1.550in Valve Springs - BBM

The Edelbrock 1.550in Valve Springs BBM (part number 5792) is a direct replacement valve spring set engineered for Mopar B and RB-series engines. This complete set of 16 springs delivers the precise seat pressure and lift characteristics required for dependable valve train operation across stock and moderately modified engine builds. The 1.550-inch outer diameter combined with a 1.160-inch coil bind specification ensures proper clearance and seating geometry in factory cylinder head configurations.

Edelbrock valve springs are manufactured to exacting tolerances and include both the main spring and damper in each assembly, eliminating guesswork during installation. The dual-spring design with integrated damper controls harmonics and prevents surge across the RPM band, critical for valvetrain stability in high-mileage engines or those subjected to increased operating temperatures. Spring rate and bind specifications are matched to factory cam profiles, making these springs suitable for stock restoration or as part of a basic performance refresh without requiring additional cylinder head modifications.

This spring set is ideal for Mopar B-block (318, 340, 360 cubic inch) and RB-block (383, 400, 440 cubic inch) engine owners performing valve train service, head gasket replacement, or preventive maintenance. Whether you're rebuilding a classic muscle car, restoring an original Dodge or Plymouth, or refreshing a long-storage engine before recommissioning, having a matched set of quality OEM-style valve springs ensures consistent valve timing and eliminates the risk of weak or fatigued springs causing misfires or loss of compression.
