Muffler Hanger Exhaust Hanger for RV — 1 Pack
Product best for: Replacement or direct fit for Cummins/Onan RV generators with 1552174 tailpipes. Suitable for straightforward installs where a single hanger is needed.
Why selected: This hanger is a direct replacement option, aligning with the common 1552174 configuration often found on older generator exhausts.
Caution: Verify tailpipe outer diameter and mounting location to ensure compatibility.
2-Pack RV Generator Muffler Hanger — Joytrace
Features: Complete dual hanger set with silver finish; eight adjustable holes for flexible mounting; carbon steel construction for corrosion resistance.
Best for: RVs needing two secure points for a generator exhaust line, especially when aligning with varying tailpipe angles are necessary.
Why selected: The dual-hanger design and multiple hole options provide adaptable installation on a range of models, improving stability and alignment.
Caution: Surface finish may show wear in harsh environments; inspect for structural integrity during routine maintenance.
Muffler Hanger Exhaust Hanger — 3 Pack
Best for: Multi-point support for RV generators, suitable for units with multiple exhaust attachment points.
Why selected: The triple-pack setup supports more complex exhaust routings and longer generator lines, reducing sag and movement.
Caution: Ensure hanger size matches the exhaust tailpipe outer diameter (1-1/2″ to 2″ range in many Onan/Cummins configurations).
1 Pack Swivel Exhaust Hanger
Best for: Flexible routing where exhaust alignment changes due to trailer hitch setups or uneven mounting surfaces.
Why selected: Swivel designs accommodate angular exhaust paths, reducing strain on tailpipes and hangers.
Caution: Confirm outer diameter compatibility (1-1/4″ to 1-3/4″ commonly supported).
2-Pack Swivel Exhaust Hangers
Best for: Rotating hangers that adapt to dynamic exhaust routes in compact RV engine bays.
Why selected: These offer universal rotation, helping installers achieve precise alignment for varied tailpipe positions.
Caution: Confirm compatibility with your tailpipe outer diameter and space constraints before purchase.
Buying Guide
What should you consider when choosing an RV generator exhaust hanger?
- Tailpipe diameter compatibility: Most hangers fit a range like 1-1/4″ to 2″ outer diameter. Measure before ordering.
- Mounting style: Swivel or fixed brackets suit different routing needs. Swivel helps around tight corners and uneven surfaces.
- Material and finish: Carbon steel with corrosion resistance is common; look for zinc or galvanized coatings for outdoor RV use.
- Number of hangers: Some installations benefit from pairs or triples for even support across long exhaust runs.
- Installation ease: Quick-connect designs and adjustable holes speed up alignment and reduce labor.
Buying considerations from multiple perspectives ensure you select a hanger that balances durability, ease of installation, and long-term performance in varied RV environments.
FAQ
- Q: Will these hangers fit all RV generator exhausts? A: Most are designed for common tailpipe sizes seen on Onan and Cummins units, but always verify outer diameter and bracket spacing before purchasing.
- Q: Are the hangers corrosion-resistant? A: Many are made from carbon steel with protective finishes; check product specifics for the coating.
- Q: How many hangers do I need? A: For simple single-tailpipe routes, one may suffice, but longer or dual-path exhausts often require two or more hangers for stability.
- Q: Can I install these myself? A: Yes, with basic hand tools and proper measurements, installation is straightforward for typical RV generator exhausts.
- Q: Do hangers affect exhaust performance? A: Proper mounting reduces movement and wear, which helps maintain exhaust integrity and reduce noise and vibration over time.
