Precision methods and finish quality

We emphasize accuracy, repeatability, and clean fitment across every custom order. Services include custom laser cutting for crisp profiles and consistent hole patterns. If we identify a compatible catalog part that meets your needs faster or more affordably, we’ll recommend it and adapt the design as appropriate.

How our custom process worksโ€‹

We keep the process simple and transparent so you can focus on the build.

1. Share your idea and Timeline

Send drawings, sketches, or reference dimensions, plus quantity targets and timing. If an existing part is close, include the SKU or a link.

2. Feasibility review

We'll confirm details, flag any risks, and suggest whether a catalog solution or custom path fits best.

3. Quote

Your quote outlines scope, unit pricing by quantity, and estimated lead time. If details are missing, we'll follow up for clarity.

4. Build

We manufacture most parts in-house (approximately 90%) with remaining work completed locally for speed and quality.

5. Ship or pick up

Orders ship nationwide. Same-day dispatch is available for in-stock items; completed custom orders ship promptly upon finish. Walk-in pickups are welcome at our Spring Lake showroom.

What to include with your request

  • Part description and function
  • Dimensions or a drawing/print; photos help for complex shapes
  • Material preferences if known; otherwise we can suggest options
  • Vehicle details, when relevant
  • Quantity needed (prototype, short run, or ongoing)
  • Any special constraints
