FS: New double adjustable QA1 ProCoil conversion

[BBC71Nova]

I'm considering trying something a little different now with the front suspension on my build. I have a new in box QA1 ProCoil double adjustable, 550lb spring coilover conversion setup (http://www.speedtechperformance.com/index.cfm?ptype=product&product_id=45&category_id=237&home_id=-1&mode=prod&prd45.htm) and the spanner wrench & thrust washer kit (http://www.speedtechperformance.com/index.cfm?ptype=product&product_id=171&category_id=237&home_id=-1&mode=prod&prd171.htm) that I wouldn't be using. Retail on this kit is all over the place at 799@Speedtech and a little over 600? at the big joints I think. No idea why there is such a difference but I'm pretty sure it is the same kit. These came from Speedtech FWIW. I'll get some pics up if there is any interest.

I'd do $650 for both.

Thanks!

Hey John,

Is this for SB or BB?

Hey Jay. This kit has the 550lb springs which is marketed as the big block kit. In the pro-touring arena I see some running heavier springs so they might work for other combos. I'd defer to the "experts" on what springs are better for what applications.

Bump. Need to get rid of these so I can get new setup in before car leaves fab shop.

Is it the 550lb spring rate that's the issue? I might be able to source some lower spring rates if that will help.
