CNC Machined Powertrain Housings for Automotive Teams
Powertrain teams in Minneapolis need housings with precise bearing bores, flat mating surfaces, and zero porosity. We machine aluminum and iron powertrain housings to ±0.0001" on critical bores. CMM inspection and material certs on every order.
Powertrain Materials
Aluminum, ductile iron, and gray iron with material certs.
Bearing Bore Precision
±0.0001" on critical bearing and journal bores.
QC Docs
CMM inspection reports on every powertrain housing order.

What Minneapolis Automotive Buyers Should Know
Polaris and Donaldson sourcing teams expect ISO 9001-aligned suppliers with statistical process control
verify your shop runs SPC on critical dimensions.
Twin Cities winters can delay freight
build 2-3 days of buffer into your JIT delivery schedule for December through March shipments.
Powersports machining demands cosmetic surface finishes on exposed aluminum
confirm your shop offers bead blasting, anodizing, and tumble-deburring in-house or through vetted partners.
