    Radiator Mounting Kit, Stainless Steel

    Mount your radiator correctly! Kit includes two 3/8"-24 x 2-1/4" mounting bolts, lock nuts, washers, springs, and a pair of rubber cushions approximately 1/8" thick.

    This radiator mounting kit is an OEM way of mounting the radiators on the early vehicles. The early vehicles had frames that were not of the same quality as today’s modern frames and also the roads were less than desirable and created a lot of body and frame flex and twist. This style kit eliminated damage to the radiator from the frame flex to a rigid mounted radiator. In today’s hot rod applications or OEM installations there are a couple of mounting options. The rubber pad goes between the frame and the radiator mounting flange. The spring can sit above the radiator mount tab or down below the lip of the frame. The bolt and applicable washer go through the mounting hole and spring and is retained by the included lock nut. Nut is tightened enough to put tension on the spring in the desired amount and thus letting the radiator absorb frame flex or twist by compression of the spring.
