All camshafts will offer their maximum performance when used with a professionally ported cylinder head and professionally cut valve seats.

IMPORTANT NOTE When installing a high performance camshaft it is the responsibility of the engine assembler to check and confirm that the piston to valve clearance is adequate. Minimum clearance is .060" from valve to piston at peak lift. Tolerances can and will vary from engine to engine. There is not substitute for checking that these tolerances are correct. This is especially critical when mixing camshaft and pistons from different engine builders. One of the correct and easiest ways of checking this is by using the "claying the piston dome" method.
Call DRI or consult a professional technician.

What is the difference between a billet and hardfaced cam?
Billet cams are sold outright with no core required. They are machined in the USA and are specially heat-treated for wear resistance. Billet cams are used when problems arise in the hardfacing process of stock cams.

Hardfaced cams are made from stock cams. In the hard facing process, stock cam lobes are welded with a hard surfacing alloy to increase durability as well as provide additional stock for high-lift profiles. The stock cam (or stock core) can then be ground to almost any desired lobe shape. Some models such as LT-R450 prohibit this type of modification because cam journals can distort in the welding process.

All DRI Camshafts are made in the USA to ensure the best quality. Camshafts are available in different power curve options to fit your riding and racing needs.
