Anyone have any ideas or suggestions about how to insulate the floor of my TJ? I am getting a ton of heat up through it after I have driven around a little bit. I noticed there is a strip of insulation under the jeep , above the muffler, but I am wondering if anyone knows of something that might go under the carpet?
A small body lift could help. Idk for sure but it's a thought anyhow.
It doesn't and neither does the rhino lining. It sounds like the op currently has carpet. If so pull the carpet out and drive a few days without it. When you put the carpet back in it will be a huge improvement. I have heard bedrug has better insulation than factory but have no personal experience with it.
I wrapped my exhaust with heatwrap from the collector back to the rear axle and built a heat shield for my muffler. I also have my header wrapped, and since i run without carpet i put 3 heavy coats of bedliner on the interior of my tub and with my molded floor mats in I ca drive around all day in flip flops with no problems. Even in the summer with the hardtop on and no a/c its not bad.
Get a new shift boot that bolts to the floorboard. Also, I bought some light insulation from Lowe's. It came in a roll, metallic looking. it was very inexpensive. I put the insulation next to the floorboard under the carpet. No more heat issues for me.
Adding insulation, thicker carpet, etc., is fine but depending on how you use your Jeep, could become a problem if it gets wet. Aside from the eventual smell, it could cause rust problems. And, taking it out to dry it could become a PITA too.
