Cost VS Quality

• Compare our product to the competitions product and the cost

Graves Product

• Adjustment shaft is made of aerospace quality steel machined to a 1.0 threads per millimeter allowing the tuner to adjust the tension on the chain to an exact specification = less friction and consistent cam timing = more power.
• The Competitors shaft is made of mild steel all thread material with SAE course thread 

Graves Cam Chain Body

• Designed to support the shaft as close to the cam chain running block as possible for maximum shaft support and minimum shaft flex. The body is machined to allow the exact amount of oil exiting the body to minimize over oiling of the valve train area at high rpm. All of this = more power, accurate cam timing and less friction.
• The Competitors Body Designed to hold the shaft and plugs the oil relief hole 

Graves’s lock nut

• Made of 7075 T651 and hard anodized for a reliable fit, strong threads, light weight and great looks
• The competitor’s nut course thread steel nut

You can compare the price but you cannot compare the quality. Take both of these to your engine builder and ask them which one they would install in your motor when their reputation is on the line!
