I bought some napa front springs seeking out V8 ext springs. I found Napa has a few different ones available.

Height wise they have the same load height, but there is a major difference in load design. I see the coil type with square end and Tangential end, whatever that means. Im guessing its in LBS

Has anyone used these? I bought the Napa 2773484 hoping more weight means less compression and will add some ground clearance. Im waiting on getting my spacers for the fronts before doing this as I dont want to do the work 2 times. If i get OE 88 springs I will just return the Napa ones.

Coil Spring Free Height : 16.74"

Also I just Installed 08 Tahoe rear springs. #2773522 Napa and it added 2" easy.

The rear wheel well measuring heights

Front of wheel 11.5" rear of wheel 14" Before measurements.

AFTER Front of wheel 13.5" and rear is 16".(edit, seems closer to 14 and 17 inches.I think the lower front made things off. I will have to see what happens when the front gets evened up. I feel like Joe Dirt driving this thing)


Im sure there may be settling involved, but so far so good. Now it looks odd with the front Stock springs lol.

baby steps
