When it comes to heavy-duty reliability, the 201V96601-0586 Supercharger Return Pipe Gasket (MC11) stands as a definitive upgrade for your powertrain. Engineered with precision, this gasket eliminates leak paths and maintains optimal boost pressure, ensuring your engine breathes effortlessly. As a critical component for Howo/Sitrak truck parts, it guarantees seamless integration with the MC11 series, delivering uncompromised sealing even under extreme thermal cycles. Whether you are overhauling a fleet or performing routine maintenance, this OEM-grade gasket redefines durability and saves costly downtime—truly a game-changer for professionals who demand excellence.
Manufactured from high-temperature fluorocarbon, the gasket resists oil degradation and pressure spikes. The precision-molded design matches the MC11 flange perfectly, eliminating blow-by and maintaining consistent supercharger response.
By securing the return pipe connection, this gasket ensures uninterrupted boost pressure, translating to consistent torque and fuel efficiency. Drivers experience smoother acceleration and reduced turbo lag.
Tested over 500 thermal cycles, the material retains elasticity and resists hardening. Downtime is drastically reduced, and the gasket outlasts conventional rubber alternatives by 3x.
Direct replacement for Howo and Sitrak MC11 engines. The 201V96601-0586 meets all factory specifications, ensuring a perfect fit without modifications—a true plug-and-play solution.

The gasket seats directly onto the supercharger return pipe flange. Clean the mating surfaces thoroughly, apply a thin film of engine oil for lubrication, and torque the bolts to 28 Nm in a star pattern. No additional sealant is required.
Compatible with all Howo T7H, Sitrak C7H, and MC11-powered chassis. The 201V96601-0586 replaces older gasket versions without any adapter plates.
Users report a 4–6% improvement in boost consistency, especially under high-load conditions. The return pipe sealing also reduces oil mist, keeping the turbocharger vane cleaner and extending its life.
By eliminating leaks, the engine maintains optimal air-fuel ratio, which directly translates to lower particulate emissions and smoother idle quality.
Every batch of the 201V96601-0586 undergoes hardness, tensile, and compression set tests per ASTM D2000. The FKM compound retains 98% of its original shape after 1000 hours at 180°C.
Salt spray and corrosion resistance exceed 500 hours without pitting, ensuring reliability in humid or coastal environments.
Field-tested in long-haul trucks across Europe and Asia, this gasket has accumulated over 2 million cumulative miles with zero returns. Fleet operators praise its drop-in fit and lasting seal.
The MC11 platform benefits from reduced oil consumption, and the gasket maintains its clamping force even after 200+ thermal shock cycles.
This gasket fits Howo T7H, T5G, and Sitrak C7H, C5H series equipped with MC11.260, MC11.360, MC11.440 engines. Also suitable for Sinotruk chassis with MC11 powertrain.
Always verify your engine serial number; the 201V96601-0586 is the exact OEM replacement for all 2016+ MC11 builds.
For a complete overhaul, pair with the intake manifold gasket (201V96602‑0587) and turbo oil return line seal. The combination ensures zero leaks across the entire forced induction system.
We recommend replacing the gasket every 300,000 km or during any supercharger service to maintain peak efficiency.
Direct from the original manufacturer, this gasket offers the same fit and finish as dealer parts but at a fraction of the cost. No compromise on materials or production standards.
Backed by a 12-month warranty against defects, the 201V96601-0586 gives peace of mind that only premium components can provide.
Reduce unplanned maintenance and keep your trucks on the road. The gasket’s superior sealing contributes to lower oil consumption and fewer DPF regenerations, saving fuel and reducing emissions.
Fleet managers report an average ROI of 8:1 within the first year due to reduced shop labor and extended component life.
The 201V96601-0586 Supercharger Return Pipe Gasket (MC11) is more than a replacement part—it is an investment in reliability. With its robust FKM construction and exacting tolerances, it upholds the legacy of Howo and Sitrak engineering. Whether you are a workshop technician or a fleet owner, this gasket delivers the performance and longevity that modern logistics demand. Choose the gasket that professionals trust, and experience the difference in every mile.
