The stock 7.3 thermostat housings are notorious for leaking coolant. They are made from a thin press formed sheet metal that rusts, pits, and gets deformed by the bolts. To fix the issue we have machined a new piece from 6061 aluminum. This lets us build in a nice thick flange that will not flex or bend and also is much less susceptible to corrosion than steel.
Features:
-Machined from 6061 billet for maximum strength
-Greater corrosion resistance as well as great looks
-Thicker O-ring for even better seal
-New stainless bolts and washers for an excellent finished look
-Made in USA
-For 99-03 Only
Kit Includes:
-Billet Thermostat Housing
-O-Ring
-Stainless Fasteners (3)
