These precision machining tracks share similar processes, materials, and quality standards.
For motorsports, the most common materials are 7075-T6 aluminum (high strength-to-weight), 4130 chrome-moly steel (roll cages, brackets), titanium Ti-6Al-4V (suspension, connecting rods, exhaust), and 4340 steel (crankshafts, axles). We also machine Inconel 625/718 for high-temperature exhaust components and PEEK for lightweight brackets.
Yes. We machine custom suspension uprights, control arms, knuckles, and shock absorber components from 7075-T6 aluminum and 4340 steel. Components are 5-axis machined in single setups for maximum accuracy. We hold bearing bore tolerances of ±0.005mm and provide CMM inspection reports for all critical suspension geometry.
We machine billet brake calipers (6061-T6 or 7075-T6), master cylinder bodies, clutch baskets, and pedal assemblies. All brake components are pressure-tested to 2000 PSI before shipping. Internal bore finishes meet or exceed OEM specifications with documented inspection.
We machine custom brackets, mounts, and adapter plates from aluminum, steel, and titanium. Whether it's a spoiler bracket, fuse box mount, intercooler bracket, or ECU mounting plate, we work from your CAD or sample part. Most brackets can be turned around in 3-5 working days.
Yes — pocketing and weight reduction is a common service. We machine material removal profiles on non-structural areas, leaving ribs and gussets for stiffness. Weight reduction is typically 20-40% depending on the part geometry. We advise on structural integrity and can provide FEA-validated designs if needed.
Every motorsports part ships with dimensional inspection reports for all critical features. For safety-critical components (suspension, brakes, steering), we provide material certificates, hardness testing reports, and crack detection (dye penetrant or magnetic particle) certification. Full CMM reports are available for any part.
Every gram saved translates to lap time. Aluminum 7075-T6 and titanium Grade 5 are the workhorses, with selective use of magnesium for non-structural brackets and covers.
Motorsport components see extreme cyclic loading. TruPart recommends stress relieving raw stock before rough machining, then a second stress relief before finishing critical dimensions.
Thin-wall machining of aluminum and titanium brackets requires specialized workholding and vibration damping. TruPart achieves wall thicknesses down to 0.8mm in aluminum with consistent results.
A smooth surface finish Ra ≤0.8μm on stressed sections dramatically improves fatigue life. Avoid sharp internal corners — specify radiused fillets to distribute stress.
Many motorsport alloys benefit from post-machining heat treatment. Inconel and titanium parts can be aged or stress relieved after rough cutting to stabilize dimensions before final pass.
