Comp 987's vs 978's
 
I was looking around and font these springs and just wanted to know if anyone had the specs on them. I thought they only made 987's but guess not. Anyone running these. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

978 produces 150# seat load at 1.800 and 400# @ 1.200. Can be used to about .600 lift with this installed height.

987 produces 130# @ 1.800 and 325# @ 1.250. Can be used to about .590 lift.

Larry, any comments on the Isky dual spring (1.430")?

I'm wondering how they stack up against the comp 978 spring.

thanks
