  • Want to dress-up your LS family Chevy engine and wondering what to do with those pesky coils in such a confined space? The die-cast aluminum LS Slant-Edge valve covers allow you to personalize and customize the appearance of your engine. In addition, Proform has designed an attractive way to lift your coils off your valve cover so you can see the Chevrolet emblem. A unique rail mounting system attaches to the threaded holes on the valve cover, and the individual coils attach to the rail so they can be mounted in multiple positions! Coil brackets and valve covers include necessary hardware, coil extension harnesses for altering engine location sold separately.

    Note: Stock spark plug wires are not long enough to work with this coil bracket. MSD's 13" spark plug wires, part no. 121-39849 are recommended. 13-15" wires are needed if making your own wires.

    JEGS Easy Kits are designed by JEGS professionals so you get all the parts you need.
