Best AMP Research PowerStep for 2006-09 Ram Mega Cab Guide

The 2006-2009 Dodge Ram Mega Cab sits noticeably higher than any 1500 or 2500 short-cab Ram before it, and that extra step-in height is the single most common complaint owners bring into our Tampa shop. An AMP Research PowerStep solves that problem in under two seconds: the running board drops on a sealed motor the moment a door cracks open, then folds flush against the rocker the moment it closes. This guide compares every AMP Research PowerStep kit that fits a 2006-2009 Ram Mega Cab (plus the matching Quad Cab board and the wider-stance extension brackets), with real prices, install notes, and the differences between the standard PowerStep and the newer PowerStep XL platform.

Why Add a PowerStep to a 2006-2009 Ram Mega Cab?

The Mega Cab was Dodge’s answer to the Ford F-250 SuperCrew — a heavy-duty Ram with a back seat the size of a Suburban’s. To package that interior on the existing chassis, Dodge stretched the cab rearward and lifted the body. The result is a daily-driver pickup with an unloaded rocker height of roughly 22 inches off the pavement, which is fine for an able-bodied adult but punishing on kids, older passengers, and anyone with a knee that does not love a hop.

AMP Research’s PowerStep is the original power running board: a tamper-resistant motor enclosed in an aluminum housing pivots a 6-inch-wide non-slip step down whenever any door is opened, and folds it back up the instant every door is closed. The step covers the area below the rocker so it is visually invisible when retracted, and the deployment is fast enough that a passenger reaching for the handle barely sees it drop.

For a 2006-2009 Ram Mega Cab the practical upgrades are three-fold:

• A real platform at roughly cab-floor height instead of a single-point grab handle
• No fixed running board hanging six inches below the rocker when the truck is loaded or off-road
• Synchronized LED courtesy lighting (PowerStep XL only) for nighttime curb-side use

How We Picked: Our AMP Research PowerStep Criteria

Every kit in this guide passes the same four checks before it earns a spot:

1. Direct fitment for the 2006-2009 Ram platform (DR/DH chassis). Generic step kits force the installer to drill, modify wiring, or fab brackets. Every product below is a vehicle-specific, no-drill mount.
2. OEM-style sealed motor with a published load rating. Standard PowerStep boards are rated for 300 lb per side; PowerStep XL kits are rated for 600 lb per side. Either number outclasses fixed nerf bars on a Ram of this weight class.
3. 5-year / 60,000-mile warranty in force. AMP Research backs every PowerStep against manufacturing defects under normal use, and the warranty pulls through when bought from an authorized US dealer like NLP Performance.
4. In stock and shipping from a US warehouse. Power running boards are a regulated electrical accessory, and grey-market kits often arrive without the correct OBD-II harness for the truck. We only list kits we can confirm shipping from US inventory.

Top 5 AMP Research PowerStep Picks for 2006-2009 Ram Mega Cab Owners

1. AMP Research 75118-01A PowerStep — 2006-2009 Ram Mega Cab (Top Pick)

This is the kit that started the PowerStep dynasty for the 2006-2009 Ram. The 75118-01A is engineered around the Mega Cab’s door positions, so the board centers correctly under each cutout instead of biasing front or rear like a generic universal step would. The aluminum housing carries the AMP Research black powder coat, the motor is sealed against road spray, and the trigger harness routes through the cab via the firewall grommet on the driver side. The plug-and-play OBD-II adapter ships in the box, so the only wiring you actually run by hand is the two trigger wires from the underside of the driver door sill.

2. AMP Research 75101-01A PowerStep — 2002-2008 Ram 1500 Quad Cab

If you have a 2006, 2007, or 2008 Ram 1500 Quad Cab (the rear-hinged half-door layout, not the Mega Cab’s full four-door body), the 75101-01A is the correct kit. The mounting brackets are spaced for the Quad Cab’s shorter rocker, and the board length is dialed in for the smaller passenger area. Wiring, motor, and warranty are identical to the Mega Cab kit. The biggest mistake we see Ram owners make is ordering the 75118 for a Quad Cab or vice versa — the boards will not fit the opposite chassis, and AMP does not split kits between cab configurations.

