I have them on an 18' Mountain Cat, Love them, work as advertised, hole shot stockers all the time, pull a little harded in the mid, same on top. Mine has the white spring with red stripes as recomended for my alt. 3-6000'. Best after market weights PERIOD!!!!!!!!!!

What the combo in the weights are you using? I'm loaded short screw and weight in tip, super short screw in the middle. weight is 78 total. was pulling great until I hit 4500K-5500K, only pulling 7800rpms

5-7k you can use the stock spring.

Pull much harder off the bottom through the mid. Top end is about the same.

We have quite a few customers in that elevation range.
My white/red spring broke, only 500mi, do you recommend replacing with that same spring or running the stock spring?
