I have one set of BNIB ground control springs (2). 12" length, 300 lb 2.5 I.D.

80bucks. they are 80 shipped EACH.

I also have a set of 300lb 6in. 2.5 I.D. springs, also GC, used but carries lifetime warranty against sag or breakage, or spring rate change.
these ill let go for 40.

Both are OBO.

I bought the 12" ones because my car (as pictured below) was slammed to its nuts. the 12" were too long and now im driving a truck and have ordered a set of 9" ones.
