Tri-5 Smooth Firewall and Recess

Smooth Firewall Kit

Installation Instructions

Anyone installing anything in a Tri-5 other than an inline six knows it’s a tight fit at best. We’ve taken the big hammer method out of the equation by creating a smooth firewall with a wider recess that works perfectly with our ExtReme chassis and LS engines. Those doing engine swaps using factory frames can also take advantage of the extra room this kit provides, opening the engine recess area to 3.5″ deep, the top of the opening is 3″ down from the top of the firewall, the inner width is 21.5″ and the outer width is 25.5″. This kit does require some fabrication and welding to install.
