Thick Flange Water Neck - Chrome Plate - New
Offered at a great price for budget builds, our chrome steel thermostat housing features an extra thick flange for better sealing. Factory thermostat housings measure approx. .350" thick, which can lead to warpage and coolant leaks. Our super thick flange versions measure about .475" (nearly a half inch thick!!) to hold a perfectly flat surface for positive gasket sealing even under extreme conditions. These come complete with gasket and bolts (a $12 value when sold separately). The plating and overall quality on these is among the best we've ever seen. These use a 1 1/2" radiator hose, and fit all years and models of big blocks, including Hemis.
