2015-2024 Ford F-150 UMI Performance 3/4in Extended Length Leaf Spring Pin Kit

This listing covers the exact UMI Performance hardware kits - other configuration identified as Ford F-150 UMI Performance 3/4in Extended Length Leaf Spring Pin Kit.

Catalog fitment covers the listed 2015-2024 Ford F-150 applications. Exact year and submodel combinations appear in the fitment table below; compatibility must not be inferred for every trim across the full range.

Manufacturer-supplied details include Four 4140 CrMo pins, machined to extended length, so the leaf spring centers properly instead of binding against a pin that can't reach; Sized for trucks running a lowering system or pinion angle shims, exactly the setups where the factory pin comes up short; Solves a centering problem the factory pin can't handle once ride height or pinion angle has been changed; Made in the USA.

UMI doesn't spell out the install process, only that the four extended pins replace the factory locating pins that center the leaf spring. This is a targeted fix, not a broad upgrade: if your F-150 isn't already running a lowering system or pinion angle shims, the extra pin length doesn't do anything for you.

Listed specifications include Part type: Hardware Kits - Other; Quantity: 4 locating pins; Material: 4140 CrMo; Country of origin: Made in USA.

Use manufacturer part number 6577 to identify this exact UMI Performance configuration. Match the full part number, vehicle application, position, dimensions, material, finish, and included components before ordering.

Orders over $99 ship free by ground to the lower 48 states. Alaska, Hawaii and Canada are not included; shipping to those addresses is calculated at checkout. Some oversize or heavy parts (long-tube exhausts, bumpers, full lift kits) go freight instead of parcel: free to a commercial address with a loading dock, and residential freight delivery carries an additional charge.

When it ships
