Made in the USA Since 2006

Jordan Pellegrino #98 Ultra4

This is a cutting edge Unlimited Class Ultra4 car designed by Triton Engineering, then built & assembled by GenRight Off Road.

It is a fully independent suspension race car (front & rear) with a 74 Weld portal box at each wheel that give this car 4.5" more ground clearance than a standard IFS car!

It is basically a 800HP Razor, but 1000lbs lighter than the average 4400 Class KOH race car.

Combine that with the new Mickey Thompson Baja BOSS 40" tires and Fox Shox and the car is unbelievably fast across the brutal Johnson Valley Terrain!
