LB-020 LT-R450 Head Porting

CT Racing has done significant amounts of flow bench and dyno testing to offer you the best port layout for your application. We highly recommend getting a valve job at the same time the head is being ported. Our CNC valve job ties in with the port work to offer extremely effective flow numbers.

Quality valve job.

$144.00
LB-023 LT-R450 5 Angle Radius Race Valve Job

LB-023BV LT-R450 5 Angle Radius Race Valve Job for +1mm Intake & Exhaust Valves

The 5 angle radius Race valve job significantly raises the flow characteristics at low valve lift and definitely shows a horsepower increase throughout the useable power curve. The 5 angle valve job really shines on big valves as the seat diameter is opened up all the way into the aluminum casting, blending to the port work. Adding +1mm valves to a modified engine package helps the mid to top-end horsepower. Most aftermarket hi compression pistons are clearanced for +1mm valves.

Axles

AX-DB-20-1126SP Dura Blue Eliminator 2+2 Extended Axle

The Eliminator axle used for all forms of racing and high performance applications. Many of the models come with the patented Posi•Lock system which removes threaded sections from the flexing area of the shaft (a source of crack generation).

$400.50

AX-DB-20-1126EX Dura Blue Eliminator X-33 Pin Drive Axle with Cast Hubs

The X-33 axle uses the same superior material and heat treating as the Eliminator. The unique difference is in the design of the wheel hub mounting area. Standard design ATV axles neck down to about 1" in diameter. A splined wheel hub slides onto the axle shaft and is retained with a hex nut. As all ATVer's know, hubs loosen frequently. The X-33 changes all that. The wheel hub is clamped solid and driven by a pin on a 1-3/8" diameter shaft. This axle is rifled to reduce weight near the rotational axis of the ATV. The X-33 allows for 16 different wheel offset alternatives.
