hey guys, do you know what type of spring i would need to bump up my engagement. i've got a white epi one now and the eng is 4800 i want something with a little stiffer initial rate with the same final rate? thanks!

i know the spring rate on the white is 125-280, is there anything i can get with a higher inital? the 280 is fine for fully compressed.

An EPI black is 145-280.......yes, it will increase the engagement but I have no idea how it will effect the overall performance of your sled. Maybe someone will have some specific suggestions for you.

4800 rpm is pretty high already. Why do you want to raise it even higher?

 

[92XCR440]

the newer xcrs engage at like 5500. i want more holeshot i dont think the little engine produces enough power at 4800.

The newer 440's need the higher engagement to get going the older fuji's don't but anyways you could get a polaris almond/gold 150-290

arctic cat spring are different, and the weights also change the engagement. i put a new belt on my sled today and it fixed the problem no more bog thanks guys
