works adjustable cam pulley









Each Gear is adjustable in 1° increments to a maximum +/- 10°. Our engraved timing marks are accurate within 1 minute of degree! With the simpler design our gears end up being light than the stock gears they replace. Our tooth profile matches the OEM spec exactly for each gear we make. The outer cog section of our gears is black hard-anodized, to prevent on/wear from the timing belt. We use black hard coat because of the great contrast it gives against our engraved timing marks. The 5-bolt locking pattern is plenty secure and we use only stainless steel hardware to ensure durability. This design provides a lifetime of worry-free adjustment. Machining for optimum component fit is critical with adjustable cam gears. Any free play between the inner and the outer sections will cause the hardware to come loose no matter how much is tightened. Our extra care in the machining process guarantees you our gears will not come loose when you follow the torque specifications in our instructions. Horsepower gains can vary widely depending on what has been done to the vehicle and how it is used. Gains from 5 to 20 horsepower can be realized.
