Head Porting – CT Racing has done significant amounts of flow bench and dyno testing to offer you the best port layout for your application.

5 Angle Radius Race Valve Job for +1mm 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.

DuraBlueEliminator
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.

durablue_x-33_axle
Dura Blue Eliminator X-33 Pin Drive Axle with BILLET Hubs – This X-33 axle uses the same design, superior material and heat treating as the X-33 w/ cast hubs. The unique difference is in the wheel hub and that they are billet aluminum for superior strength.
