Product Details

The UMI Performance 2403-B Tubular K-Member is a direct bolt-in replacement subframe engineered for high-performance street, drag strip, and autocross applications. Weighing 20 lbs less than the factory unit, this K-member immediately reduces front-end weight and puts your existing horsepower to work. Every unit is MIG and TIG welded, CNC machined, and jig-built in Philipsburg, PA — USA for precision fitment and no-hassle installation.

Key Features:

  • 20 lbs lighter than the factory K-member for immediate weight reduction
  • Double tube construction using 1-1/2" diameter DOM tubing for superior strength and rigidity
  • 3/16" thick mild steel engine and suspension mounts with CNC-machined lightening holes
  • LSX engine compatible — allows installation of any LSX engine without additional modifications; fabricated motor mounts bolt directly to precision-machined mounting pads
  • Modular design — retains factory spring pockets for stock spring and strut use, or remove pockets to convert to coil-overs; compatible with LS motor mount stands
  • Works with factory, UMI, or other aftermarket A-arms as well as factory or aftermarket springs
  • Tubular construction provides added clearance for aftermarket exhaust systems
  • Available in durable red or black powdercoat finish
  • CNC machined and jig-built for repeatable, accurate fitment
  • Manufactured with pride in Philipsburg, PA — USA

Compatibility Notes:

  • Designed around the LS1 oil pan; also compatible with the Holley 302 oil pan. Other oil pan configurations may not clear — verify fitment before installation.
  • Can be used with a factory SBC engine by omitting the included LSX motor mount stands.
  • Factory low-mounted LS A/C compressor requires relocation when using this tubular K-member. An A/C relocation kit is recommended (see www.kwikperf.com).

Built and track-tested for real-world performance, the UMI 2403-B K-member delivers a reliable, high-strength front subframe upgrade that is equally at home on a daily driver or a dedicated performance build.

Good call with Clint on fitment

THANK YOU

Very good

I had placed my order and then had been checking the confirmation email site for updates on processing and when it was shipped. It had been over a week with no updates noted just that the order was received. I emailed customer service to see if my order had shipped yet and was told they would check with the warehouse to check the status. They responded quickly to let me know what date it was shipped and provided tracking information. I appreciated the quick response and follow up by your customer service representative. Perhaps keeping the "progress of order" page updated to real time more often would be beneficial.

So far so good. Hurry up and ship these to me!
