Red Upgraded Spring For 40 Series...
I have a 16 HP and at idle you could not stop it. I installed the red springs. Help a bunch. I went ahead and ordered the medium weights after the fact. That is the ticket. Works awesome.

Red Upgraded...
Once again Go Power Sports come thru for me!, I wasn’t able to get the rpm down on my Predator 420, so my drive clutch would still be engaged enough to always make it creep at idle, but with the new upgraded springs from Go Power Sports solves my problem! Thank you!!!

Go...
This is the second set of red springs I have installed in this setup. I had a spring break after about 8 months of use. I ride my buggy a lot, sometimes at the beach where we ride around 45 miles in one afternoon. We ride slow quite a bit and these springs keep it in low range for easy riding in the sand. I also set the spring on the driven pulley to come in later for this same reason. Red springs all the way!

Red upgraded 40 series springs
They did exactly as advertised. My tach reads 2150 rpms when it just starts to engage. Makes riding my Chinese Buggy with my hopped up 460 cc engine a blast.
