Trunk Hinges
Custom trunk, deck lid, and access-panel hinges engineered for OEM fit, motion arc, durability, packaging constraints, and repeatable performance across specialty vehicle and automotive aftermarket programs.
Mansfield Engineered Components designs and manufactures OEM universal trunk hinges, lift assists, deck lid counterbalances, and motion control assemblies for automotive and transportation programs. From concept engineering through stamping, prototyping, tooling, production, inspection, and release-based delivery, our team helps OEMs achieve reliable trunk motion, target unit costs, and scalable supply from 5,000 to 5,000,000+ components.

Custom-engineered hinge, counterbalance, prototyping, stamping, and production support for OEM trunk and deck lid programs.
Custom trunk, deck lid, and access-panel hinges engineered for OEM fit, motion arc, durability, packaging constraints, and repeatable performance across specialty vehicle and automotive aftermarket programs.
Application-specific lift assist and counterbalance mechanisms help offset lid weight, improve operator feel, support controlled motion, and reduce reliance on off-the-shelf gas spring alternatives.
In-house prototyping and engineering validation test torque profile, motion arc, hold-at-angle performance, cycle life, and tactile feel before tooling and production release.
Progressive die stamping, single-stage stamping, fabrication, spring manufacturing, riveting, fastening, and assembly support precision trunk hinge production at OEM volume and cost targets.
Tooling transfer, supplier resourcing, first-article inspection, and production validation help OEMs maintain continuity when a hinge supplier exits, underperforms, or goes end-of-life.
Flexible production supports 5,000-unit specialty runs through 5,000,000+ component programs, with strategic inventory and release-based shipping aligned to customer schedules.

We begin with the trunk lid geometry, weight, packaging envelope, attachment points, target motion arc, load expectations, durability requirements, and unit cost goals so the hinge concept is engineered around the OEM product.
OEMs choose Mansfield for custom engineering, manufacturing depth, and dependable long-term supply.
No catalog-only approach; every hinge is designed around application-specific motion and cost goals.
Over 250,000 motion control components ship weekly from a 200-person manufacturing team.
Single-source responsibility covers design, prototyping, tooling, production, inspection, packaging, and delivery.
Same-day customer response and strategic inventory support reliable releases and on-time delivery.
Experienced leaders guiding OEM hinge programs from concept to production.
An OEM universal trunk hinge is a custom or platform-based hinge assembly designed for trunk lids, deck lids, access covers, or specialty vehicle storage compartments. For OEM programs, the hinge must match the lid weight, geometry, mounting points, motion arc, durability expectations, and production cost target rather than simply fitting a generic aftermarket application.
