1/22/15 - Springs are usually in stock but please allow for potential 1-2 week lead times on shipments due to fluctuation. We appreciate your patience!.
Years of testing and several years on the market has proven Racer Tech has the best replacement spring option for the RZR S 800 using Fox Podium Shocks. This is a Racer Tech D.I.S.S. Dual Rate Kit which gives a substantial improvement in ride quality while improving handling as well at G-out resistance. We've found the perfect combination of spring length to rate ratio and are very happy with our results. This kit is for all four corners of the machine. It provides a short spring, a long spring and a delrin spacer for each shock. The secret is in our short springs. We've found a perfect universal rate which allows us to custom tailor our long springs, (which determines the final rate of the suspension) to each individuals needs.
This is as good of a question as it is common. Dual Rates are essentially the same as any progressive spring in the sense they achieve a similar goal; they vary the final rate at different compression heights. The biggest difference for the end user is the adjustability gained by choosing the dual-rate. Our options are limitless with this setup and more variations are made up and applied every week to suit customer’s individual needs. With dual-rates we are able to "fine-tune" your ride in a way that was previously not possible. Another more technical reason why we at Racer Tech prefer dual-rate springs is they are able to reduce excessive rebound issues which are extremely inherent with the RZR's. The OEM believes in using light spring rates with unusually large amounts of preloads to achieve their desired ride height and ride. We believe in the more commonly accepted method of using properly matched springs with less preload. This allows the spring to work the way it's designed to better because we aren't so far into the compression. This reduces the spring tension which in-turn reduces the requirement for stronger rebound dampening, which in-turn causes less work for the shock, which in-turn causes less friction for the fluids, which in-turn extends the time it takes for the fluid to overheat which of course is the catalyst in the equation that makes shocks "fade". This is very good for the potential customer who doesn't really ride aggressively enough, or often, to justify spending the big money on a set of aftermarket shocks. By creating a lower initial spring rate when both springs are active there is a much lower resistance energy which is what ends up giving the RZR it's "bucking" effect. The three major elements that sets the dual rate kit apart are: Predictability, Consistency and Adjust-ability. They've proven multiple times to handle better through better stability at speeds and help the driver to know what to expect out of the RZR in different situations. They also give the end user the option to fine tune the ride and handling by simply switching out the long springs for a fraction of the cost of buying a full new set.
Some may say we have created an unorthodox dual rate spring system here and they would be right. We believe there’s more than one way to go about things as do most people. The truth is, we’ve developed a theory after years of knowledge and experience combined which works very well for this specific application. We’ve found a new combination of spring rates and a new way of applying them to achieve a better ride and better handling than anything else currently on the market. There are people who have tried other alternative springs out there who are coming to us for a better solution and we are proud to say we have it.
While it’s rather uncommon, we've managed to break a several of the OEM lower spring retainers during extreme driving. Due to this, Racer Tech has designed custom billet retainers which substantially improve on the original design by increasing the cross sectional area of the part as well as employing much better materials. All Race retainers are gold anodized. If this upgrade is selected, four of our Race Retainers will be added to your order. To use them you simply substitute the new retainers for your old ones when installing your spring kit.
For the ultimate performance from the OEM shocks, add these springs and contact G Force Racing Technologies in Tennessee for revalving. These guys have been working a TON with racers in UTVRR and us at Racer Tech to develop the best valving solutions available for the RZR XP 900. They are VERY accommodating and can help you get your machine doing exactly what you expect it to. With these springs and service from GForce there is no reason to spend money on aftermarket shocks unless you need custom lengths or if you are running hard enough to over heat the OEM shock fluids frequently.
"It's hard to say what's the best when you've only tried one. At Racer Tech we believe we have the best spring replacement kit in the world and are willing to put our money where our mouth is. If you have a competitor’s spring kit and want to try ours, buy it. If you don't feel our springs are better than what you have you can send them back for a 100% refund."
This kit is 100% MADE IN THE U.S.A. and we at RT are VERY proud of this!
Kit includes (8) springs and (4) spring spacers. All springs come with silver powdercoat.
Here's a GREAT video testament to show how the Racer Tech Dual Rate spring design works in different scenarios. The proof is all right here and there is no other spring package in the world that can do what these do! Watch closely and see how the two springs almost seem to talk to each other to control and regulate which spring moves first based on the impact and the speed of the cycle.
Medium - The medium rate set is a perfect improvement over stock for recreational drivers without very much extra weigh added to the vehicle. The medium rate is perfect for the moderate to aggressive driver, intermediate racer or for a vehicle with some extra weight in accessories or passengers. Of all the options this seems to be the most popular and seems to work the best with our Racer Tech Lift Kit.
Heavy - The Heavy option if for the drivers who are carrying more than the usual amount of payload on or in their machines. Heavy roll cages, bumpers, winches, tools and gear all weigh the machine down and if you feel like your machine needs just a little more spring to hold it up than the other guys then this option is for you. This kit when combined with a Racer Tech lift kit will make for a very stiff ride. We recommend the customer considers this before ordering this combination.
Of course because we can make all the adjustments with one spring per shock, we are able to sell individual long springs to people looking to "tune" there springs sets in to their specific liking. We will list the two standard packages which will cover about 90% of all users. If you would like to discuss a custom combination feel free to call and an engineer can help you find what you need.
Here's a great installation video from our friends at Mud and Guts Offroad.
