ASSAULT RZR TURBO S

— Raiding the fast parts shelves with an employee discount —

By the staff of Dirt Wheels

Let’s say that you work at an aftermarket company that makes excellent and very cool products. Imagine that the company is Assault Industries. Further suppose that you just bought a Polaris RZR Turbo S. Tom Cavish faced this exact scenario, and he needed to make decisions about his RZR Turbo S build. The Turbo S is no bargain-basement ride. It comes with 15-inch wheels, ITP Coyote 32-inch tires, four-point harnesses and an aluminum roof. It even comes with a cool steering wheel, built-in GPS and computerized suspension. The suspension arms, tie-rods and radius rods are all great stuff as well. Cavish’s dilemma was, do you replace perfectly good, new parts with aftermarket units? Cavish decided to seriously refine the machine but not make it a rolling catalog. Only parts and accessories that added comfort, safety or convenience made the cut. This is hardly a budget build, but it is sensible.

A Polaris RZR Turbo S is an ultra-capable machine right off the showroom, but a list of sensible additions made it even better.

STARTING AT HOME

Naturally, Cavish started at work. While finessing the cab area, door-mounted UTV hydration packs added refreshment, padding for the knees and a little storage. Polaris has a nice door frame and latch system, but the doors are not complete. Assault’s Tank aluminum doors mount right to the stock door hardware, and they look great while keeping trail trash out of the cab.

Large-diameter tires, plenty of rubber on the ground and supple, reactive suspension make this car a pleasure on the roughest of trails.

Sidewinder convex side mirrors and a Stealth convex rear-view mirror allow the driver to see the losers back there in the dust. Flanking the center mirror are Assault Ghost tinted sun visors for those annoying times you are driving into the sun. An Assault grab bar is pure billet aluminum art, but it provides a comfortable and secure grab point. Not everything in the cab is from the company store. Polaris seats are quite flexible, and we often wonder if that is purposeful to isolate the passengers from shocks. Whatever the reason, Cavish isn’t a fan, so he opted for Simpson ProSport seats that are amazingly comfortable and supportive. He stayed with the stock four-point belts. A final interior change was Rugged Radios equipment that allows both car-to-car and helmet-to-helmet communications. That may sound like a luxury, but after you have experienced being connected with the group, it is hard to be without it.

We like having side mirrors, as well as a mirror inside the car. You don’t realize how nice they are until you drive with all three.

The rear of the machine was assaulted as well. Assault has a sweet Adventure rack that mounts to the cage and covers the bed. It flips up on gas struts, and Cavish uses it to secure an Assault storage bag. With the rack the bag doesn’t need to be tied down. You can carry more cargo atop the rack or use it to hold a spare tire. Two quick-release UTV fire extinguisher kits are mounted to the cage bars as well. One holds an actual fire extinguisher, but the other holds an uber-handy compressed air tank for filling tires.

Cool grill insert, quality pod lights, sweet mirrors and handy sun visors. Note the A-arm protection as well. There is a lot to like up here.
Walker Evans Racing Walker links allow the sway bar to work without bothering the suspension action. The trailing-arm guards are beefy!

LOOK UNDERNEATH

Polaris equips all RZR models with a comprehensive skid plate, but in this case, Cavish wanted more protection—much more. Factory UTV has what it calls the Ultimate UTV kit. It has a complete UHMW (ultra-high molecular weight) plastic skid plate, front A-arm guards and rear trailing arm guards that wrap the whole arm like a massive taco shell. The kits are available in 3/8-inch material or in full 1/2-inch-thick material. This RZR has the 1/2-inch protection. UHMW plastic is dense, smooth and slippery, so it is ideal protection as a skid plate. It slides across rocks rather than hanging up on them.

Vision and visibility is important for safety, and Cavish opted for quality Baja Designs amber LED driving lights for the A-pillars of the cage in front to aid the stock lights. Just behind the roof is a rear light bar that has five zones: Red at the outer edges, amber inboard of that and white light in the middle. Under the fenders are rock lights. They look cool at night, but more importantly they help with wheel placement while driving in the dark or even in low light.

Cool grill insert, quality pod lights, sweet mirrors and handy sun visors. Note the A-arm protection as well. There is a lot to like up here.

The final changes were the addition of Walker links to tie the rear sway bar to the rear trailing arms and XD Motorsports beadlock wheels from KMC wheels. The Walker links allow the sway bar to be active, but only up to a point. The net result is a more responsive and supple ride to the rear suspension. The XD Grenade Matte Black bead-lock wheels look good with the red inner rings, but the main reason for having them is to let the car keep driving with a flat tire. Cavish chose to leave the stock ITP Coyote tires on the new rims.

Polaris’ basic bed area has been enhanced with a storage bag trapped under the cool Assault adventure rack. The high-mount rear lights aid safety.

THE TEST

We had the pleasure of watching, riding in and driving Cavish’s Assault Industries RZR Turbo S at scenic Moab, Utah. With the Turbo S wide stance, long travel and 32-inch tires on 15-inch rims, this machine is made for Moab. The large tires and beefy suspension allow the car to ease across cracks, crawl up stair-steps and swoosh through sand and loose scree rocks. There aren’t many whoops on the trails, and fewer that you can hit with speed, but the comfort setting on the suspension was more than welcome. This machine is simply a natural. The seats and steering wheel are great, we like the full doors, and it is great to have three mirrors to assist the reverse camera.

Assault’s adventure rack is amazing. It contains any cargo under it, pops up on gas struts and is strong enough to support a spare tire and wheel.

For any driving adventure, having storage is awesome, and the rear rack and the various bags add that option. For any area, but especially Moab, the added under-car protection is a major bonus. This car rides nice, pampers the passengers and has all the performance you could need by virtually any standard.

In this case, stock seat belts are fine, but you gotta love these Simpson Pro Sport seats. They are comfortable and supportive for long rides.

CONCLUSION

The parts used here total up to a good number when added to the already premium price of the Polaris Turbo S with its GPS and computerized suspension, but it makes an almost ideal adventure car. We enjoyed every mile, and we felt reassured by the safety factor of the lighting and radio communications. This car is just right on the accessory scale in our book. ο
