    10° Design Eliminates Retainer Extrusion Problems

    Engineered to work with Manley 10° Retainers, these 10° valve locks are made from the highest quality lightweight titanium material, are thicker than competitor locks. A favorite among drag racing engine builders, Manley 10° Titanium Valve Locks are strong, reliable & durable. Manley supports both conventional and Bead Loc groove systems with an extensive lineup of premium valve locks.

    The groove in a valve stem is imperative to proper valve performance. Inferior grooves, unsuitable retainers, or mismatched locks can cause catastrophic failure. Though conventional (or square) grooves are very popular, their success depends on precise machining. The groove's surface must be impeccable (i.e., no residual machining marks), and the groove requires an exact .013" radius in the upper corner (too large a radius increases the chance of groove abrasion; too small a radius exposes the groove to sharp fillets). Even perfect conventional grooves, however, are subject to the abuse of substandard components. Enter Bead Loc... Intended to be simple and forgiving, the Bead Loc groove has a .110" full radius, and radius contact points are not at the groove's root. This minimizes vertical movement, especially in the presence of a valve float, to lessen valve erosion for longer service life.
