The THORparts front bumper will work with any brushguard you can find, as it bolts up just like the stock bumper. What may be an issue for some is the winch. Some brushguards have a crossbar right where the winch sits. So depending on your particular guard and particular winch...you may have to do some tweeking. I've sold a bunch of em, and only once did I run into this issue. The THORparts bumper is thicker steel than the stock one...so any guard you use will stick out further from the truck approx. 1/8" (assuming it mounts in the typical sandwhich fashion between the D-rings and the bumper).
The only sensor I have ever found (in numerous bumper installations), is a small one on the vertical brace in front of the radiator. I believe its an outdoor air temp sensor. I have my winch control box mounted very close to it. I'm not aware of any "airbag link" or "impact fuse" that is attached to the bumper itself...airbags are triggered by a brain located elsewhere.
$2600 for a brushguard???? Tell me you're joking.
