Fasstek Racing Long Stroke Crankshaft Kits are great solutions to increase the performance and torque your machines. These kits will increase your engine’s displacement (cc) for great performance gains. The crank webs are reshaped and optimised for the best engine balance and vibration reduction. These kits come assembled and balanced with enhanced and strengthened con-rod kits.

Longer conrod for modified rod ratio and lower vibration. Requires extra thick block spacer. For advanced builds only. 

• Increases total stroke by 16mm (8mm up+down) 
• Connecting Rod length - 111mm 
• Block bottom spacer required - 19mm 
• Includes: Crank bearings. Crankshaft sprocket 

Note: For R15v3/V4/MT and similar VVA models, you need to add a 1mm bottom spacer/increase spacer thickness +1mm as the standard rod is 1mm shorter(99vs100mm). You will also need to reuse the stock bottom crank timing gear.
