Industry leading manufacturer PAC makes these beehive shape ovate wire valvesprings in the USA. Perform beautifully in 3800 Series II and III engines, as well as LS engines, with higher lift applications such as aftermarket camshafts. These high load springs can be used in high performance and racing applications up to .640" lifts. These valvesprings will fit stock L36, L26, L67, and L32 cylinder heads with no machining, and fit right into stock valvespring seats.

We recommend the PAC-105 for engines with mild cams such as the INTENSE™ Stage 1x grind.
