Tony Pellegrino, owner of Genright Off Road, wanted to challenge the King of the Hammers with an impossible mission: to finish the toughest one day off-road race in the world aboard his Jeep JKU Terremoto. Mission accomplished for Tony!

At the King of the Hammers 2019 I had the pleasure and the honor of sitting next to Tony Pellegrino on his Terremoto to participate in the Genright KOH Experience. Already on that occasion I had the opportunity to appreciate its off-road skills and build quality.
Terremoto: a special Wrangler JKU
Terremoto, a Jeep Wrangler JKU, was built by Genright Off Road in 2014 to expose it as a show car at the Sema Show. "We removed every standard element from this Jeep", explains Tony Pellegrino, "and we started to rebuild it starting from the chassis and body using all our products". Over the years, the Terremoto has always been updated and improved and has accompanied Tony in every offroad adventure and show, quickly becoming the Genright Off Road flag.
Tony Pellegrino's challenge: to race the King of the Hammers with a street legal Jeep
On the occasion of the 2020 King the of Hammers, Tony Pellegrino wanted to get involved in a new challenge: “I wanted to demonstrate that the products we sell to our customers resist the most demanding uses possible, and I did just that by finishing with a Jeep JK 4 doors (street legal) the King of the Hammers (in the 4400 Unlimited class) in front of over 60 Ultra4 vehicles built specifically for the race ".
During the 2019 Thanksgiving period, Tony Pellegrino with some friends and customers spent 10 days in the Johnson Valley and on that occasion Nick Repanich, Tony’s friend, accompanied Tony on the Terremoto along all the Hammers. On that occasion they joked about how nice it would have been to participate in KOH with the Terremoto. “After returning home,” Tony says, “I called Nick and asked him if he would be interested in participating in the King of the Hammers with me. I told him think about it ... and before I could hang up he said yes! In mid-December, Nick came to Genright to help me and work to adapt the Terremoto to the KOH rules".
Without taking away resources and time to prepare Jordan Pellegrino's (Tony's son) car, the Terremoto has been updated in the various parts required by the KOH regulation and in the parts most subject to wear. After a 300-mile road test (I remember that the car is steet legal) to verify that everything worked perfectly, the prerun began in Johnson Valley.

"Most of the drivers would not have done it with the race car," says Tony, "we had good feelings for the great challenge that awaited us even if what worried me was the deterioration of the course after the UTV race, the Every Man Challenge and T1 race. Finally, although I am somewhat familiar with the Hammers, I had never driven the Backdoor down in a Jeep. We went to see if it was possible to do it without rolling over; I tried it 4 times to be more confident".
Mission accomplished! Tony Pellegrino ends the King of the Hammers on board the Terremoto
After 11 hours and 45 minutes, Tony Pellegrino crosses the finish line of the King of the Hammers 2020 in 32nd position, completing the mission of showing the whole world that the Terremoto set up with the Genright standard suspension system and all parts of Genright Off Road would have resisted the brutal King of the Hammers and not in the lower classes (4600, 4500 or 4800 of the Every Man Challenge), but in the Unlimited 4400 category with the hardest race course of all: 3 laps, one in the desert and 2 along the trails more demanding, for a total of 212 miles.
