LIFT KIT INSTALLATION TOLL - Part Number 97-53
The .500 - .600 Lift Kits for Big Twin features a special tri-spring (outer / intermediate / inner) interference fit to reduce harmonics and control installation and complete instructions are included. The tool is supplied with 3/8" pilot for stock guides. Additional machining is required to lower the height of the valve guide to avoid interference with the top collar. Springs have more pressure than stock and can be used with .500 lift or .600 lift cams. Combined loads: 180 @ 1.600; 320 @ 1.100; 360 @ 1.000. Coil bind: .930. Recommended cam lift: .500 - .600. Each Manley Spring Kit is attractively skin packaged and clean storage. Kits requiring special machining operations include complete instructions. Every kit is engineered with interference fit, reverse wound springs to reduced harmonics and control spring surge. Manley has introduced "K" series spring kits which include Manley chrome moly heat treated keys correctly matched to the top collars.
