Emission System Components

Smarter Fabrication for Faster Performance

At Wenthe-Davidson, we don’t just make parts. We build the backbone of modern emission control systems. From diesel engines to off-road vehicles, our components help keep your equipment compliant, efficient, and moving forward. Fast.

We’re not just engineers. We’re expert fabricators. That means we deliver real-world solutions, lean processes, and rock-solid reliability, all at the speed your market demands.

What We Make

Diesel Particulate Filters (DPFs)

Trapping soot. Cutting emissions. Keeping you in compliance. Our precision-fabricated housings and assemblies for DPF systems are built for long-lasting performance under pressure.

SCR Systems (Selective Catalytic Reduction)

SCR systems cut NOx emissions—ours do it better. We craft custom brackets, tubes, and housings that integrate seamlessly, helping your DEF systems deliver clean results fast.

EGR System Components

EGR components require precision—tight tolerances, clean fits, and no margin for error. That’s where we shine. We make sure your exhaust gas recirculation is smooth, durable, and built for the long haul.

Diesel Oxidation Catalyst (DOC) Parts

From mounting brackets to full enclosures, we support your DOC systems with parts that fit right, ship fast, and perform reliably.
