I'm digging this new rear bumper from DV8. https://dv8offroad.com/collections/jeep-jl-rear-bumpers/products/wrangler-jl-rear-bumper-fs-15

The factory rear bumper is light, but if come off a ledge, the rear support brackets buckle the sheetmetal on the JL. So I picked up a fabricated steel bumper to match the front and it's great.
