UTV PROJECT: First turbo in the family 

By the staff of Dirt Wheels

With HCR’s Dual Sport kit allowing the use of the stock shocks, the car was a little low in the rear, but it still exhibited accurate handling. We were never chasing the front end in turns.


Sector Seven is the relatively new but innovative UTV product division of longtime off-road parts manufacturer Pro Moto Billet. Company owner Lynn Hodges is in Idaho where there are all sorts of off-road opportunities, so it was inevitable that his family would end up with a Polaris XP 1000 4 in its stable.

As son Sheldon got a little older, he was looking for something sportier to drive, and the then-new Polaris RS1 was added to the family’s fleet. The RS1 project turned out to look amazing, but Sheldon is single and going to college right in the Idaho Dunes area of St. Anthony, Idaho. A turbo and another seat were the obvious next upgrades. Sector Seven also needed a new RZR Pro XP to use for developing and displaying products.

Obviously, the RZR Pro needed to perform well in the desert, mountains, and dunes, but equally important, it had to be worthy of representing Sector Seven at events and shows. It had to draw customers to the Sector Seven display. To that end, there are full half doors and a complete and hopefully even more eye-catching wrap still in the works.


Polaris’s new RZR Pro is a fantastic machine, but it is not unique enough to draw attention on its own. It is also a 64-inch car, and modern thinking is that wider with longer travel is better. Fortunately, Polaris worked with popular industry companies to make sure that the RZR Pro would be a solid starting point for those who leave nothing stock.

HCR had a new dual-sport suspension kit ready. Sector Seven chose the dual-sport kit rather than the OEM replacement kit or the long-travel suspension system. The long-travel kit comes complete with King Off-Road Racing Shocks. The Pro XP Dual-Sport kit provides an 8-inch wider stance for stability. The front A-arms add 1.25 inches of clearance under the lower A-arm arch area, and the arched trailing arms add 3 inches of ground clearance. With this kit, Sector was able to use the stock computerized Fox Live Valve shocks that come with the RZR Dynamix package.

To further ease installation and maintenance, the kit uses OEM caster and camber angles to eliminate the need for adjustable Heim ends, providing a stronger mount for the arm’s pivot points. The OEM ball joints are reused, which maximizes low-speed steering, allows smooth travel, and makes maintenance easier.

The kit is compatible with factory wheels, though new axles are required. The axle requirement isn’t a huge problem, since the kit includes RCV Performance extended axle bars and required hardware. You still need to swap out the CVs, and we can tell you that is something you want a shop to handle unless you have experience with CVs. The usable travel jumps to 21 inches. This is a 100-percent bolt-on installation using factory mounting points. The look of the kit in the red with polished edges and logos is amazing.

Polaris’ 2020 RZR Pro XP Turbo Dynamix is an amazing machine stock, but when you widen the stance 10 inches and boost the suspension travel, you have something special.



Surprisingly, Vent Racing was ready with a complete cage and roof for the RZR Pro as well. The cage includes an LED light bar with welded-on mounts. In addition to being lower and having a more streamlined profile, the cage is strong and includes a full front-to-rear tube under the middle of the roof. Sector didn’t get tabs for the Whip-It lighted whips. It’s a good thing that Sector Seven makes sweet billet clamps to attach the whips and a fire extinguisher. We like the tube grab handles built into the front corners and the color-matched to the body panels and HCR suspension parts.

With just the simple Sector Seven graphics on the stock body panels, cage, and suspension, this RZR Pro would already look pretty good, but the Metal FX Offroad Assassin wheels with SandSports SxS paddle tires really put this build over the top. A U.S.-made 15×8 wheels are built up with a billet center mated to light and strong spun rim portions.

The wheels are first powder-coated a rich, translucent red, then contrast cut to let the aluminum peek through in spots. These wheels are not easy or cheap to build, and the retail price of $750 per wheel reflects that. There is no disputing that these are rolling works of art.

There are more exotic billet parts than just the wheels. All of Pro Moto Billet/Sector Seven’s parts are nice, but the sway bar end links are as exceptional as the wheels. There is no price for the links yet, but the rears, in particular, are stunning. The whip and fire extinguisher mounts are nice as well.

The Sector Seven Spectrum lighted mirrors are whittled from blocks of aluminum, anodized, and fitted with LED lights and curved mirror glass. The magic is that the lights in the mirror illuminate to the front and the side so you literally see around corners. We like the mirror part as much as any mirror that we have used. With everything looking so sweet with the suspension and rolling stock, it is a good idea to protect all that metal art.

Although Rokblokz calls its product a mud flap, the ones on the RZR Pro XP are unobtrusive but nicely protective of the trailing arm finish.

HCR’s Dual Sport suspension kit uses stock mounting locations, shocks, ball joints and more, plus they look sweet. Unlike past long-travel kits, this one doesn’t take a parking lot to make a U-turn.



For some of our crew, it was their first time in the RZR Pro XP as well as on the Fullerton Sand Sports SandSports SxS paddle tires. The fronts are designed specifically for 4WD machines like UTVs. Some sand purists run 2WD in the dunes, but we have done comparisons, and the small paddles, like the SandSports fronts, significantly add to the acceleration and response.

With the added power from the Pro XP’s turbo engine for 2020 and the prodigious traction you get from the SandSports SxS tires, the Sector Seven RZR lets you throw and carve sand like crazy. A wind event the day before our test left the Glamis dunes in prime condition, but parts were soft, dry, and deep. It didn’t matter. Even in soft, deep dunes, the car jumps up on top and slams you back in the seat.

Sector Seven is planning to use the same wheels with trail tires of the same size on all corners, so the wheels are only 8 inches wide. Otherwise, they could have had even more paddle on the sand for better flotation. We were perfectly happy with the 30-inch tires. Too much paddle can drag the power down, and that was not the case here.

Custom radius rods and longer RCV axle bars are included in the suspension kit. From our understanding of the 2020 Polaris Pro XP belt and CVT system, we’d put the cover back on.



We were lucky enough to have a new RZR Pro XP Dynamix demo car along as a performance yardstick. We will be the first to admit that the standard car was impressive. Ten inches of added track width from the HCR suspension, the Metal FX wheels, and the increased wheel travel made a huge difference. Naturally, the Fullerton Sand Sports tires only amplified the difference. There was truly no comparison.

You get so much confidence with the wider machine. You can relax in situations that would make you nervous in a narrower car. Jumps, hits, and transitions are all more effortless. HCR’s kit also raises the front of the car, which makes it harder to see the terrain ahead. The Pro XP is already harder to see in than an RZR S, and the Sector car makes it even a bit harder. Lynn Hodges says he typically sits on a 3-inch cushion for a better view.

These metal-art sway bar links are still being developed by Sector Seven. They look very cool, and we had no trouble with them. The price has not been announced yet.



All too often, brand-new machines that are rushed as builds are compromised in one way or another. Some gain too much weight. Others are geared too much toward a certain use, and some aren’t as flexible as they had been stock.

This is a great build. It looks stunning, performs at a very high level, and doesn’t have excess gingerbread piled on. After belt problems with the old XP 1000 4, Sector removed the RZR Pro XP belt cover for the dunes. From all we know of the RZR Pro, the belt should be fine with the cover on. Aside from that, there is little to find fault with on this machine.

Pardon the pun, but this car shines at night. Sector Seven’s pivotal product is its amazing lighted billet mirrors that let you look around turns. To those, they added an LED bar and Whip It lighted whips.
