International | Navistar

At American Radiator in Des Moines, Iowa, we specialize in precision-engineered DPF & DOC clamp kits tailored for International/Navistar heavy-duty engines. Whether you’re servicing an International LT Series, ProStar, or I-Series truck, the right clamp kit is essential to maintain the performance and emission compliance of your exhaust after-treatment system.

A secure seal between your diesel particulate filter (DPF) or diesel oxidation catalyst (DOC) and adjoining exhaust components prevents leaks, error codes, and unchecked back-pressure. Our International/Navistar clamp kits include high-grade stainless steel clamps, specially designed gaskets, and installation hardware crafted for optimal fit and durability in rugged use.

For fleet managers, owner-operators, and techs serving fleets across Iowa and the broader Midwest, our local stock and nationwide shipping provide fast access to trusted emission system hardware. With expert parts matching and durable build quality, choose American Radiator for reliable International/Navistar DPF & DOC clamp kits—designed for precision, built for the road, and supported by Midwest-based expertise.
