
2" rear shackles
Note: I prefer rear shackles to riser blocks with u-bolts. it seems to me that adding a spacer between the axle & spring seat will increase the tendency to "roll" the axle, thus turning the leaf springs into s-curves under acceleration/braking. Longer shackles just lift the whole rear end up away from the frame attachment point, without changing any suspension geometry. :nerd: So I went with the longer shackles here.
Installed with my buddy, took about 5 hours and 6 beers, working at a relaxed pace. I really enjoyed taking the front end apart to see how this is designed. based on all the race cars I've worked on, this appears to be a very burly suspension system, as it oughtta be!! >
Now the truck sits nice an high (but not too high.)
Drive quality was not affected in any way I can tell. this is my daily driver, and it handles just as well as ever. Negligible difference to mpg economy.