3. AMP Research 75130-01A PowerStep Extension Brackets — 2002-2013 Ram

This is the part Mega Cab owners running a leveling kit, 35-inch tires, or any 2-inch-plus lift need to buy. The 75130-01A is a bracket set, not a board, and it bolts between the factory PowerStep arms and the chassis to push the deployed step outward and reset the geometry of the deployed position. Without the extension brackets, a lifted truck can leave the board angled inward at full drop, defeating most of the height it just gained. At $169.99 it is the cheapest performance accessory on this list and the one most likely to save a torn pant leg.

4. AMP Research 77158-01A PowerStep XL — 2009-2012 Ram 1500 Crew Cab

If your trade-up is on the table for a fourth-gen (2009-2012) Ram 1500 Crew Cab, the 77158-01A is the PowerStep XL upgrade path. The XL platform brings a four-inch lower drop position, a 600-pound per-side load rating (double the standard PowerStep), synchronized LED courtesy lighting on each board, and a six-inch non-slip step tread. The motor and warranty are otherwise identical to the 75118 above. Listed here so Mega Cab owners considering a next-generation truck have a one-click reference point.

5. AMP Research 77168-01A PowerStep XL — 2010-2012 Ram Mega Cab

The 77168-01A is the Mega Cab’s direct XL upgrade. It is not a fit for the 2006-2009 truck — the 4th-gen Mega Cab uses different cab-mount points — but it represents the next chapter for owners who jumped from the 3rd-gen Mega Cab to the 4th-gen body. Same 600-pound load rating, LED lighting, and 4-inch lower drop as the Crew Cab XL above.

Standard PowerStep vs PowerStep XL: Which One Should You Buy?

For a 2006-2009 Mega Cab the question is academic — AMP only sells the standard PowerStep (75118-01A) for that chassis, no XL variant exists. But if you are weighing a future XL upgrade after a truck swap, here is how the two platforms compare in practice.

How Does the AMP Research PowerStep Install on a 2006-2009 Mega Cab?

The Mega Cab install is a three-to-four-hour job for a confident DIYer with a floor jack, basic hand tools, and a drill (used only for the OBD-II harness routing hole, which is in a hidden location). The general sequence:

1. Pre-flight. Disconnect the negative battery terminal. Park on level ground. Have a helper for the boards — each side weighs roughly 50 lb fully assembled.
2. Frame brackets. Five brackets per side bolt to existing factory holes in the frame and pinch weld. No drilling on the body or rails. On a Mega Cab the rear-most bracket lives above the rear leaf shackle.
3. Air tank relocation (2500 / 3500 only). Diesel trucks with the factory air system need the small compressor and tank moved rearward roughly two inches and up about an inch and a half using included shims. No air lines disconnect.
4. Board mount. Slide each running board into the bracket eyes, push the pivot pin through, and torque the retaining bolt.
5. Wiring. Run the two trigger wires up the driver-side firewall and into the cab. Connect the included plug-and-play OBD-II harness, route it under the dash, and reattach the OBD port. Diesel and gas Mega Cabs share the same harness.
6. First-power test. Reconnect the battery, open the driver door — both boards should drop within two seconds. Close all four doors and confirm both retract flush.

If the boards do not move on first power-up, the issue is almost always either a half-seated OBD-II adapter or a trigger wire grounded through the firewall grommet. Both are five-minute fixes.

PowerStep Buying Tips for 2006-2009 Ram Mega Cab Owners

Three small details that change a smooth install into a frustrating one:

• Confirm cab style before you click buy. AMP Research lists Mega Cab and Quad Cab as separate part numbers (75118 vs 75101) because the cab lengths are different. The boards do not interchange.
• Plan the air-tank relocation up front on a 2500 or 3500 diesel. The shims are in the box. The trick is doing the relocation before you start hanging brackets so the air lines have room.
• Order the extension brackets at the same time if you are running 33s, 35s, or a leveling kit. They ship in their own carton and pair with the base PowerStep at install time — no need to disassemble later.
• Keep the OBD-II adapter accessible. Some owners hide the adapter behind the lower dash trim. If you ever run a tuner or scan tool, you will need quick access to plug straight into the OBD port.
