i think most guys are running the almond spring. i am going to try the slp set up with the green pink spring and mtx 74's and see what happens

I am running the Black/Green with the 10-74's and is seems to be working great. My Polaris dealer seems to think the Alamund is kind of "old school", but others say it works!

10-74's on a STOCKER?? WoW...
At what altitude?
Your engagement RMP must be really low and you must run a heavy primary and secondary spring??

My setup for 5000 - 9000 feet 2.4" series 4 159" track, Almond primary, 3211115 belt (set up correctly), 10-70 weights, Red/black secondary (stock but new), roller thrust in place of the Delrin washer, 66-42 helix, 19-43 gearing. Maintains RPM on Deep long pulls AND works the ENTIRE face of the primary which is key to keeping the belts/cranks/clutches happy!

NOTE: SLP and Polaris spring colors are different for the same rates in a lot of cases.

I run a new spring EVERY season in the primary and secondary.. Cheap, and keeps the performance consistent... Sitting all year in the compressed position takes its toll

Almond and 10-74's for 3 to 6000 on a 975 with 7850 rpm works well for me. Stock secondary spring.
