Norris Aluminum Cam Gear, Made in USA, Helical
For aftermarket camshafts that require a bolt-on gear, this USA made gear is a great match. The helical design is quieter than straight cut steel gears, but is super strong and will hold up to high-rev single or dual springs. TECH TIP: Aftermarket camshafts are all ground to use this "flat cam gear" design, so an early "Flat cam" oil pump will be required when using and aftermarket racing style camshaft. Cam bolts are required. Norris cams come with bolts already. Most other manufacturers require purchasing the bolts seperately.
