Industrial Injection 22C402 Silver Bullet 66mm Turbocharger Kit for 6.7L Cummins

The Industrial Injection 22C402 Silver Bullet 66mm Turbocharger Kit is a high-performance single turbo upgrade engineered specifically for 2013–2018 Dodge Ram trucks equipped with the 6.7L Cummins diesel engine (does not fit 2013 Ram 2500). Designed to replace the factory variable geometry turbocharger (VGT), this kit delivers a broad, aggressive power curve ideally suited for trucks running fueling modifications or aggressive tuning.

The Silver Bullet 66 builds on the proven PhatShaft platform with key upgrades centered around the advanced 74mm turbine wheel — a major leap in turbine trim design technology. This turbine transfers exhaust gas energy more efficiently, resulting in lower exhaust gas temperatures (EGTs), quicker rotor acceleration, reduced compressor surge, and a wider, more usable power band across the RPM range.

Key Features:

• 66mm extended tip forged milled compressor wheel for high-flow, high-efficiency air delivery
• 74mm turbine wheel — next-generation trim design for superior exhaust energy transfer and lower EGTs
• 14cm exhaust housing with modified exhaust nozzle angle, maximized wastegate ports, and enlarged wastegate chamber for full wastegate travel
• 360-degree thrust bearing for enhanced durability under high-load conditions
• Dual grooved high-performance bearings for long service life
• Polished compressor housing — clean, professional appearance
• Adjustable boost elbow included for boost pressure tuning flexibility
• Replaces the factory VGT for improved reliability and performance headroom
