Speedmaster PCE269.1001

Speedmaster PCE269.1001 is a set of 7-degree chromoly valve locks for valves using an 11/32 in stem and one conventional lock groove. The machined split locks connect the valve stem to the spring retainer while maintaining standard installed height.

Application / fitment

The locks are semi-universal for stock and performance valvetrains using 7-degree retainers, 11/32 in valve stems and a single conventional groove. All three features must match; do not combine them with 10-degree retainers or multi-groove valves.

• part type: split valve locks / valve keepers
• intake and exhaust valves with nominal 11/32 in stems
• 7-degree valve-spring retainers
• valves using one conventional lock groove
• stock and performance engines of various makes after dimensional confirmation
• component count: 32 lock halves, forming 16 pairs for 16 valves

Inspect the valve groove, retainer angle and full engagement of both lock halves before installation. Use matched locks from the same set and confirm an even pair on every valve. After releasing the spring compressor, verify seating, installed height and clearance from the valve-stem seal.
