Frequently Asked Questions
What is a DLC-coated camshaft?
DLC (diamond-like carbon) is a very hard, low-friction coating applied to the cam lobes. It resists wear and scuffing, which helps on high-load and performance builds.
Should I replace the followers with a new cam?
Yes. Running new lobes against worn followers or rollers shortens cam life. Ask us and we will quote the matching parts.
