2016 Polaris RZR 1000 XP4: The Conclusion

Posted in Features on October 17, 2017

Roger Stockton is a guy who when life gives him lemons, he makes lemonade. Take his ’16 Polaris RZR 1000 XP4, for example. He bought the Pro Armor Package unit for his family to have fun with, and fun they had. But during one particular day, he nosed the big RZR in and some damage was done. Mostly to his pride, but enough that the RZR needed some help.

It was while hanging upside down in his harness that Stockton had a revelation — rather than just fix it he wanted it to be better. Way better. So Stockton took it to RothFab Engineering in Riverside, California, where it would be transformed into the car seen here.

RothFab began by cutting away most of the stock frame, leaving virtually only the centersection. They then built a custom tube chassis, incorporating an HCR Racing long-travel suspension system along with a host of mods that make this four-seater a serious threat to any terrain.

HCR Racing of Cedar City, Utah, offers a Dual Sport Long Travel kit that includes boxed front arms, some trick trailing arms with links, sway bar mounts, RCV axles, a Sandcraft Motorsports GEN 2 carrier bearing, and King coilover shocks that have been tuned by Mr. Brett King himself.

The HCR Racing Dual Sport Long Travel kit and King shocks give this RZR the abilty to take on any terrain.
Mounted by RothFab, the rear suspension is again made up of King shocks and HCR Racing components.

A set of STI Chicane RX A/T (32x10xR15) tires have been mounted up to 15-inch OMF Beadlock wheels. They’re held on tight with ½-inch ARP wheel studs.

The combination of 32-inch STI Chicane tires and 15-inch OMF beadlock wheels would have been big enough for a pickup truck not too long ago.

Other chassis upgrades included a custom Harmon Racing 20-gallon fuel cell install, seat mounts, spare tire holder, an intergraded toolbox, and even a custom ice chest rack —because, ice chest. There is a one-off custom upper cage with intergraded air intake for the S&B Particle Separator, a recessed 36-inch RLB Rear Chase lightbar and sound bar.

All of the stock bodywork has been removed and a GlazzKraft Vortex Gen 2/4 body (and their carbon-fiber dash, but we’ll get to that) dropped onto the RZR. It features custom doors but the rear set articulate up like Lambo doors! Very cool. An Assault Industries front bumper is used and onto it are a host of Rigid Radiance light pods. A set of blue accented Heretic Studio billet headlights and a HS 30-inch Wraith billet LED bar provide good forward vision while a pair of 5150 LED whips makes sure the RZR itself is seen. The nice flat black paint scheme was applied by an old friend, one Jeff Styles, who must have been going crazy, since there’s not one pinstripe of his to be found on the RZR anywhere.

More Rigid light pods are mounted near the A-pillar and a 30-inch HS Wraith billet LED lightbar runs across the top of the front opening.

The interior has seen the same amount of attention with some very trick pieces added to the new cage. Custom sliders were produced for the quartet of PRP GTSE 1000 seats. These were equipped with PRP 3-inch five-point harnesses up front and 2-inchers for the rear seats. PRP also supplied the XP1000 door bags.

An Assault Ballistic D steering wheel combines nicely with the Extreme Products gated Speed Shifter to allow for perfect control over the RZR, while the Racepak IQ3 dash, GPS screen and two banks of sPod’s Contura switch panels sit nicely into the very cool GlazzKraft XP1K carbon-fiber dash. There’s also a Wet Sounds Stealth Ultra 10 sound system, and we haven’t even yet mentioned the hidden Gun Vault SZ500 SpeedVault gun safe …

The engine has been enhanced too; Stockton says that adding the Aftermarket Assassins PVCX Level 2 Tuner, HMF Industries exhaust system, and Airaid air filter combined for a 30hp gain. Killer numbers, but, of course, they necessitated an Aftermarket Assassins SP Clutch kit along with a custom RothFab belt-cooler system to keep the system running cool and strong.

Roger Stockton says he’s spent his whole life looking forward to desert trips, first on mini-bikes as a kid, then racing D37 desert and now taking his family out in this amazingly capable RZR. “Fortunately for me, my wife also fell in love with the desert experience, and we passed that on to our two daughters.”

And that’s the beauty of this UTV. It’s giving another generation the chance to experience the outdoors, just as Stockton did when he was a kid.

Intergraded into the top is the air intake for the S&B Particle Separator and a recessed 36-inch RLB Rear Chase lightbar.
With plenty of suspension comes the need for more power, so an Aftermarket Assassins PVCX Level 2 Tuner, Airaid air filter, and HMF Industries exhaust system combined for a 30hp gain.
A set of blue accented Heretic Studio billet headlights gives the RZR a little style and a lot of light.
