After years of testing, development and several years on the market, Racer Tech has proven to have the best replacement spring options for todays UTV's. Now we are happy to release the newest option for the RZR XP 1000 using OEM shocks. This is a Racer Tech D.I.S.S. Dual Rate Kit in the front 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 as well as adapters for the front shocks to run 2.5" springs.
The XP 1000 is a completely different animal. It's suspension works unlike any other model in the past and unfortunately we don't think it works very well! The rear end lifts hard when braking and does not reset when getting back on the gas. This makes the RZR very top heavy in the turns and can cause a "two wheeling" effect which ultimately ends up in a roll over or at least, very slow and boring performance. Another inherent negative is the dreading "bucking" effect all RZR's are known for. No matter what the OEM says, it's still very apparent in the RZR XP 1000.
Racer Tech worked with G Force Suspension Technologies for over three months testing countless spring variations until we had something perfect for the front using our D.I.S.S. technology. Then we determined we would need to completely redesign a rear system to work with this models unique characteristics. The result is the kit you see here. It cannot be rivaled by any other kit on the market for it's price or performance. With this kit, the XP 1000 squats and grips at the exact moment you expect in a corner, every time. The amount of control these springs give the RZR is incredible. Due to so much travel the car feels much like a trophy truck with this kit but once the shocks are adjusted properly and the driver gets used to the handling the car is a completely new machine. The bucking is all but eliminated as well.
In his first outing with the production Racer Tech RZR XP 1000 spring kit, G Force valving and an otherwise completely stock car, Professional G Force / Racer Tech driver Jamie McCoy took 1st overall in UTVRR North Round 9 on 11/9/13 in Windrock, TN. Additionally, Jamie set a new course record by nearly 30 seconds! This was done with nothing but the Racer Tech dual rate kit available here and G Force valving.
The spring kit alone will make a night and day difference in the performance of the RZR. This is enough of an improvement most recreational driver's will never need to make any other internal adjustments to the shocks and will be able to fine-tune the ride with the external adjustments provided on the OEM shocks. For the customers wanting more, contact G Force suspension Technologies for custom valving. Note: Racer Tech does not offer valving service nor do we handle the shocks for G Force. For revalving services please contact them directly!
The kit was designed to lower the car at minimal preload. At minimum, the car at OEM weight should sit around 11-12" measured from the bottom of the chassis. However, since there is so much adjustment available on this kit is is easy to still maintain 13-14" of clearance by simply adding more preload. This kit will work for almost any RZR XP 1000 no matter the setup. If you have a very light machine you can run minimal preload. If your RZR is loaded down with accessories and cargo most often simply turn up the preload until you achieve the desired ride height.
This kit is 100% MADE IN THE U.S.A. and we at RT are VERY proud of this!
Kit includes (8) springs, (4) spring spacers and 4 front spring adapters. All springs come with silver powdercoat.
Why Dual Rates?
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 Commander. The OEM believes in using light spring rates with unusually large amounts of preloads to achieve their desired 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 Commander 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 machine 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.
"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."
