The Multiquip RG60420 Exhaust Manifold STH-55JD is a genuine OEM exhaust manifold designed for the STH55JD. Sourced directly from Multiquip, this part meets the same specifications as the original component installed at the factory. If you are maintaining or overhauling an STH55JD, this is the correct direct-replacement manifold for the job. DHS Equipment stocks genuine Multiquip parts so you can get the right component the first time.
Key Features
- Genuine OEM Construction — Cast to the same material grade and dimensional spec as the original, ensuring proper exhaust sealing and heat management specific to this manifold application.
- Direct-Fit Replacement — Bolt pattern and port dimensions match the STH55JD exhaust outlet exactly, allowing a straightforward swap with existing hardware.
- STH55JD Compatibility — Engineered specifically for the STH55JD, so there is no guesswork about whether the part will align with your machine's exhaust system.
- Exhaust Integrity Maintained — A correctly seated manifold keeps exhaust gases routed away from the engine bay, protecting surrounding components from heat damage and carbon buildup.
- Fuel System and Engine Safety — Exhaust leaks at the manifold can allow hot gases to contact fuel lines and operator areas; replacing a cracked or warped manifold promptly is a critical safety step.
The exhaust manifold collects spent combustion gases from the engine's cylinder head and channels them into the exhaust system for safe discharge. It must withstand extreme thermal cycling — expanding and contracting with every heat-up and cool-down — while maintaining a gas-tight seal at every port and flange. When a manifold cracks, warps, or develops a leak, exhaust gases escape before reaching the muffler, resulting in increased noise, reduced engine back-pressure, potential power loss, and a serious fire or inhalation hazard if gases contact hot surfaces or the operator's environment. Replacing a damaged manifold with the correct OEM part restores proper exhaust flow and protects the engine and surrounding components from accelerated wear.
