Polaris RZR XP Turbo (2017-2019) Race Rack & Pinion (Long Pinion)
After running with a "stock" rack and pinion in our XP Turbo shop with 32" tires, we simply didn't see any reason to change. We didn't have any excessive wear or rattling, even after 1,500 miles of racing the support But then, as we ran our next race, Discovery 800 UTV Parts, 2009 Big Muddy UTV Parts, BOOM, Coleman UTV Parts, we lost all the. steering and we finished After a post-race inspection we found that the factory bracket had collapsed in half, right in the center of the splined rack gear, allowing one half to pull on the! right side and the other half pull on the left side of the rack body.
No problem, we thought, just order a spare replacement from anyone and it must be better, right? No, so fast the aftermarket replacements used gears.rack that were just 0.085 inch thicker in the same place our rack had broken in half. These brackets extend the width of the tie rod pivots by up to half an inch. It's really bad when you change the wi. With these pivot joints you add bump steering to your front geometry. This means that as the suspension moves up and down, the "toe setting" changes a bit to toe in, toe in, or both. This gives you nasty feedback in the steering wheel when you hit rocks or whoops, which takes a toll on your arms and hands, sure, but the real damage is to your front joints, bushings, ball joints and bearings. The lifespan of these parts is seriously reduced if your car has dents. Another major drawback of Bump Steer is that the car is constantly trying to "hunt" for a direction to go. As tires changetip, the direction of your car also changes. Every time you hit a bump, scream or jump and hold the steering wheel straight, the car will seek direction by pulling left or right alone. This feeling is unnerving in a gaming car, but downright dangerous in any racing car. So we kept looking for another mount and found the only billet mount on the market. We bought it and loved the large uh, international utv parts, square rack gearing and custom tie rods, but when we measured the width of the tie rod pivot points we found that they were 1 1/2 inches too wide! Would that create more than 3 inches of steering hump? Wow, I can't run that. Having no other choice of supports to purchase, we were forced to make our own Race support and here is a list of the items we put in our supportort Race and which you will not find in any other medium!
1 . 7075 aluminum construction. This high-quality aluminum is almost as strong as carbon steel and costs 3 times more than the more common 6000 series aluminum.
2. Hard anodized plating. This hardened surface not only prevents wear in the harshest environments, but also extends the internal life of the rack.
3. Lubrication of dispersed grease passages. Our UNIQUE lubricator supplies 6 different locations in the rack through a network of internal passages. Proper lubrication is the key to rack life. Some of the locations fed by the internal passages are the pinion, the rack gear on all four sides, and the vertical stress load points where the rack gear sees the most potential wear. Thanks to tight internal tolerances, you will only need to grease our racke with two pumps of a grease gun every 1,000 miles of racing during your routine preparation.
4. Huge 1" x 1" square rack gear. This massive gear is twice as thick as the original round gear at its weak point at the base of the tooth. The size of this gear prevents bending and breakage, but the material used is also 125% stronger than the original material. Another important thing about a square rack gear is that it prevents twisting. The stock round gear has a tendency to twist in the rack body as the tie rods force it up and down. This twist jams the rack in the pinion tooth. This acts like a log splitter when it forces the sharp pinion tooth into the tooth base of the rack gear and creates the "broken" rack gear problems that stock racks are known for. With our gearsquare rack gear, there is no twisting force to worry about and therefore removing all pinion forces from the rack gear.
5. Heat pre-treated rack gear. Most racks use a soft material for the rack gear so that the teeth can be easily machined into it. After the machine process, the gear is heat treated to increase its strength. Heat treatment deforms the gear by up to 20 thousandths of an inch. In terms of machine tolerance, it's a huge amount, so they try to bend it or straighten it again, but you can't straighten it to a limited extent and there are often waves in the gearing from one end to the other. This means you need to increase the clearances in the body to allow the equipment to move inside the rack. We didn't like it at all, so we took a different route. We have likeenced with perfectly straight pre-hardened material and cut our gear teeth into it. This is a very expensive process because the tooling wears out very quickly and the machine time is 5 times longer but the end result is a perfectly straight gear with less than 1 thousandth of an inch of runout.about at the end! This tolerance allows us to tighten the rack body and keep any play (which contributes to wear) in the rack to ZERO tolerance!
