The King of the Hammers 2018—Mitch Guthrie Jr. Wins It With Rhino 2.0 Axles

The UTV portion of King of the Hammers 2018 is over. Right now racers are loading up their broken RZRs, Mavericks, and YXZs and starting the trek home where they will repair, upgrade, and enhance their machines in anticipation of next year ’s race.

But what a race it was! 118 racers entered King of the Hammers 2018 but only 12 finished. Twelve! That’s a far cry from the 30+ finishers in 2016’s race and the 40+ finishers from last year, and that means 106 racers either broke down or couldn’t complete the course in the 8 hours given to them. It’s a real return to form for KOH and a testament to just how brutal the race was. In a race as tough as that, crossing the finish line with all your fingers and toes is victory in itself, and we had 3 of our sponsored racers running Rhino 2.0 axles. Here's the full official list of finishers:

Mitch Guthrie Jr., Mitch Guthrie Sr., and Ross Pilgreen all ran Rhino 2.0 axles and they all did very well as you can see. Pilgreen also ran our 4" portal gear lift. If you want a machine capable of conquering King of the Hammers, start with Rhino 2.0 axles at

The King of the Hammers is the ultimate UTV race—if you’re a UTV enthusiast, you won’t miss it. It’s 134 miles split into 2 laps of open desert, tricky rock shelfs, boulder-filled canyons in southern California’s Johnson Valley. It’s an 8 hour endurance race that tests not only the ability of the driver, but also the durability of their machine.

Racers' results and finishing positions are calculated based on their corrected time (the actual time spent on the course, not necessarily finishing position). KOH is a no-chase race, which means racers have no safety net if they break down away from a pit—they must make the repairs themselves with whatever supplies they brought with them. Make no mistake, the best racers rise to the top every time, but any small breakage or mishap can take any veteran driver out of podium position or leave them stranded in the desert with a DNF.

The Race

The race started at 8AM PST Wednesday morning February 7th with the father-son combo of Johnny and CJ Greaves taking off from the starting line in the 1st and 2nd positionsin their Yamaha YXZs. 30 seconds later, Casey Currie and Sean Stroud left the starting line followed by Mitch Guthrie Jr. and Darian Gomez another 30 seconds after that. It took 30 minutes for all 118 races to start, meaning the last starter had until 4:30 to finish.

Lap 1

The 134 mile course is split into 2 distinct laps: lap 1 is primarily high speed desert racing with some rock obstacles, while lap 2 is mostly difficult rock obstacles with only a few short sections of open desert racing.

Lap 1 is shown in green and raced clockwise. Lap 2 is shown in red and raced counterclockwise. The leaders of the race found their positions immediately with CJ Greaves in front, Johnny Greaves right behind in 2nd, and Mitch Guthrie Jr. battling for 3rd. The Greaves’ YXZs were perfect for the open desert and it was all Guthrie could do to keep up. They made short work of The Notches, The Wall, Resolution, and Backdoor before finishing lap 1 in 1:47 for CJ, 1:49 for Johnny, and 1:54 for Mitch Jr. An exciting first lap to be sure, the real nail biting action was still to come.


For as easy as the race leaders made backdoor look, we saw some other racers struggle with the 6-ft.+ rock shelf.  We had a good view on the livestream of several guys landing on their hoods on the way down including one Travis Zollinger who managed to roll his vehicle onto its side at the top of the shelf. With no room to winch back onto 4 wheels easily, his only course of action was to hit the gas, scoot over the edge on 2 wheels, and say a little prayer. Needless to say he didn’t land on all 4 wheels and the trail crew had to jump in to get him upright. Still, the maneuver probably saved him a few minutes.

That wasn’t the only slick moves we saw at Backdoor. You see, the trick to Backdoor is to throw your vehicle into 4 wheel drive and hit the gas right before your front tires hit the ground. That way your front end pulls forward and keeps you from tipping forward onto your hood. If you’re in a Can Am Maverick X3 with a Visco Lok differential, that can get a little funky as we saw. This X3 came down in 4 wheel drive and slammed on his gas. Unfortunately his front tire had to turn a few times before the diff would lock. What resulted was a quick pirouette on his nose before landing on all four wheels but facing backwards. He popped it into reverse and went on his way. It was rad.

