Direct Replacement for OEM Part Number BL1Z78632A23A. Are you sick of the worn-out original seat in your vehicle? Is it torn up, flattened, or do you lean to the left in your seat? Transform your ride back to it’s orignal glory starting with our Durofoam replacement cushion! Here at The Seat Shop, we didn’t set out to revolutionize the seat cushion. We just wanted a comfortable seat! When creating our Durofoam line, we took our time to match the factory specifications but INCREASED the density, creating a tougher, firmer, more durable foam cushion. Your seat cover will install directly to the new foam cushion using the same attachment methods as the OEM cushion. If you have heated seats, your OEM heater will easily transfer to the new Durofoam cushion. This model is manufactured with a reinforced backing underneath to help prevent the seat frame or spring assembly from cutting into the cushion. Stop putting up with aches, pains, and numb legs. Put Durofoam in your vehicle and enjoy the Durofoam Difference every time you sit in the driver seat.
