Product Description
Wake up your 6.7L Cummins with the Industrial Injection S300 SX-E 62/74 single turbo kit (.91 A/R). This 2nd-gen-style swap centers the turbo on a high-flow T4 manifold for quicker spool, lower EGTs, and rock-solid reliability versus the factory VGT. Ideal for street/strip builds targeting strong, usable power with clean drive pressure.
Fitment
- 2007.5–2009 Dodge Ram 2500/3500 6.7L Cummins (late-3rd gen), manual or automatic

FAQ
How much power will a 62/74 .91 A/R support?In typical 6.7L builds with fuel and tuning, the 62/74 SX-E .91 A/R is commonly used in the ~550–600 HP range with excellent drivability.
What’s the advantage of the 2nd-gen-style (center mount) layout?Center mounting improves service access and manifold flow distribution, lowers drive pressure, and simplifies the system compared to the factory VGT layout.
Do I need head studs?They’re strongly recommended once you raise boost or tow heavy, to maintain head-gasket integrity.
Is an HX40 downpipe included?Yes, this kit uses an HX40-style outlet and includes the downpipe; we also recommend a fresh HX40 v-band clamp for a perfect seal.
