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

Tight tolerances and fit requirements
Automotive components must meet precise dimensional specs to integrate with existing assemblies. Off-spec parts cause fitment failures, warranty issues, and costly rework.
Prototyping before tooling investment
Full production tooling is expensive. Without functional prototypes to validate design and performance, companies risk locking in design flaws at scale.
Sourcing parts that don't exist off the shelf
Custom applications — aftermarket accessories, specialized brackets, one-off performance components — require custom engineering that most shops aren't equipped to handle.
How RMA solves them
Precision design with automotive tolerances
Every automotive component we design 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 production commitment
We build and test functional prototypes using CNC machining and 3D printing before any tooling is cut. You validate performance before spending on production.
Custom parts from concept to production
Whether it's a single bespoke bracket or a run of 500 aftermarket components, we handle design, prototype, and production from one team.
What we build for automotive
Custom Brackets & Mounts
Precision-machined or fabricated mounting hardware designed to fit existing vehicle architectures.
Aftermarket Components
Performance and accessory parts designed for aftermarket sale — from concept and DFM through production runs.
Prototype Tooling
Low-volume injection mold tooling and cast parts for pre-production validation of plastic and metal automotive components.
Interior & Trim Parts
Custom interior components, panels, and trim pieces designed to OEM fit and finish standards.
Functional Assemblies
Multi-part assemblies including sub-assemblies, fastener packages, and integration with existing systems.
CNC Machined Parts
High-precision metal and plastic components machined to tight tolerances for under-hood and structural applications.
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. Their expertise and guidance helped ensure that every detail was executed flawlessly. Our customers were absolutely blown away with the end results, and expectations were exceeded across the board. RMA's team is friendly, professional, and extremely easy to work with. I look forward to collaborating with them again on future projects and highly recommend their services."
