Valve Springs
 

Whats the opinions on valve spring brands ,comp.,tool room,crane etc. for a 700 plus lift solid roller ,850 opening pressure at1.25 in. THANKS

Erson is a good spring, less money the manley and same springs.

PAC makes the best, second IMO is Manley Nexteks.

I should add to my last post, I just went through buying springs for my bb. Machine/Motor shop I got them through said that almost all springs are made at the same spot everyone just slaps a different name on them. Anyone know if there is any truth to this ?

I have had good luck with Kmotion. I would also say that Pac is the best.

PAC(Petersen American Corporation) is one of the largest spring manufacturers in the world, if not the biggest. They are OE manufacturers for most any company you can think of that use springs, from Catepillar to GM and Ford. They manufacture everything from ball point pen springs to springs used in trucking and shipping industry. Their racing arm is PAC, they do make springs for many aftermarket companies IMO they are the best spring out there. They also make custom springs for many of the top professional teams in racing. From NHRA to Nascar, F1, Rally and Sprint cars. One thing they are not is inexpensive. But then again what top shelf parts in racing are?

I agree strongly with B1valiant, I have been using them on everything since I found them. Install them and you forget about them. I used to replace a few springs during the season using Manleys nex tec and every other so called high end spring. These are the springs that last forever, NO SHT.

Disheartening......

That drunk postal worker from Cheers and his show >(made in America)< did a skit on one of them AMERICAN spring manufacturing companies, I can't remember the name of the company, it might have been PAC but man that was some neat $hit seeing how they made all those different types of springs.

Maybe they need to rename it to - Peterson MEXICAN corp?