Lap 2

Lap 2 is where all the most intense rock crawling took place and where most riders were forced to quit. It's also where Mitch Guthrie Jr. took the lead—and boy did he take it. The Greaves both cruised through the first few rock gardens easily with Guthrie Jr. in tow. But CJ Greaves found the limits of his YXZ when he was hit by Sledgehammer—a high walled gorge with huge boulders and no good route through.

CJ rolled it and couldn't find an anchor for his winch. He was stuck. His father, Johnny Greaves was right behind, but when you’re that far up in the pack you don’t stop for anybody. But maybe he should have. Johnny made less than stellar time through Sledgehammer. A little father-son cooperation could have been mutually beneficial for the pair. Instead, Mitch Guthrie Jr. crawled right through Sledgehammer leaving them both in the dust. And he didn’t stop. He plowed through Chocolate Thunder, Jackhammer North, and Jackhammer before the course led into 4 miles of open desert. By the time Mitch reached the next rock crawling section, the next racer behind him just made it to Chocolate Thunder. By the time he made it to the next pit, he had a 5 mile lead.

Guthrie finish KOH 2018

It was smooth sailing for Guthrie Jr. after that and he made short work of the 4 remaining rock crawling sections showing his skill as a driver, and let’s not forget the Rhino 2.0s turning his wheels the whole way through.  When he finally made it back to Hammertown to cross the finish line, he had 10 miles between him and the next racer. Nobody navigated the rocks better than Mitch Guthrie Jr. on Wednesday and he came away with a definitive win—his first and the seventh for the Guthrie clan.

Guthrie Jr. Atop the Podium

Mitch Guthrie Jr. took the checkered flag in 6 hours with miles between him and the next finisher, CJ Greaves. Final corrected time results put Mitch Guthrie Jr. on top with a time of 5:54:43. Branden Sims came in 2nd with a time of 6:36:58. Mitch Guthrie Sr. came in 3rd with a time of 6:53:07. That’s 42 minutes between 1st and 2nd place—Guthrie Jr. was first by a long shot. During post race interview, Mitch Guthrie Jr. said that nothing broke and he only had to winch once. Clearly a good machine and some great driving. No wonder he destroyed the competition.

Guthrie Sr. Started in 28th position, but his experience from 6 previous King of the Hammers wins was all he needed to push through all the traffic and land that 3rd position. He said they took the course carefully this year, and it was his slowest race finish so far. He was also visibly choked up during post race interview when talking about how well his son did. We’re expecting to see a lot from Jr. in the years to come.

The two Guthries along with Ross Pilgreen make 2 top 10 finishers all running Rhino 2.0 axles. Pilgreen also ran our GDP Gen 2, 4″ Portal Gear Lift, so to those of you worried about that 30% gear reduction slowing you down—don’t. Pilgreen screamed through the open desert without overheating his portals (thanks to precision ground gears) or blowing a box. When he made it to the rock gardens on lap 2, his gear reduction and extra clearance gave him a massive leg up on the competition. He cruised through those boulders where other guys had to winch every 30 yards.

Overcoming Starting Positions

It’s really impressive that Pilgreen, who started 29th, and Guthrie Sr., who started 28th both came out with the finishes they did. Even though their positions were calculated on corrected time like rallycross, starting position makes a bigger difference at King of the Hammers than most other races. That’s because racers often have to line up to get through obstacles like Backdoor—a single, narrow, 6 foot tall shelf that every driver is required to descend. When one driver bungles the landing and ends up on their hood, the rest of the racers waiting in line have to wait even longer. But if you’re out in front or near the front, there’s less waiting, and less chance of major blockage in those tough sections.

Pilgreen and Guthrie Sr. had to battle through droves of vehicles clogging up obstacles to land their finishing positions. You just can’t do that without some serious driving skills.
