Billet Performance Parts from Your CAD File
Aftermarket performance parts demand precise O-ring grooves, leak-free fluid passages, and consistent cosmetic finishes. A fuel rail with an injector bore that is off by 0.002" leaks fuel under boost pressure. We machine billet aluminum 6061-T6, 7075-T6, and stainless steel to tolerances as tight as ±0.0005". Every part is dimensionally inspected and ready for your product line.
Billet Materials
We machine billet aluminum 6061-T6 for fuel rails, catch cans, and intake spacers. 7075-T6 for turbo flanges. 304 stainless for exhaust-side components. Titanium for shift knobs.
Fluid-Tight Precision
We hold ±0.0005" on O-ring grooves, injector bores, and sealing surfaces. Your fuel rails and catch cans seal perfectly under boost pressure and vibration.
Finish-Ready Quality
Parts machine to anodize-ready surface quality. No secondary cleanup needed. Color anodize, bead blast, polish, and brushed finishes available for retail-ready products.

Custom thread & finishServing the Performance Aftermarket Industry
The US automotive aftermarket is a $51 billion industry, driven by enthusiasts, racing teams, and performance brands building products for modified vehicles.
Every aftermarket brand needs a reliable CNC machining partner for prototyping new products and running production batches. The market demands consistent quality, cosmetic finishes, and the ability to scale from 10-piece prototypes to 5,000-piece production runs.
Whether you are launching a new fuel rail design or scaling production on your catch can line, we want to be your machining partner. Instant AI pricing the moment you upload your file.
SEMA Brands & Exhibitors
Performance parts companies building products for the largest automotive aftermarket trade show. Need fast prototypes before SEMA and reliable production after launch.
Turbo Kit Builders
Companies building complete turbo kits need consistent flanges, intake piping adapters, and blow-off valve mounts. Repeat orders with tight tolerances for bolt-on fitment.
Fuel System Specialists
Fuel rail and fuel system companies need precision injector bores, O-ring grooves, and AN fitting ports. Every bore needs to be identical for consistent fuel delivery.
E-Commerce Performance Brands
Online performance parts retailers selling direct to enthusiasts. Need retail-ready finishes, consistent quality, and the ability to scale production as demand grows.
Built for Aftermarket Brands
Aftermarket parts need a shop that understands cosmetic quality, product consistency, and production scaling.
Anodize-Ready Surfaces
Parts machine to smooth, consistent surfaces ready for color anodize without secondary cleanup. Your products look retail-ready straight from our shop.
Prototype to Production
Start with 5 prototypes for fitment testing. Scale to 500 or 5,000 pieces for your product launch. Same shop, same quality, same contact person.
Fluid-Tight Machining
O-ring grooves, injector bores, and AN ports machined to tolerances that seal under boost pressure. No leaks, no rework, no warranty claims.
Fast Prototype Turnaround
