CNC Machined Transmission Parts for Automotive Teams
Transmission teams in Charlotte need parts with tight bore fits and precise gear geometry. We machine aluminum, steel, and iron transmission components to ±0.001" on general features and tighter on critical bores. CMM inspection on every order.
Transmission Alloys
Aluminum, 4340 steel, and ductile iron with material certs.
Bore & Journal Precision
±0.0001" on critical gear bores and journal diameters.
QC Docs
CMM inspection reports on every transmission component order.
NASCAR Country Meets Modern Automotive Manufacturing
Charlotte's automotive heritage runs from NASCAR headquarters in Uptown to a booming EV supply chain — BMW's Spartanburg plant (the brand's largest global factory) is just over the state line, while Daimler Truck North America's headquarters sits in Portland but maintains Charlotte-area operations. Hendrick Motorsports, Penske, and dozens of motorsport machine shops keep precision manufacturing skills sharp across the metro.
RivCut supports Charlotte automotive suppliers with CNC machining, rapid prototyping, and the tight tolerances motorsport and OEM production programs demand.
BMW Manufacturing (Spartanburg)
