Genie & JLG Diesel Boom Lift & Telehandler DOC Rebuild

New England Supply House rebuilds the diesel oxidation catalyst (DOC) on Genie and JLG diesel boom lifts and telehandlers — send us your core and we’ll rebuild it with new internals, built to meet EPA emissions standards, for a fraction of OEM cost.

How the rebuild works

Core exchange is required — we rebuild your catalytic converter, so we need your core to complete the job.

1. Get a quote. Tell us your machine’s model, engine, and serial, and we’ll reply with a price.
2. Ship us your catalytic converter core (with tracking and insurance).
3. We rebuild it with new internals, built to meet EPA emissions standards.
4. We ship it back — usually within 3–5 business days of receiving your core.

Which Genie & JLG lifts have a rebuildable DOC

Tier 4 Final diesel Genie and JLG boom lifts and telehandlers under about 74 hp run a Deutz 2.9L or Kubota diesel with a standalone diesel oxidation catalyst (DOC) — DOC-only, no DPF/DEF on most sub-56 kW units.

Electric scissor and mast lifts have no catalyst. Larger telehandlers above 74 hp pair the DOC with a DPF. We rebuild the DOC. Not sure which you have? Call 774-701-6374 with your engine model and serial and we’ll confirm you have a rebuildable core before you ship.

Pricing: Off-road converter rebuilds are quoted per engine and converter — call 774-701-6374 for your price.
