Returns:
Camshafts are test-fit only. Once a cam has been fitted, oiled, or the assembly lube disturbed, it is no longer resalable and cannot be returned. Please check the part number against your order before it goes anywhere near the block.
Supporting Components:
The supporting components specified above are required. Running the cam without them will affect performance and may damage the camshaft.
Tuning & Set-Up:
Check the tuning and set-up requirements for your application before ordering. Some engines require professional tuning, Carburettor or ignition timing adjustment. A change in idle quality, vacuum and drivability is a normal characteristic of a camshaft change — not a fault, and not grounds for return.
Break In:
Where break-in instructions are supplied with the camshaft they must be followed exactly. Incorrect break-in is the number one cause of lobe wear and is not covered under warranty. If instructions are not supplied with your camshaft, message us and we will send you a copy.
Warranty:
Warranty covers manufacturing defect only. Damage caused by incorrect installation, insufficient break-in, incorrect springs, wrong lifter preload or valve-to-piston contact is not covered. Warranty assessment requires the camshaft to be returned to the manufacturer for inspection.
Not sure about something? Message us before you order. We'd rather spend five minutes checking than have you pull an engine apart twice.
