Your Corvette's radiator mounting isolator cushions are essential to protect your radiator from chassis vibration and dampen severe impacts that can damage your radiator's fragile core. From the factory, your C4 came equipped with rubber radiator isolator cushions that quickly lose their effectiveness from exposure to heat and underhood contaminates.
Now you can upgrade your C4 with a set of 1984-1989 Polyurethane Radiator Isolator Cushions! These cushions not only restore all of the benefits your original units provided, but their polyurethane construction also makes them less susceptible to the effects of extreme underhood temperatures and contaminates for an increased service life.
If you are replacing your Corvette's radiator, be sure to inspect your isolator cushions and take the opportunity to upgrade for peace of mind and years of dependable service.
