I think that one of the things missing is that if using 2 identical springs, the will both collapse at the same rate and the rate does not change. The only way to make it dual rate is to add a limiter to one spring. Both collapse at the same rate until one spring is limited then the rate becomes the spring that is not limited.
What is considered too much pre load from zero or loose spring at the adjuster as a general rule? Or if you needed to put this much pre load in you need heavier springs.
Zero preload to 3/4” is not enough. Too stiff of a spring rate. 2” or more is too soft a spring. We shoot fir 1.5”. But some utv like a lot of pre load. RZR xp front likes 2”. Most don’t.
@@ShockTherapyllc so when you say 1.5. Is that from 0 or 1.5 after the first inch which would be 2.5 from 0 ? Also is there a average of difference between the two spring rates 50 lbs 100 lbs. I have a full size 4 seat buggy, 2275cc but with type 2 trans, king 2.5 coil over that is 25 years old, big car for desert. I'm trying to dial in the rear spring rate for a softer slower ride, right now they are 400 over 450 spring rate should I lower the top or bottom. Thanks.
@@timbeach2409 I can't answer your question with out the car here but that sounds like a lot of spring for your car. Here is the math. upper times the lower, divided by the upper plus the lower. That gives you the combined spring rate. You have a 211 lb combined spring rate. Jack your car up off the ground. Measure the pre load collar location. Raise the collar up till the spring just begin to rattle. Measure the collar again. The difference between those measurements is your actual pre load. Under an inch is too stiff. More than two inches is too soft. Adjust from there
hey guys, i just bought a yamaha rmax 2 xtr. jusr noticed on the front suspension that the top coil is almost if not, completely compressed from the factory. any ideas on why they do this? there is also about 6 inches of threads left above it for adjustment. just curious. thanks.
This is common on almost all UTVs. Especially the Polaris models. This is a cheap way to stiffen the system to pass the government roll over test. It does sacrifice ride quality and why we sell some many spring kits. We are currently working on a spring kit for your UTV
@@ShockTherapyllc makes sense. and that is good news on my end! in the mean time would you recommend taking some tension off of these or just leave them be? thanks for the quick reply. you guys ROCK!
I dig this channel. Thanks
I'm going to put into practice what I learned today. Nice!!!

You are correct about cross over rings. I do it so much that I forgot to mention them
The you tube version is so much better than the live facebook version... you cut out all the gibberish. Thank you.
That’s interesting how the crossover can cut the spring rate in half... maybe we can get a technical demonstration of how that happens?
Good idea. We will get on that.
I always enjoy your streams, Ya'll do a great job explaining engineering principals. Thanks for putting in the effort to make this content!
Thank you. Much appreciated

Just ordered a spring set for my sport Xrc,can't wait to install them.
Right on! you will love them

@@zachbrannon4290 your welcome. Taking pre load off will just lower your utv. That upper will always be coil bound
