Are the Prairie and Vforce primary springs compatible? If so, what performance differences should I expect upon installation? Appreciate the help.

 

yes they are compatable... Both KISSOFDEATH, & MIKEYBOYESQ, have done spring tests... I my memory is correct, the O.E. 700 spring, Dalton plain white, & EPI pink, were best trail springs... there are literally 10 -20 different springs to choose from... I believe Nyroc has a sapring chart on his website...

 

get the blue spring from dalton ind. It works great.
I would also recommend the secondary spring also.

 

Called EPI for their recommendation on the primary....they asked what size tires I had, 25", then said use pink spring. Kawituner may be right about the dalton blue because of your 26".

Don't know what EPI would suggest for your tire size. I know if you can keep from jolting your drivetrain too hard at takeoff, (pink spring is almost stock at low rpms) it's easier on the components.

 

Thanks for the help!

 

BD PM me in a week or 2 I will give you a update on another primary spring we are testing. I think it may be what the doctor ordered.
