My max dia. is 1.625 installed height 2.000 i need 300 -310 on the seat . cam 778 in and 748 exh. i was gonna buy the k1000h's and shim the about .050 to get around 300 on the seat. mike at muscle seems to think i need to use a k1400 that installs at 2.200 and jut install it at 2.000 any one else know of any springs to use. need some quick help. thanks

 

PAC1324 comes in at 275 on the seat. Just an option.

 

I'm not a big K-motion fan. Their processing seems to have fallen behind compared to PAC and PSI... even manleys springs.
