This machine was built to take the family on adventure excursions in style. This unit was built by the national sales manager at Trinity Racing and Streamline Brakes, Ryan O’Hara. Along with power products and brake parts that the company provides, this machine was surrounded by a new cockpit up top and equipped with the latest suspension components underneath.

HCR SUSPENSION
HCR (Hard Core Racing) has been in the UTV aftermarket game since the beginning. They were huge in Rhino parts that included door inserts and cargo racks. However, the company really took off when the Polaris RZR came out and HCR built one of the first long-travel kits for it. Back then, even Polaris probably didn’t see the potential for that type of platform. Fastforward 10 years and HCR is a major player in the UTV game, so much so that they are building race vehicle packages for the world-famous King of the Hammers race, fully equipped and with additional prize money available. HCR still makes body panels and skid plates, but their signature component is the suspension system. We have always claimed that their box-tube A-arms looked trick and way beefy, so for this vehicle having super-strong components is a good choice. HCR outfitted it with their OEM replacement suspension arms on all four corners for $3500. Up front, four new boxed A-arms were installed and controlled by Walker Evans shocks. The width and travel remain at stock specs. If you are looking for something not so beefy, HCR sells an Elite set of arms. The Honeycomb arms are made from a secret alloy that HCR claims is 30 percent stronger than chromoly. Reducing unsprung weight makes shocks work a lot less, which resists fading and keeps oil clean longer. As far as weight goes, the arms are only 4–5 pounds heavier than stock up front and 1 pound heavier per trailing arm in the rear. The Elite arms are marketed for the dune guy who wants added travel without a lot of weight. However, these too are strong enough to be driven in the dirt with a UniBall upgrade and a weld-in frame gusset kit, which this machine has for $60. The standard-length Elite A-arms and trailing arms cost $3999. The 4-inch-wider long-travel set sells for $8999 and comes with new King shocks and longer Summers Bros. axles. We have always liked HCR products, and we love the standard and Elite arms. You can call HCR directly for parts for any brand UTV at (888) 928-7223.

In addition to the HCR suspension, this build has a host of useful products from a company called Shock Therapy. Inside the Walker Evan shocks, Shock Therapy did their complete re-valve for $750. Before the re-valve, the rear shocks were upgraded to the 2.5-inch bodies, which that car desperately needs if you plan on carrying passengers. That upgrade runs $1,359 for the pair. Also, at the rear end Shock Therapy dual-rate springs were added with adjustable crossover rings for $1050. To help suspension action in the rear even more, a sway bar kit ($550) was added, along with very important sway bar frame supports ($199). These supports bolt in place using the motor mounting points and the stock sway bar mounting points to tie the whole thing together. Sway bar mounts have been known to separate from the frame, especially if you get away from using the stock sway bar. Up front some strengthening was done in the form of a $245 Racer Tech front A-arm brace and a set of heavy-duty replacement tie-rods for $265.

STREAMLINE/TRINITY
Now that Streamline and Trinity Racing are under one roof, it’s a perfect marriage of added horsepower and better stopping power. You shouldn’t have one without the other. For this RZR, oversized rotors were bolted on all four corners for $543, along with sintered brake pads at $115. A custom steel-braided brakeline kit was also used at both ends for a total price of $180. On the power side of things, a dual-muffler, single-head-pipe, full-exhaust system wasn’t overly loaded and sells for $899. To get the most fuel flow from the intake side, there’s the auto-tune Dynojet Power Commander PC5 tuner ($399). To see it all working, a $249 Power Commander POD-300 LCD display was stuck to the dash. With this product you can see exactly what your fuel system is doing and confirm it is working perfectly as it should. Before the air enters the motor, a UMP Play Car filter kit does its filtering magic at $500. The engine was cooled by a $400 oversized CBR radiator.

COCKPIT COMFORTS
Inside the cabin Ryan wanted the ride to be as comfortable as possible. For communication, he put in a complete intercom system and FM/VHF race radio from PCI ($1199). PCI also supplied the fresh air system ($241) that will keep all dust out of the passengers’ helmets. All four passengers get to sit in plush Beard seats installed using strong UTV Inc. seat bases. Beard harnesses keep the occupants secure. Underbelly protection was provided by a Factory UTV UHMW skid plate. This $679 plate covers key areas underneath that the Polaris plates don’t protect. Polaris does provide a great interactive GPS system that this car has right in the dash. For offroading, this system does all you need by mapping routes, marking points of interest and even offering vehicle diagnostics. To outfit an older car, the price is $950.

FINISHING TOUCHES
For traction, GBC Mongrels mounted on Method 401 beadlocks and connected to the car using ARP wheel studs were a great trio in our eyes. Stronger wheel studs are a must on RZRs when you go to a wide-offset aftermarket wheel, especially a heavier one with beadlocks and, in most cases, carrying a heavier eightply tire. Most automotive shops can cross reference your RZR wheel stud and get you the right ARP studs. The theme of this build was strength and comfort, and both are good qualities for an off-road build. However, if your build is something you’re taking your family out in to enjoy the weekends, it’s mandatory.
