Aftermarket multi leaf front springs added, but I would not use any spring that has been exposed to a fire or intense heat like those have seen.
Bilstien shocks with duals up front, but again the fronts are junk.
Stock rear springs with big lift blocks added along with a set of airbags, looks like maybe these didn't see as high of temps as the fronts.
Rear sway (anti roll) bar has been added, or it's one of the rare-ish stockers.
Personally I wouldn't use any of the stuff up front and would only consider any rear parts If it looks like there wasn't any high heat close to them, closely examine paint and rubber parts for evidence of excess heat.
Make sure the fire didn't warp the bumpers you like too much and be prepared to fully sand blast them down to clean metal before refinishing them. I would also be sure to use all new hardware.
