Master Mods Premium V2 Upgrade Parts by ASG is our newest line of premium V2 upgrade parts. Using refined air efficiency parts, the Master Mods line guarantees near perfect compression with any cylinder along with superior air efficiency and durability.

This is a bore-up kit. A bore-up kit has an extrusion coming off the piston head and indent in the cylinder head for the purpose of air efficiency. As a result, the piston head is NOT compatible with flat-faced cylinder heads. This will create a premature wear on the piston head and is not covered under our warranty. On the other hand, the cylinder head is compatible with flat-faced piston heads, but you could possibly suffer compression loss.
