This is a true dual-rate spring kit with adjustable crossover collars from Schmidty Racing Suspensions for the Polaris RZR 900S and 1000S (2015-current). Kits are available for either 2 or 4 seat models. These kits feature top of the line Swift brand springs which replace the low quality / saggy / poor riding OEM springs.



This kit will only fit the Fox Performance 2.0" aluminum bodied shocks that came standard on the RZR 900S/1000S. This kit will not work or fit Walker Evans shocks.

With our dual rate spring kit you can expect to:
  1. Regain lost ride height.
  2. Receive a truly plush ride eliminating most of the trail chatter feedback you get from embedded rocks, ruts, tree roots, tire tracks, etc. with the lighter initial spring rate of both springs active.
  3. Superior bottoming resistance when the spring separator contacts the crossover collars and engages the heavier main spring solely for the remainder of the shock stroke.

The beauty of this kit is that it is truly adjustable! The threaded crossover collars can be infinitely adjusted "up" or "down" on the shock body thread, to set the point in the stroke where the spring separator contacts the cross-over collars and engages the heavier main spring solely for the remainder of the shock stroke. Either hardware style of our spring kits are totally user friendly and require no shock modification to install. Installation only requires basic tools and 3-4 hours time. Our dual rate spring kits come with a detailed and complete, step-by-step installation instruction sheet with settings, diagrams, and photos.

    Hardware Includes:
    • (1) Custom Tailored Installation Sheet
    • (8) Billet Adapter Rings To Convert from 2.25" to 2.5" Springs (No Plastic Adapters Like Others Use Which Crack)
    • (4) Upgraded Spring Separator / Sliders
    • (8) Threaded Locking Crossover Collars
    • (8) Quality Swift Springs (4 tenders & 4 main-springs)
    • *Each kit does all four (4) front and rear shocks

No Complaints

The springs were high quality. Installation was easy, it does take some time to get the right ride height etc. I felt the instructions could have been done a little better. These instructions didn't exactly work for my shocks but I figured it out. Delivery was very fast. Packaging was good. So in the end I am happy with the product.

Great Value

I have a 2015 two seater RZR that rode rough, sounded like a truck in the rear and I couldn’t keep up with anyone. I Replaced the springs, reservoirs and bought a kit to fill my own shocks. I can’t explain how awesome my RZR rides. Over the washboard in the desert it’s smooth and just flys like it never has ever been. These folks know what we need !

Reliable Performance

Instructions were easy to understand and follow. Made a huge difference in how the 900s handles compared to the OEM springs. Good quality products.

Perfect Ride Quality

I was initially skeptical prior to installing these on my 900s Fox shocks. It wasn’t until I had removed the old coil springs and compared to the new coil springs when I realized “oh man these things are shottttt!”. Thanks to the guys Taylor and Evan at Schmidty Racing for helping me select the right coil springs for my rig and getting them shipped super quick! I will be a life long customer!

Big Gains in Comfort

Evan was very helpful with choosing the right set up with my springs. Easy setup with the race setup. Easy direction for the install as well. Wish i could give more stars.

Clean and Controlled

I’ve only had my suspension back on my Rzr a couple days and I can already tell that it’s 100% better than factory. The instructions were pretty good and easy enough to follow. I would most certainly recommend to others.

Really Impressed

I got the heavy spring rage and the shocks are to stiff. ( my fault, I should have done more research) Rode them one and called to ask for help in some way 4 times. I can’t get a call back and I am feeling unhappy that I spent $1600 Canadian on a product I have no support for.

High Performance Setup

Excellent product, easy install. The look and finish of this product is top notch and not only improves the ride, but improves the look of the machine as well. Would highly recommend!

Better in Every Way

I recently decided to swap springs instead of just putting a band aid on an already shot suspension. Haven't had a lot of riding time since but it's a night and day difference from the short test drives. Relatively easy task and thorough instructions made it a simple swap.

Much Improved Ride

Night and day. Before adding these my machine was louder, clunkier and not a great ride. Following the instructions I was able to add these and what a difference. Such a much smoother ride. Very happy with the purchase, well worth the money.

Very Dialed

Love my new shocks, very reasonably price. took my 2.0 factory fox shocks and revalved, rebuilt, new Eibach dual rate springs with cross over collars and high capacity end caps on the reservoirs. Great customer service, called a couple of times and Evan was very patient and explained everything to me on how to adjust the compression. everything is great, I'm having a great time riding in the so Cal deserts.

Great Ride Control

Finally got rid of my old saggy springs. Gained back my missing 2” of ground clearance in the rear. Ride quality is greatly improved. Less body roll going over obstacles and more suspension travel instead. Every thing set to there recommendation. With lots of room for fine tuning.

Awesome Upgrade

I purchased the standard kit for my 2015 900 s and couldn’t be more pleased.the ride hight has been restored to the original specs as well as improving the ride quality .i would also like to thank the friendly staff for all the help answering all my questions.

Handles Rough Stuff Easily

Evan was very helful, imformative, and patient when I talked with him on the phone- nice guy! I chose the medium springs with race hardware and I am very happy with the results- Evans recommendations for preload and crossover seem to be right on for 2 150 lb people and a minor amount of cooler/gear. What an improvement in handling and rip-ability! Much better ride in all situations! Thanks Evan!

Smooth at Speed

Purchased your dual rate spring kit because I did like the factory setup in the rear with the upper spring fully collapsed all the time. I figured I could get a better ride if both springs actually worked. After installing a set of your trail springs I was amazed at the difference in ride and control that I have. I live and ride primarily in northern Wisconsin and ride wooded trails that are twisting and filled with pot holes and rocks. Your spring set smooths out all of that taking away the harsh jarring that I would get with the factory springs. Allows me to ride faster with more control through the trails. Thanks for coming up with this awesome upgrade.

Noticeable Gains

Excellent Product, great instructions, was worried that I wouldn't be able to obtain my desired ground clearance of 14 inches as my RZR is quite heavy. Ground clearance was no problem, added extra 3/8 inch pre-load in front and an extra 1 inch preload in the rear. Have plenty of space in between coils of tender springs front and rear. Ride smoothness is 300% better. I chose the (heavy) kit based on Evan's recommendation - perfect choice - I very highly recommend Schmidty Racing's products!!!

Super Happy

I ordered the Heavy Duty Race springs. I now have all of my ground clearance back, no bottoming, no matter what I drop into and they always come right back to their original length. In hindsight, I probably should have gotten the Mediums, but, I would rather have a stiffer ride than to go back to bottoming out and with the Heavy Duty, I'm set for whatever and whoever I have in the buggy, no matter what the terrain is. Schmidty sent exactly what I ordered and it came right on time. I wish for the price of these things that they would include the billet wrenches, but, it isn't a big deal to order them after the fact. Still, IMHO, these are the best out there.
