TSP PRC EHT Springs
Just a heads up buyers beware. Had a failure of a PRC EHT spring with less than 8k miles on it. Luckily it didn't completely drop the valve. I heard horror stories before about their springs, now I can confirm. These are supposed to be good for around 20k miles, mine were installed with the heads at 7k miles and didn't last to 15k.

They offer a one year warranty on these parts. I have had these for well over one year. I just wouldn't buy any PRC branded springs ever again. PAC or BTR from now on. I will still do business with TSP for many things as they have always treated me right.

And I am probably ordering PAC replacements from TSP through my Tuner.

I run the TSP VVT 3.2 cam, TSP PAC polished 660's with Ti retainers, TSP 1.72:1 roller rocker arms in TFS GenX 255 heads.
With those rocker arms, my valve lift is almost at 660... I rev to 6,800 rpm's all the time and during tuning my trans shifts, I have accidentally rev'd even higher. No issues in over 10k miles.

What cam do you have that makes power all the way to 7,200 rpm's?
What supporting mods did you do? Oil pump?

Blown and stroked your lucky to not be buying more than new springs, watch out for mechanical overrevs they limit the life of the spring to jack squat. The tougher the spring the more the lift unfortunately the easier the break....Have no idea what your redline is or what...but most springs are only tested to 7k...….ls7 territory

Replacing with PAC springs, TSP has contacted me and offered to make it right as well. I don't blame TSP at all.

I have a brand new set of springs from Livernois Motorsports you can buy from me. Believe they use PAC springs, PM me if interested, sell them pretty cheap, they were 400 new.
