Dustin Nelson raced his YXZ at the Glen Helen WORCS National and got third SxS Pro Stock the first
time racing it. IMG Motorsports built this race-legal cage with V-bar and additional rear tubes, plus a con-
toured aluminum roof with Dzus fasteners. IMG’s two-seat RZR JH2 cage is $2799; call (951) 471-1615.
Dustin also removed the OEM radiator and installed a CBR oversized radiator behind the cab. The UTV
Race-Class kit uses a 22.5x14.5x2.25-inch aluminum radiator with 12-inch Spall fan and sells for $750.
CBR is at (951) 245-2900.
Weller Racing’s full three-into-two dual-exhaust
system from DMC is $1100, and it makes more
horsepower and is much lighter than the stock
system. Going to smaller dual mufflers moves them
away from the shocks, and the OEM muffler is so
close it heats up the shocks and causes fade.
Dasa Racing is also developing a YXZ turbo kit with CBR inter-cooler radiator.
Dasa is at (951) 681-1131, and the Dasa Racing Fuel Controller needed for
its three-into-one exhaust is $229.95.
Familiar with the Viper snowmobile, Mountain Performance already has a
155-horsepower YXZ turbo kit ( 5 psi) currently undergoing EPA compliance
certification. It uses a Mitsubishi turbocharger and is in its seventh generation
of development with a bolt-on inter-cooler via O-ring billet mounts and ducts
into the OEM primary airbox. Stage 1 upgrades jump to 190 horsepower, and
the basic Turbo kit is $3995. MPI is in Utah at (888) 649-4609 and www.
Those who’ve never driven a manual clutch will appreciate Yamaha partnering
with Rekluse to offer the Rekluse EXP clutch for $799.99. The EXP has an
expanding clutch plate that lets the clutch slip at idle, then widen as revs build
to lock up the plates. Rock crawlers will definitely want this Yamaha accessory.
