VALVE SPRINGS,1.290"HIGH PERFORMANCE GM LT, SINGLE (26919-1)

The Street Performance RPM Series Beehive Valve Spring is engineered specifically for GM Gen IV LS7 and Gen V LT engines. Designed with cutting-edge technology and advanced materials, this 1.900-inch installed height spring delivers unparalleled durability, stability, and performance for today's street-driven high-performance builds. Constructed using COMP's signature super-clean wire, each valve spring undergoes precision heat treatment to ensure accurate spring rates and improved strength. To further maximize service life, the springs receive a multi-peen process, polishing, and COMP's Ultra-Peen surface treatment, resulting in exceptional fatigue resistance and long-lasting reliability under extreme conditions. The unique beehive profile of the spring provides a drop-in fit for LS7 and LT applications, reducing both spring and retainer weight for improved efficiency. Combined with the ovate wire design, which positions the maximum area of the wire at points of highest stress, the spring handles load more effectively while dissipating heat for longer service life. This design not only enhances efficiency but also supports a maximum valve lift of 0.650 inches within its optimized geometry. This spring delivers outstanding stability at high RPM. The innovative shape and construction increase harmonic resistance, eliminating damaging vibrations and harmonics that rob power and shorten component life. The result is increased torque and horsepower at higher engine speeds, while also enhancing overall durability for demanding performance applications. Precision-engineered with dimensions of Top 0.650 in. / Bottom 0.906 in. ID and Top 1.034 in. / Bottom 1.290 in. OD, the new LS/LT 1.900" Beehive Valve Spring represents the next evolution in COMP's dedication to performance and reliability. Whether for spirited street driving or high-performance builds, enthusiasts can count on COMP to deliver the technology and quality demanded by modern GM platforms.

• Beehive Valve Spring for .650" Lift at 1.900" installed height fits GM Gen III/V aftermarket, Gen IV LS7, Gen V LT, and Mopar Gen III Hemi heads. This is a great hydraulic roller spring that pairs very well with moderate street grinds.

Platform-level fitment (Ford + GM, Phase 1). We publish the engine platform a part is built for — not year-and-trim application data — so nothing here confirms a fit on a specific vehicle. Confirm fitment with us before ordering: (714) 202-7886.
