I decided to go with the AMP XL Power Assist Steps for the HD ZR2.

These steps give you and additional 3 inches of drop utilizing a tube running along the rocker panel. The step folds up cleanly into the base of the tube for a nice clean look. I like that the finish matches the Bison bumpers really well.

They were the same basic install process as the 1500, but more hardware due to tube. The hardware is easy to install but helps to have another set of hands to hold one end in place. The electrical requires pulling two harnesses from the BCM and splicing two wires. It is tedious and a little hard to get to under the steering wheel fuse block panel.

Took about 1.5 hours for hardware install and 2.5 to 3 to run wires and make the splices/ connections.

I like how they look and give the appearance of rock sliders and eliminate some of the visible frame and skid plates visible on the Bison.

They are about 12.5 inches above ground and leave about 17 inches stepping into truck. I'm thinking of going to 37 inch tires, so the additional drop will be better.

For reference, the 1500 ZR2 is about 12 inches from ground and 14 inches stepping into truck. Definitely easier to slide into 1500.

They cost about $2,500 delivered. So instead of saving money on the standard AMPs, I ended up spending more than the cost of factory steps, so not any advantage for saving $.

The ordering process was a CF. There wasn't much stock, so I ended up ordering from NAPA online. The order was fulfilled by Auto Accessories Garage Newport Minnesota. That turned out to be a disaster.

NAPA website listed the wrong parts for this truck, so they shipped ones for a 2020 and electrical and hardware is not the same. If that wasn't bad enough, they shipped two boxes of the rail tube and no box with hardware or electronics. One of the boxes had been previously opened and inside it had different parts than the other box even though they had same part number. There is a big green sticker on boxes that states they are a set and not to separate box 1 of 2 and 2 of 2.

Customer service guy was nice and acknowledged it was their fault. Had to wait 2 days for appoval to return and they couldn't guarantee they had the right parts, so asked for refund. I finally got shipping labels and had to repack and haul them to UPS. 10 days later, I'm still waiting for refund.

Meanwhile, I called 4 Wheel Parts and they found me a set and had them two me in two days.
None of them have yet...... LOL! Back at the farm we've got proper quonsets and shops that handle man gear. This little turd garage is just for sxs and motorcycles and ammo.
