Overview
This complete steel hold down kit is for a shaft-mounted rocker arm system on the Mopar small block LA 273–360. Heavy-duty machined steel hold downs (stands) replace cast or worn supports and won't flex or crush under high spring pressure. That keeps the rocker shafts rigid and the valve geometry consistent. The kit includes the 5/16" studs and fasteners plus a spacer and shim kit to set rocker alignment, so you have everything needed to mount a pair of rocker shafts.
It suits performance builds running aluminium or stainless shaft rocker arms. Rocker shafts and rocker arms are not included. Check your cylinder heads, shaft diameter and hold down bolt size (5/16") against your existing setup before ordering.
