COMP Cams GM LS Engine Billet Aluminum Valve Covers

Steel Valve Locks‚ 511-16 Valve Seals‚ 4861-16 Spring Seats. This Beehive Valve Spring Kit for LS engines is designed for hydraulic Roller cams and includes carefully matched Beehive Springs, retainers, locks, Seals and spring seats. With a .625″ maximum lift, these 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.

A high lift Cam in a performance street vehicle can offer up great sound and excellent performance. But if your car or truck has power brakes, a minimum of 16 inches of vacuum is critical to proper brake booster operation, something not always present if your Camshaft features enhanced overlap. The COMP Cams Electric Vacuum Pump ensures that your vacuum stays between 18 and 22 inches so you never have to worry whether your brakes will be there when you need them. Triggered by a vacuum switch included in the kit, the COMP Cams Electric Vacuum Pump requires a 12V negative ground system and only operates when vacuum drops below 18 inches of vacuum and then turns off over 22 inches of vacuum. The kit includes all of the parts necessary to install the unit along with wiring, hoses and brackets. The system utilizes a highly efficient electric pump, relay switch and distributor with vacuum switch, which should be mounted close together for the most effective performance.
Our electric vacuum pump kit operates off a 12v negative ground electrical system which ensures that the vacuum for your power brakes never drops below 18 in/hg.
