Morbark down on power or in a Tier 4 derate? We rebuild the converter in your original housing for about half the cost of OEM — core exchange, back in 3–5 business days.
Morbark chippers on GM, Power Solutions International, and CAT power all rely on a healthy catalytic converter. When it plugs, you feel it — bogging under load, an emissions code, or a derate. D&S rebuilds your existing converter with a fresh substrate in the original housing, built to meet EPA emissions standards and backed by a warranty against manufacturing defects — for about half of a new OEM unit.
