The .585” Lift COMP Cams Beehive Valve Spring Kits for GM 6.6L Duramax Diesel Engines include everything needed to upgrade from stock springs: Beehive Valve Springs, steel retainers, spring seats and valve seals. Beehive Valve Springs feature a reduced diameter at the top of the spring to allow the use of a smaller and lighter retainer, reducing overall valve train weight. The lighter valve train combined with the stronger spring allows the engine to rev higher without concerns of valve float while an increased spring rate maintains valve train stability at elevated RPM to allow the use of more aggressive camshafts. The unique ovate Beehive shape not only has higher load but is more dynamically stable than the factory spring, ensuring valve train stability at elevated RPM and boost pressures.
Able to support .585″ valve lift, this Beehive Spring Kit for ’01-’05 Duramax Diesels includes springs, retainers, seats and seals for an easy drop-in upgrade. Thanks to a unique Ovate Beehive design, this kit handles higher RPM and boost.

With a .600″ maximum lift, these Beehive Valve Springs were designed for hydraulic or Solid flat tappet cams as well as hydraulic Roller cams. They allow Big block engines to turn more RPM. COMP Cams Beehive Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehive shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Because of the unique Beehive design, the valve train can handle more RPM and more aggressive Camshaft profiles.

COMP Cams’ 26097 dual valve springs are a product of innovative design and superior craftsmanship. Engineered with state-of-the-art techniques and premium wire processing, they redefine reliability and consistency in the performance automotive aftermarket. This spring utilizes a progressive pitch coiling process that greatly improves durability and ensures safe spring life beyond traditional extreme-duty applications. The 26097 is purposed for endurance solid roller applications, with up to .800” lift at an installed height of 2.000”. They fit cylinder heads with at least a 1.549″ spring pocket. Boasting an open load of over 600 pounds, these valve springs are designed for endurance applications and optimized with newer lobe profiles in mind to achieve higher RPM and higher lift. It is similar to the new 26953 but includes more seat load and installed height for applications where the 26953 is too short. Whether you’re seeking improved dynamics, enhanced valve control, or unmatched reliability, we have the valve springs to deliver the perfect solution. Elevate your engine’s dependability and confidence on the track with COMP Cams valve springs.
Designed for endurance-race-oriented solid roller cams, 26097 fits applications near a 2.000″ installed height and a spring pocket of 1.549″. It has a 500 lbs/in rate and over 600 lbs open load for increased RPM and improved dynamics.
