UMI Performance 2402-B Tubular K-Member for Coil-Over Applications | Black Powdercoat

The UMI Performance 2402-B is a direct bolt-in tubular K-member engineered for street, drag strip, and autocross use. Shedding 20 lbs compared to the factory unit, this K-member is purpose-built for coil-over setups and delivers a significant front-end weight reduction without sacrificing structural integrity. Fabricated in Philipsburg, PA using 100% USA-sourced materials, the 2402-B reflects UMI's commitment to precision manufacturing and real-world performance testing.

Construction & Design:

• Dual tube lower section — 1-1/2" diameter DOM tubing provides superior strength over single-tube competitors
• CNC-machined 3/16" thick mild steel engine and suspension mounts with precision-machined mounting pads for factory clamshell and engine mounts
• Strong boxed mounting points locate both factory and aftermarket suspension components
• CNC-machined lightening holes in mounting plates reduce weight without compromising strength
• Tubular construction adds clearance for aftermarket exhaust systems
• MIG and TIG welded for clean aesthetics and maximum weld penetration
• Jig-built for accuracy — ensures consistent fitment and no-hassle installation

Key Features:

• Saves approximately 20 lbs of front-end weight versus stock K-member
• Direct bolt-in fitment — compatible with factory, UMI, or other aftermarket A-arms
• Modular design supports coil-over use as delivered; convertible to factory-style springs with spring perch kit P/N 2405
• LSX engine compatible with the addition of motor mount adapters P/N 2409

Important Notes:

• Coil-over use only: P/N 2402-B is designed exclusively for coil-over setups and does not accept factory springs as delivered. Factory spring compatibility can be added by purchasing spring perch kit P/N 2405.
