Brand new set of springs from Performance Springs. These are the second generation spring after they revised them a couple of years ago. Selling as the engine builder says the coil bind tolerence is too small for my 10.5mm lift cams. These would suit anyone with lift of 10.0mm and below.
Specs are: O.D. = 1.010 & I.D. = .735 Seat Press1.310 = 73Lbs & Open Press .930 = 140-145Lbs Coil Bind = .855
