Description

Interstate-McBee M-5290118 S400 T6 5" Exhaust Outlet V-Band Clamp – Popular for 24V 5.9L Cummins Builds

Heavy-duty 5.0" V-band (Marmon) clamp designed for turbo and exhaust connections. Ideal for S400 T6 turbine outlets using a 5" downpipe and widely used across Cummins and other diesel platforms that require a 5" V-band joint. Stainless construction and OEM-style dimensions deliver a secure, leak-resistant seal.

  • S400 T6 compatibility: Pairs with 5" outlet flanges common on S400/medium-frame turbos.
  • Universal 5" application: Works anywhere a 5" V-band clamp is specified (turbo outlet, aftertreatment joints, etc.).
  • Stainless & serviceable: Corrosion-resistant band with service-friendly fastener.
  • Aftermarket value: Interstate-McBee quality at a fraction of many OEM prices.

Vehicle Fitment

This is a universal 5" V-band clamp. Fitment depends on the turbo/exhaust hardware in your build.

  • Popular build usage: 1998.5–2002 Dodge Ram 2500/3500 5.9L Cummins (24-Valve) when running an S400 T6 turbo with a 5" downpipe.
  • Other common applications: Medium-frame turbos (e.g., S400/HT60/HT3B families) and Cummins heavy-duty/aftertreatment joints that specify a 5" V-band.

Install Notes

  • Verify flange OD and seating style (Marmon profile) before installation.
  • Ensure mating flanges are clean, aligned, and fully seated before tightening.
  • Tighten evenly; re-torque after initial heat cycle to maintain a proper seal.

FAQ

Will this fit my S400 T6 turbo?
Yes—if your turbine outlet uses a 5" Marmon/V-band flange. Many S400 T6 housings do. Measure your flange OD (≈5.75" to 5.91") to confirm.
Is this clamp stainless?
Yes. The band is stainless to resist corrosion in high-heat exhaust environments.
Does this include the mating flange or gasket?
No—this listing is for the clamp only. V-band joints typically seal metal-to-metal when properly aligned and torqued.
Will it work on a stock 24V 5.9L Cummins?
This is a universal clamp. It’s commonly used on 24V builds running an S400 T6 turbo and a 5" downpipe. Stock hardware may use different sizes—measure before ordering.
