Wow. That is cheap.

interesting

 

L61 compadable? No 2.2 love?

 

did u read the link?

 

no he probably didnt .. he's more fail then fail itself

 

Damn I wish I was near ZZP. Thats a hell of a deal for ~$500 installed!

 

Ah ok. Didn't read the red. Only saw they said in the main body it's for the lsj and le5...

 

Supertech uses a dual spring. The outer spring is similar to stock but made slightly larger with thinner wire. It's pressure is about the same as stock. This allows them to put a small inner spring around 20# in there to increase pressure. The downside is the loss in clearance, the supertech's will coil bind at .455 lift (not an issue for most).

ZZP had a custom spring made to replace the stock unit. Our part has stiffer coils to increase weight which eliminates the need for a center spring. with a stock retainer ours bind at .450 and with optional retainers .475

 

i'm guesing this is what you guys run on your cars?
