COMP Cams 5761 camshaft phaser limiter kits are specially designed pieces that restrict camshaft phaser sweep. While this technology provides fuel efficiency and the ability to always be in the best position for maximum power, regardless of engine rpm, it does present some limitations when it comes to performance. With such a wide range of valve timing movement, there is very little piston to valve clearance, which limits you to small cam profiles with little overlap.
COMP Cams 5760 adjustable phaser lock kits allow the end user to lock the camshaft phaser. They allow the use of larger, more aggressive aftermarket camshafts. If you're looking for a way to gain more precise centerline control at high rpm under extreme conditions, these high-quality adjustable phaser lock kits by COMP Cams will do the trick.
