Dual Conical Valve Spring Set, 485lb/in Spring Rate1.060"/1.390" OD, .660"/.990" I.D, 160lbs @ 1.900" Seat Pressure, 1.165" Coil BindBrand: COMPPart Number: CO7256-16Description: As opposed to dual cylindrical spring systems, COMP Cams® Dual Conical ValveSprings require no interference fit to dampen spring surge. The self dampingcharacteristic of conical geometry, along with the lowerspring kinetic energy of the upper coils, provide a game-changing breakthrough in valve spring design. COMP Cams® Dual Conical Valve Springs are constrained at thetop and bottom with stepped retainers and spring seats to create separation. The result is that the springs’ naturally progressive nature can provide outstanding damping without rubbing friction or the associated heat and surface damage. Thesesprings are designed for circle track, road race and drag racing applications, as well as all-out, high-RPM street/strip hydraulic roller valve train systems with optimized lifters.
- Dampen coil oscillations, increase RPM limit & reduce resonance
- Improves valve train stability
- Fewer parasitic horsepower losses & more power
- Superfinishsurface processing
- Non-interference fit
