The Multiquip 18321ZJ1801 Muffler Protector is a genuine OEM component designed for AR13HA/HAR, AR13H, and AR13HC asphalt ride-on rollers. As an authorized Multiquip parts source, DHS Equipment supplies this part direct — so you can be confident you're getting the correct fitment for your machine. The 18321ZJ1801 installs as a direct replacement on compatible AR13 series rollers, restoring proper heat shielding and operator protection around the exhaust system. If your existing muffler protector is cracked, missing, or heat-damaged, this genuine OEM replacement brings your roller back to proper working condition.
Key Features
- Genuine OEM Heat Shield Construction — Manufactured to Multiquip's original material and dimensional spec, ensuring the protector wraps and mounts correctly around the muffler housing without gaps or misalignment.
- Direct Bolt-On Replacement — Engineered to match the original mounting points on AR13 series asphalt rollers, so installation requires no reworking of brackets or hardware.
- AR13 Series Fitment — Confirmed compatible with AR13HA/HAR, AR13H, and AR13HC ride-on asphalt roller models.
- Sustained Heat Containment — Keeps exhaust heat directed away from surrounding components and personnel, helping protect wiring, hoses, and operator contact zones during extended paving runs.
- Burn and Contact Hazard Mitigation — On asphalt compaction equipment where operators and ground crew work in close proximity to the machine, a structurally sound muffler protector is an essential safety barrier — not a secondary concern.
The muffler protector is a heat shield that surrounds the exhaust muffler on engine-powered equipment. Its primary role is to contain radiated heat from the muffler, preventing accidental burns to personnel and protecting nearby fuel lines, hydraulic hoses, and electrical components from heat damage. On ride-on asphalt rollers like the AR13 series, where operators sit close to the engine bay and ground crews work nearby, a damaged or missing protector creates a genuine contact burn risk. A worn or broken shield can also allow heat to concentrate in areas not designed to handle it, accelerating wear on adjacent components over time.
