What we do

Double D Mechanical provides heavy-duty truck and equipment repair across Alberta. We specialize in engine rebuilds, offering OEM-level warranty discipline — and we are an AFA Industries and Diesel Power Source distributor so parts and knowledge stay on the same invoice.

• ▸ Diesel engine in-frame & out-of-frame rebuilds
• ▸ Cylinder heads, turbos, aftertreatment diagnostics
• ▸ Driveline, hydraulics, and chassis work (job-dependent)
• ▸ Fleet maintenance programs & priority scheduling
• ▸ Field diagnostics where travel makes sense
• ▸ Parts quoting for AFA coverage — see AFA products
