7.3 Powerstroke Stage 2 Beehive Valve Springs — Comp Cams COMVS-ST2

Comp Cams Stage 2 beehive valve spring kit for 1994–2003 7.3L Powerstroke engines. Higher seat pressure than stock, Comp 910, or Stage 1 springs to keep the valves seated under bigger injectors, higher boost, and higher cylinder pressure. Kit includes Stage 2 beehive springs, steel retainers, and super valve locks.

Stock and mild 910-style springs were not built for hybrid injectors, 275cc+ fueling, or high-boost 7.3 builds. When cylinder pressure climbs, the valves can lift off the seat, causing lost power, a miss, and valvetrain damage. Comp Cams Stage 2 beehive springs add the seat pressure and control those builds need. The tapered beehive design spreads stress more evenly, cuts valvetrain mass, and helps damp harmonics compared with a conventional cylindrical spring.

Stage 2 Pushrods are required when running Beehive valve springs. Also recommended with ARP head studs on any high-pressure 7.3 build.

A 7.3-specific valve spring compressor tool is strongly recommended. Follow the factory service procedure for rocker removal, spring replacement, and valve adjustment. Check installed height and coil-bind clearance before final assembly. Replace tired stock springs before adding large injectors, high boost, or Stage 2 pushrods.
