CT LTZ/KFX400 Pipe Kit

Our CT pipe kit consists of the complete exhaust system including a 7 disc spark arrestor and jet kit. 7 discs produce the maximum horsepower on a stock LTZ/KFX400 with the lid off the air box. Removing the discs and going to an open end cap or adding more discs to a stock motor will lose peak horsepower. This system produces a very quite 95dBs. The air box lid can be run, but it will result in a loss of horsepower. The CT pipe is completely tunable. As you add horsepower to the motor with performance parts, you can add discs to achieve maximum horsepower.

 

The dyno chart above shows the stock LTZ/KFX400 horsepower in red. Our CT pipe with jet kit is shown in blue.

LB-020 LTZ/KFX400 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.

LB-023BV LTZ/KFX400 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. Seats not included.

Axles

AX-DB-20-1137 '03-'08 LTZ/KFX400 Dura Blue Heavy Duty Axle 

This axle is a recreational level axle that is twice the strength of the stock axle. It's a cost effective choice when reliability is a prime concern.

$356.40
AX-DB-20-1137SP '03-'08 LTZ/KFX400 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).

$468.90

AX-DB-20-1137EX '03-'08 LTZ/KFX400 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.

$612.00

AX-DB-20-1157 '09 LTZ400 Dura Blue Heavy Duty Axle 

This axle is a recreational level axle that is twice the strength of the stock axle. It's a cost effective choice when reliability is a prime concern.
