Tracks USA tunnel and rails and new track

[Newfie Apex]

Here is what I found using this product....The rail extension is OK. Just OK.....Not a finished product. I used Muffin works ones before and the quality was so much better. The tunnel extension fitment was terrible..I had to fight with it to try and get it to fit right. Not even any holes in extension for grab bar. Metal thickness is also thinner than stock.. I guess I was expecting more after using Muffin works kit before .... I installed my 136"x15"x2" lug track last night..Loads of room between the track and the front cooler....
