Valve spring grade:
This is a pre order item. We will ship it when it comes in stock.

Atomic Barra performance valve springs come as a set of 24 matched to within +-1lbs spring pressure. These springs range between 80-85lbs pressure at the seat and each box comes marked this number. Matched sets make for a more consistent load across the valvetrain. That's means a quieter, smoother engine. 

These springs are suitable for fairly standard motors with increased boost. Limit boost to around 25psi. 

Stage 1 Suits fairly standard engines up to around 600hp
Stage 2 Suits built motor, upgraded turbo, higher compression, or high revving motors up to ~800hp
Stage 3 Suits motors that are streetable and pushing towards 1000hp 
Stage 4

Suits motors similar to stage 3 but with larger valves or HD rockers

Stage 5 Suits 1200+ hp motors that rev hard, have extra valvetrain weight and issues with exhaust back pressure.
