I have been looking around for a drive spring for my 600 with slp twins and gutted air box. I am running 62 weights and almond spring. but I want a higher engagment rpm, w.o.t. is perfect. The polaris almond red has a great engagment but not enough spring at w.o.t.
I am looking for a 165lb at 2 1/2, 320lb at 1 1/4 spring. I have checked many aftermarket companys but have found nothing.

I had good luck with the EPI yellow last year. I think it was 165/310 though.

Theres a polaris black/white spring thats about 145?/320.

Have you checked Goodwin?, they have some springs with high engagement and high shift-out pressure.

I have checked goodwin, slp, aaen, polaris and arctic cat. I just keep lookin for now :cn:

Try taking 1 gram of weight off and use the almond/red. I use the Almond/Blue and had the 62s. It pulled decent but held the Rs down to much at top end. I removed weight 1/2 gram at a time. I ended up at -1 gram off the 62s. It got the Rs back up to 6250 +/- 50. That is with stock exhaust.

SLP Green/Pink is 160-340

Bull

 

[bulldogger]

EPI has a Maroon at 185-320

I know neither one I have mentioned is exactly what you are looking for but they may be worth trying. :dunno:

You cant change the engagement rpm and nothing else. Your midrange shift will be slightly different. Just keep that in mind. I'd run the almond/red and a bit less weight. It will make for a snappier setup, IMO. FWIW, my buddy has a 600 with SLP twins and hes running 60s at <1000'.