6. Patented gear tooth design. In choosing a tooth model, we based ourselves on the industry standards that were initially available. Through exhaustive testing and the intentional use of weaker materials to find points of failure, we found that the base of the standard tooth design was the weakest point and prone to breakage. We looked for another stronger tooth model, but couldn't find anything, so we decided toe create our own! Thousands of dollars in custom tooling later, we now have a patent-pending tooth design that has TWICE the base gear thickness as a standard system does.
7. Heat treated sprocket. Our sprocket starts as a solid piece of Chromoly 4140 material. After machining our custom tooth pattern, we heat treat the sprocket to a 60 Rockwell. It's actually harder than a carbon steel drill bit for superior strength and longevity!
8. Pinion bearings. The pinion bearing is often overlooked but not here. Normally the pinion bearing is pressed into the rack housing. This puts pressure on the bearing inward and can tighten the pinion and rack slide. We have created a new system in which the pinion bearing is not pressed but barely slides into the rack body with onlyment 1 mil of clearance. Then, side by side refrigerator parts, our bearing retainer plate has a 10 mil step that preloads the bearing vertically in the housing so that it cannot move and cannot tighten the pinion and slow down the rack function. Finally, there are many different bearings you can use here, starting at $5 all the way up to $30 very high tolerance bearings. We of course only use the $30 bearings.
9. Faster steering ratio. The factory mount features a two-turn locking system. This means that if you drive straight and put your hand on the steering wheel in the center, if you turn as far to the left as possible, the wheel will make one complete revolution before stopping. One full turn in a straight, centered line and one full turn to the right. This is two complete turns from one lock to the other. Our R rackace is a faster system. It spins the wheel just after 3/4 of a turn from the center. This means that our rack has a system of just over 1.5 turns. We tried using a higher gear, but found that the power from the electric power steering system was not enough to achieve a higher gear. The steering became heavy and cumbersome, we went back to a 1.5 turn system which is faster but still feels great.
10. High quality rod ends. Our Race Rack uses huge 5/8 rod ends for the tie rod pivots on the ends of the rack gear. We would never use inferior injected rod ends. We use only the highest quality, Teflon lined, FK JMX10-T rod ends. You'll be able to run a full Best in the Desert season on these rod tips without having toreplace them.
11. "Taper Lock" locknuts. Our patented PRod End Locknuts, called "Taper Lock," are an industry first. If you've gone shopping with rod ends and lock nuts on your spoke rods, tie rods, or control arms, you know that lock nuts always come loose. Most teams weld them in place to prevent this. We didn't want any welding on our rack gear, so we developed the "Taper Lock" system which uses a tapered machinist's tool to lock the jam nut and rod end in place. When you tighten the locknut, the male cone of the nut and the female cone of the rack gear fit together and lock like a tool collet in a milling machine or lathe. These locknuts also serve as direction stops for moving the rack. A positive lock and no release sont the only way to finish races!
12. 4130 Chromoly screeds. Our tie rods that allow you to attach your tie rods to our rack are huge. They are made from solid 4130 Chromoly and use high tolerance 5/8 diameter shoulder bolts to connect to the rack's 5/8 rod ends. The WELD on clevises feature two machined steps designed to be inserted into your tie rod tube and welded. The tube diameters for the clevis are 1" for .120 wall tube and for 1 1/4 .095 wall tube. We also offer a 5/8 threaded clevis designed to be screwed into your replacement tie rods or in a kit. long travel such as Assault, Cognito, UTV Accessories Utah, Long Travel Industries and any other tie rod that uses a 5/8 rod end in its tie rod. Finally, we also offer a longer clevis for Lone Star tie rods. get exactly what's best for your systeme of tie rod.
