FRP Hemi Phaser Limiter/Lock Out w/ Tool gauge What is the difference betweenHemi 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.
