Chevrolet Performance .560 Lift LS Valve Springs Beehive GM LS6 LS2 LS3 19420455

***Sold as a set of 16. No extras are included, just springs! 
These 19420455 Chevrolet Performance Valve Springs are OEM replacements for LS6 and LS3 valve springs. Over the years they have been yellow, blue, and now they're brown. 
They are popular for most low-lift LS camshafts up to .560" lift (but will go to .570"). 
You can reuse your factory retainers/keepers. Seal replacement is recommended if you have high mileage. These will use the stock "top hat" style seals which sandwich between the head and the spring.
