What is a hydraulic roller camshaft and why is it an upgrade?

A hydraulic roller camshaft uses roller bearings to reduce friction between the camshaft lobe and the lifter, compared to traditional flat tappet designs. This results in less wear, more consistent valve lift, and often allows for more aggressive cam profiles that can improve engine performance and efficiency.

What specific components are included in this K-Kit?

This K-Kit is comprehensive, including the camshaft, hydraulic roller lifters, valve springs, retainers, valve locks, valve stem seals, and a timing chain set. It also includes assembly lube and installation instructions to help ensure a proper setup.

Are there any special considerations for installing this camshaft kit?

Yes, this kit is not CARB approved and cannot be shipped to California due to emissions regulations. Always follow the manufacturer's detailed installation instructions carefully, paying close attention to timing and valve train setup for optimal performance and engine health.
