PAC 1222X springs - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Is anyone else using these? I just got them after 2 1/2 months backordered and am anxious to get them in. Just hit 20k miles on the .660 BTR springs on an SS4 cam. This set is exactly what GPI recommended but I was just curious and wanted to see if anyone is/has ran them.

I'm using those springs in my engine with the SS1 Cam. So far so good with like 7k miles on them. My lifters are pretty noisy though but I don't think it has anything to do with the springs. I think that it's just the lifters there self (gm performance lifters).

Do you think you can get more than 20k miles outta them?

I'm not sure about that. I would call TSP and ask them cause that's where I bought mine.

What lifters do you plan to run? GPI is very technical about their setups and kits. You will be fine with those springs, no problem.

Hey Martin, I am still using the GM performance lifters that GPI installed.
