Step-by-step guide to installing an Armordillo drop step on a Dodge RAM 2500 Crew Cab. Includes tools, common mistakes, and fitment tips.
Quick answer
Installing an Armordillo AR Drop Step on a Dodge RAM 2500 Crew Cab is a straightforward bolt-on job that requires basic hand tools and about 90 minutes. The key is to mount the step close to the rocker panel for a clean, factory-like appearance.
Why the Armordillo AR Drop Step fits the RAM 2500 Crew Cab well
The ARMORDILLO® AR Drop Step is designed specifically for 2010-2018 Dodge RAM 2500, 3500, 4500, and 5500 Crew Cab models. Its aggressive angular structure mounts close to the rocker panel, giving a tight, factory-refined look that suits lifted trucks without looking aftermarket.
The matte black finish hides dirt and scratches better than gloss options, which is practical for work trucks. The step is engineered to lower the entry point, making cab access easier for shorter drivers or when the truck is lifted.
Trade-offs to consider before installing
Because the drop step mounts close to the rocker panel, it may reduce ground clearance slightly compared to a flush-mounted step. This is rarely an issue on a 2500 Crew Cab, but if you frequently off-road over large rocks, you might want to check clearance before final tightening.
The step is not compatible with all aftermarket rocker panel guards or side skirts. Verify that your truck does not have any non-factory trim in the mounting area before you start.
Installation steps for the Armordillo AR Drop Step
- Gather tools and inspect the mounting area: You'll need a 13mm socket, a ratchet, a torque wrench, and a marker. Clean the rocker panel area where the bracket will sit. Remove any dirt or rust so the bracket sits flat. A common mistake is skipping the cleaning step, which can cause the bracket to sit unevenly and rattle later.
- Position the bracket and mark holes: Hold the bracket against the rocker panel in the desired location (typically just behind the cab door). Use a marker to indicate the bolt holes through the bracket slots. Double-check alignment with the cab door swing. If you mark the holes too far forward, the step may interfere with the door opening. Test the door swing before drilling.
- Drill pilot holes (if needed) and install the bracket: Most RAM 2500 Crew Cabs have pre-existing threaded holes in the frame. If yours does not, drill 1/8-inch pilot holes first. Attach the bracket using the supplied bolts and torque to 35 ft-lbs. Over-torquing can strip the frame threads. Use a torque wrench and do not exceed the spec.
- Attach the step to the bracket: Slide the drop step onto the bracket's mounting tabs. Align the step so it is level and sits close to the rocker panel. Tighten the step bolts to 20 ft-lbs. A gap between the step and rocker panel looks unfinished. Adjust the step before final tightening.
- Test clearance and final check: Open and close the cab door fully. Check that the step does not contact the door or any moving parts. Walk around the truck and verify the step is secure and visually aligned with the body line. If the step rubs the door, loosen the bracket bolts and shift it rearward slightly. Re-tighten and recheck.
