— Testing a great UTV build —

Passion is universal, whether it’s OHV recreation, flying, music or home-brewing beer. Ben Cook loved flying and bench-racing about flying afterwards with friends in Hangar 24 so much that he turned a home-brewing operation into Hangar 24 Craft Brewery, complete with the Barrel Roll Program of spirits-barrel-aged beers. Cook also enjoys off-road recreation, so he had Assault Industries create the Hangar 24 RZR XP 4 1000, and we got a chance to sample the tricked-out Polaris in the San Bernardino National Forest and afterwards Hangar 24’s Betty IPA.

Assault Industries built this adventure RZR XP 4 1000 for Hangar 24 president and master brewer Ben Cook, who was nice enough to let us take it for a spin in the San Bernardino National Forest above Silverwood Lake.
Assault arms the Polaris RZR XP for serious rocks and obstacles with trailing-arm guards, shock-shaft protectors and heavy-duty torsion-bar links.


Assault took delivery of the 2017 RZR XP 4 1000 with Walker Evans needle shocks to transform it into a rolling billboard for the Hangar 24 booths at the Sand Sports Super Show, as Hangar 24 was a presenting sponsor. Assault started with a Pro Armor XP 4 Baja cage ($1,949.95) with a roof and pocket for the Baja Designs 30-inch Driving LED light bar ($849). Baja Designs also supplied the rear taillight 30-inch light bar ($424.95) with red, orange and white backup lights and two LED dome lights and switches. An XTS Power Products RZR light-bar wiring harness ($79.95) made for a clean install. Also, a pair of BD Squadron-R Sport driving/combo amber lights ($239.95) were mounted to the Assault Apache front bumper ($249.99), and night rides were further enhanced with the BD RZR XP1K headlight kit ($1,084.95).

The Hellfire V2 front grill has a new rally-striped design and is available in white, yellow, blue, red, orange and lime green powdercoat. Assault also has a Ride Command camera mount for its grills for $34.99.
The Ballistic D steering wheel kit provides extra knee- and legroom and is contoured for comfort. The genuine leather wheel is available with stitching color choices, and the quick-release system locks with ball bearings and is a theft-deterrent.

With the cage and lights complete, armor and comfort were next for the adventure XP 4. Four Pro Armor G2 seats ($429.95 each) were installed with Hangar 24 colors. Assault’s 3-inch H-style five-point harnesses ($139.99 each) went on each seat, and the RZR steering wheel was replaced by Assault’s Ballistic steering-wheel kit ($319.99) with quick-connect. Assault’s Hellfire shifter ($59.99), center-view mirror ($84.99), sun visors ($169.99), storage bag ($155.99) and B2-Bomber side mirrors ($329.99) accessorize the cabin for exploration and strafing runs.

The Adventure Rack fits OEM and some aftermarket cages and is constructed of high-grade 1018 steel with a black semi-gloss powdercoat finish. It’ll hold up to a 32-inch tire with the ratchet Y-strap and frees up the bed for the Assault soft cooler or a #1170 eight-gallon Rubbermaid ActionPacker lockable storage box.


Fuel Racing supplied the 30x10R14 Gripper tires ($175 each) and Anza beadlock wheels ($175 each), with a fifth wheel going on the Assault Adventure rack ($429.99) above the Assault soft cooler ($44.99) and paired with the Apache rear bumper ($259.99). To make sure no rides get cut short, the Hangar 24 XP 4 was armed to the teeth with Assault Turret tie-rods ($309.99) and high-clearance radius rods ($649.99) with a radius rod reinforcement plate ($124.99). Assault’s trailing arm guards ($229.99), front shock guards ($124.99), rear shock guards ($144.99) and sway-bar links ($129.99) protect the suspension, while two fire-extinguisher-mount kits ($169.99 each, including extinguishers) add insurance.

Pro Armor G2 Suspension seats are nicely shaped for comfort and support, and military-spec parachute cords provide suspension. Marine-grade vinyl provides long life, and the loose cushion has a sand drain. G2s are also available in XL and Mud, which has an extra port for drainage.

For style, the Assault Hellfire grill ($124.99), dash bezel ($59.99) and gas cap ($89.99) blend in nicely with the Hangar 24 wrap and logos. With that, the Assault Hangar 24 RZR XP 4 was ready for our adventure above Lake Silverwood for photography. It was a great ride in an awesome machine.
