User Experiences

“I’ve had my fair share of heater boxes in the past, and let me tell you, this Kenworth Stainless Steel Heater Box is a game-changer. Not only was it a perfect fit for my T800, but the fact that it doesn’t rust is fantastic. I’ve driven through some harsh conditions, and it’s held up great. No more wasting time and money on replacements for me. Highly recommended!”

“I was a bit hesitant at first because of the price, but I’m so glad I invested in this heater box. It’s super sturdy, and you can tell it’s made of quality material. Plus, the free shipping was a nice bonus. Installation was a breeze, and it came with everything I needed. For anyone on the fence, trust me, it’s worth every penny.”
