265/75/16 BFG A/T KO rubbing on stock 2004 dbl cab

I have the understanding that those are designed to provide 3" of lift. I'm not trying to lift my truck

 

OME 880's are probably what you want. Should be about 1" of lift unloaded, then add your bumper and winch. Otherwise I'm not sure of any other coils designed to handle the additional weight without lifting. I'm sure they're out there though. You could also call up Toytec and tell them what you want, they should be able to find something for you.

 

Okay thanks. If my garage is slightly level (which it probably isn't), the bumper and winch seemed to pull down the front about an inch. I'm for sure on getting 5100s, just thought i should replace the coils as well to kinda help support the weight. Unless, if that is completely unnecessary, I won't do it. I am just unsure...
