SeSicWe Muffler & Exhaust Hanger for RV and Onan Generators — Pack of 3, 1-1/2 in Tailpipe Fit, Heavy-Duty Iron

If your RV or onboard generator has a worn or broken exhaust hanger, this three-piece SeSicWe replacement kit restores support and reduces vibration for a safer, quieter tailpipe fit. Built from durable iron and shaped for RV-style installations, the hangers are compatible with popular models including Forest River, Sunseeker Class C, Odyssey chassis and Onan 2500, 4000, and 5500 series generators. The flexible bracket segment speeds installation and fits standard 1-1/2" outer diameter exhaust tailpipes.

How will this hanger improve my RV or generator exhaust stability?

These hangers remove sagging and excessive movement by anchoring the tailpipe to the vehicle frame or generator housing. Restoring a secure mount lowers the risk of exhaust contact with sensitive components and reduces noise caused by metal-on-metal movement.

• Firm iron construction resists bending under load.
• Designed for RV-style mounting points and generator frames.
• Reduces vibration and prevents tailpipe misalignment.

Will the SeSicWe hanger fit my Onan 2500, 4000, or 5500 generator?

Yes — the hanger is made to replace OEM part numbers 1552174 and 155-2174 used on many Onan generator models and compatible RV applications. Its opening and flexible bracket section are sized for the typical 1-1/2" outer diameter tailpipe found on these units.

• Direct replacement of 1552174 / 155-2174.
• Tailpipe aperture fits 1-1/2" outer diameter exhaust pipes.
• Works with Onan 2500, 4000, 5500 and common RV exhaust layouts.

How easy is installation and what tools are required?

Installation is straightforward for most DIYers and professional technicians: the flexible portion of the bracket allows you to position and secure the hanger quickly without complex bending. Typical tools include a ratchet or wrench set and basic fasteners — replacement of the old hanger usually takes a few minutes per unit.

• Flexible bracket segment for fast alignment and attachment.
• Fits common RV frame mounts and generator mounting holes.
• No specialized tools needed beyond standard hand tools.

What material and durability benefits does this exhaust hanger offer?

Manufactured from sturdy iron, the SeSicWe hanger offers reliable long-term support in the high-heat, vibration-prone environment of vehicle and generator exhaust systems. The heavy-duty design resists deformation and maintains proper tailpipe position even under repeated thermal cycling and road vibration.

• Iron construction for strength and longevity.
• Engineered to withstand road and engine vibration.
• Pack of three supports multiple hang points or spares for future maintenance.

Who is this for: RV owners, fleet maintainers, and generator technicians who need a dependable replacement for worn exhaust hangers on Forest River, Sunseeker Class C, Odyssey platforms, and Onan 2500/4000/5500 generators. If you want a direct-fit, heavy-duty iron hanger that matches OEM part numbers 1552174 and 155-2174 and fits a 1-1/2" outer diameter tailpipe, the SeSicWe pack of three provides a cost-effective, durable solution for stabilizing exhaust systems and minimizing vibration and noise.
