Hamilton recommends 110 with their 188/220.

He told me 60's would work fine at the RPMs I turn. I don't take my truck over 3k-ish though.

I was at one of his seminars. He recommends it but said you can get by with 60's if you don't hit 4k. Most of the guys there were pullers and a few of us were drag racers.

I've drag raced and not went above 4k.

I think alot of people would be suprised if they compared all these "heavy duty" springs with a tester.

Taco, I have drag raced and missed a shift. With the 4k rpms spring, it went to 3800 really quick...

That was without core. I jumped a tooth on the ip gear and have the pump set between factory and the head right now.
