Automotive Product Development
Custom parts, aftermarket components, and prototype tooling for automotive applications — designed for fit, function, and durability.

You're an automotive brand, aftermarket accessory company, or performance shop that needs a part engineered — not just modeled. Whether it's a custom bracket, an aftermarket accessory line, or a one-off performance component, you need parts that fit real vehicle geometry and hold up under real driving conditions.
What's different about automotive parts
Tight tolerances and fit requirements
Automotive components have to meet precise dimensional specs to integrate with existing assemblies. Off-spec parts mean fitment failures, warranty issues, and costly rework.
Tooling is expensive to get wrong
Production tooling is a real investment. Without a functional prototype to validate design and performance first, you risk locking in a design flaw at scale.
Custom parts don't exist off the shelf
Aftermarket accessories, specialized brackets, and one-off performance components require real engineering — most shops aren't equipped to handle that from scratch.
How RMA solves it
Precision design with automotive tolerances
Every component is modeled with GD&T, tolerance stack-up analysis, and real-world fit checks. We design for the assembly, not just the part.
Functional prototypes before you commit
We build and test functional prototypes with CNC machining and 3D printing before any tooling is cut — you validate performance before spending on production.
One team, concept to production
Whether it's a single bespoke bracket or a run of 500 aftermarket components, design, prototyping, and production run through the same team.
The kind of work we do for automotive clients
Custom brackets and mounts
Precision-machined or fabricated mounting hardware designed to fit an existing vehicle architecture.
Aftermarket accessory lines
Performance and accessory parts taken from concept and DFM review through a first production run.
Prototype tooling for validation
Low-volume mold tooling and cast parts to validate a design before committing to full production tooling.
What it actually costs
Design comes first for automotive parts — tooling follows once fit and function are validated.
Design
Starts around $2,000
Typically $3,000–$25,000 depending on part complexity and how many mating interfaces need to be checked.
Manufacturing Tooling
$5,000–$50,000
Depends on material and part geometry — first production runs ship in 8–16 weeks once tooling is locked.
Services we use for automotive projects
"RMA Engineering was an invaluable partner in consulting on the designs and applications for three of our recent projects.
