The Multiquip 513520 Muffler Base Extension AR 13H is a genuine OEM component designed for AR13H, AR13HA/HAR, and AR13HC asphalt ride-on rollers. As a direct Multiquip OEM part, 513520 is manufactured to the same specifications as the original component installed at the factory, ensuring a correct fit without guesswork. This part ships directly through DHS Equipment, an authorized Multiquip parts dealer, so you can be confident you are receiving an authentic replacement sourced straight from the manufacturer's supply chain. If your roller's exhaust system shows heat damage, corrosion, or structural failure at the base extension, replacing it promptly with the correct OEM part protects the surrounding components and keeps the machine running safely.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards for the AR 13H exhaust system, not an approximation.
- Exact-Fit Replacement — Engineered to bolt directly into the existing muffler assembly mounting points on compatible AR-series rollers without alteration.
- Confirmed Fitment — Verified for AR13H, AR13HA/HAR, and AR13HC asphalt ride-on roller models.
- Exhaust Integrity — A sound muffler base extension properly channels exhaust gases away from the operator and machine components; a cracked or corroded extension can allow heat and exhaust to migrate into the engine bay.
- Operator Safety Compliance — Maintaining an intact exhaust base extension is critical to keeping exhaust fumes directed away from the operator platform on ride-on equipment.
- Authorized Source — Sold by DHS Equipment, a verified Multiquip OEM parts dealer, with part number 513520 confirmed against current Multiquip parts documentation.
The muffler base extension serves as the structural and thermal interface between the engine's exhaust outlet and the muffler assembly. It channels hot exhaust gases from the engine into the muffler body while providing a stable mounting foundation that absorbs vibration and thermal cycling during operation. When this component cracks, corrodes, or loses structural integrity, exhaust gases can escape at the connection point, exposing nearby wiring, hoses, and the operator to excessive heat — and the muffler itself may become loose or misaligned, accelerating wear across the entire exhaust system.
