Rayce Muchmore of K&T Performance claims he built this beautiful RZR XP4 for his wife.  If that is true I can’t believe she let Rayce come toDuneFest 2014 with it!

Rayce wanted to build a custom four-seater to haul around the family, but seeing as he is part of the K&T Performance family, we knew this would just be a family cruiser. They went all out with a full K&T Performance build, from their bolt-on XP1000 turbo kit, to head porting, turbo pistons, rods and valves. The fuel and timing are handled by a stand alone Motec Engine Management System with a full color display mounted on the dash. The turbocharger is feeds compressed air through an air-to-air intercooler that sits behind the rear seats.

Transferring the power from the engine to the massive paddles is a set of STM Z1 billet CVT clutches. STM Powersports is based in Michigan, and produces high-performance clutches for snowmobiles and UTVs. Their billet clutches adapt the RZR transmission to a larger belt, which allows greater grip and durability when running extreme horsepower numbers. The fully-adjustable clutches are pricey, but worth every penny if you’re running big horsepower numbers.

Out back, the turbo exhaust runs through a set of Sparks Racing pipes that give it just the right about of back pressure and top it off with a nice exhaust note.

With power handled, Rayce turned to suspension. With the extra power, he was looking for a wider stance and more wheel travel.  He turned to Lonestar Racing and installed their MTS +3.5″ arms and high clearance trailing arms.  The chromoly arms widen the stance by 7-inches and also bumps the wheel travel to 20-inches! The factory Walker Evans Racing shocks were revalved and resprung by UTV Resource who also supplied a new sway bar.

Rayce turned to TMW Off-Road for the roll cage and doors on this build. The standard Phantom X-4 cage is lower than stock, but Rayce had TMW drop the rear even more for an aggressive styling, and with kids in the back seats there isn’t a worry about clearance. The sides were finished off with TMW Side Winder doors and up front is a full windshield.

Fullerton Sand Sports supplied a set of Sand Tires Unlimited paddles to put the massive power to the ground.  The rears got a comp cut to lighten them up and give the paddles more bite.  They are mounted on DWT aluminum wheels.

Inside the cab, four Triple X Venom suspension seats were installed with PRP harnesses to make sure everyone stays snug in their seats.

To finish off this awesome car, Rayce enlisted Elite Customs for a complete custom paint job. From a distance it looks sharp, but up close there is a lot of detail that makes this car pop.

We met up with Rayce in Winchester Bay during DuneFest and then again at Little Sahara and snapped a few shots of the car ripping up the dunes.  The car has awesome power and looks great too.
