Product Description

Installing spacers between the k-member and the chassis creates more clearance between the top of the engine and the underside of the hood. The increased clearance to the hood aids with some engine swaps, such as when putting a 5.4L Triton truck engine into an SN95 Mustang.

When installed on a Mustang that also has a front coil-over kit these spacers have no effect on ride height. The spacers move the k-member downwards from the chassis, towards the ground.

When installed with a stock k-member, and with the springs still in the stock location, the ride height will change. The chassis will move upwards by the thickness of the spacers, and the k-member will remain the same distance from the ground.

5.0 Mustang and Super Fords magazine used MM k-member spacers on their Fox 500 project car. With the MM spacers, the Shelby GT 500 supercharged 5.4L engine was lowered enough in their Fox Mustang that the hood modifications needed to clear the intake were much less radical than would otherwise have been required.

This 1/2" spacer kit includes four aluminum spacer plates to fit between the k-member and the chassis. Longer k-member attachment bolts are included. Reuses OEM nuts and nut-plates. Spacers are also available in 1/4" thickness.

A front-end alignment will be necessary.

5 Stars   nice quality easy install
By on 2/28/2017
I got these and was nervous having to install them because engine and k member was still in car, but as i started to do the install it was really easy, i worked on 1 side at a time, was able to just put car on stands and put jack under the center of the k member and drop all the mounts then just lower k member enough to slide the mounts in and bolt up, really was easy, i did have to lower my coil overs all the way down to reach the same level on the car, but no big deal, but if you want a slammed car you will not be able to have that anymore, over all it fixed my issue of my terminator swap k/b pulley from hitting my new 3 inch cowl hood, It did its job!!

Yes, I would recommend this item to a friend!
