Polaris engines have a lot of potential. With 92 cubic inches, 4 valve heads and a 9.2 Compression ratio, more performance is only a pair of camshafts away. The 438 makes a great setup with a street bike with stock engine or a tuned engine with stock or larger displacement. The 460 cams are a perfect match for the factory 100 kits.V-438 GRIND CAMS- More valve lift and duration means extra power through the RPM (2000-6000+) range for bolt-in or modified engines
- Piston-valve clearance should be checked; uses stock valve springs
V-460 GRIND CAMS- Higher lift cams for modified Freedom motors with big cylinders and higher compression ratio
- More torque and HP with factory 100 kits; RPM range (2200-6500+)
- Uses high-lift valve springs
NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance when installing cams.
