We offer 5 stages of ESSLINGER SPORT CAMS performance VCT camshafts for 2.0L/2.5L Mazda and 2.5L Ford Duratec engines (6 tooth cam trigger). These cams cover a wide range of applications from mild pump gas bolt-on equipped engines up to wild all-out high rpm track terrors!

Stage 1 cams are for unopened 2L & 2.5L n/a engines and also work extremely well in turbo engines
Stage 2 cams work well in unopened Hot-Street 2L & 2.5L n/a engines
Stage 3 cams are similar in duration to Stage 2 but require aftermarket pistons with deeper valve reliefs.
Stage 4 cams for high compression street engines that have aftermarket pistons with deeper valve reliefs
Stage 5 cams are for racecars with 12:1 compression or higher

*** Stage 1 & 2 cams are can be run with the OEM valvesprings. Stage 3 through 5 require valvespring kit found here: SPORT CAMS Ti Retainer Valvespring Kit ***
