AMP Research 20-03752-85 PowerStep Replacement Step Board Assembly 85in Single

Vehicle Fitment

• 2022-2025 Toyota Tundra - CrewMax Cab and Double Cab (Gas and Hybrid) - via parent kit 76338-01A
• Additional 2011-2025 Chevrolet, GMC, and Ford applications that use the AMP Research PowerStep with an 85-inch step board - verify your specific parent kit number before ordering

Fitment Notes

• This is a replacement step board assembly for AMP Research PowerStep electric running boards already installed on the vehicle - it is NOT a complete running board kit
• Sold individually - this listing covers a single replacement board for one side of the vehicle. Two assemblies are required to replace both driver-side and passenger-side boards
• On Toyota Tundra Double Cab applications, the boards must be trimmed to fit the shorter cab length - this is a requirement carried over from the parent kit 76338-01A installation
• The 85-inch board profile is the designated replacement for kit 76338-01A and is also shared across other PowerStep kits on longer-cab Chevrolet, GMC, and Ford configurations - confirm the board length used in the specific kit installed on your vehicle before ordering
• Hardware (screws, bolts, and fasteners) is NOT included - only the board and end cap pair are provided. Source hardware from the original installation kit or contact AMP Research directly
• Verify the exact AMP Research PowerStep kit number installed on your vehicle before ordering - contact AMP Research / RealTruck support at 1-888-983-2204 if unsure
• This product is non-returnable and non-refundable unless the part arrives defective - all sales are final

Features

• Direct-fit replacement step board assembly engineered to restore full function and appearance to AMP Research PowerStep electric running boards on covered Toyota Tundra and other applications using the 85-inch board profile
• 85-inch board length sized for CrewMax cab configurations and adapted (with trimming) for Double Cab applications, spanning the full length needed to serve both front and rear door entry points when deployed
• Constructed from aircraft-quality die-cast aluminum with an anodized black finish and military-grade PTFE coating - the same corrosion-resistant, abrasion-resistant construction as the original board
• Textured, non-slip 6-inch wide step surface maintains the same traction profile as the factory board in all weather conditions, including snow, ice, mud, and rain
• End cap pair included - provides a finished appearance at both ends of the board after installation
• Mounts directly to the existing AMP Research PowerStep linkage assembly on covered kits - no bracket or motor modifications required

Product Description

The AMP Research 20-03752-85 is the replacement 85-inch step board assembly for AMP Research PowerStep electric running boards installed on the 2022-2025 Toyota Tundra (CrewMax and Double Cab, Gas and Hybrid) via parent kit 76338-01A, as well as other Chevrolet, GMC, and Ford PowerStep applications that use the 85-inch board length. When an existing PowerStep board is damaged by impact, cracked from trail abuse, or surface-degraded beyond repair, this replacement assembly allows the board to be swapped without replacing the entire running board system.

The 85-inch board is the appropriate length for the Toyota Tundra CrewMax cab configuration, which requires full-length coverage for both front and rear passenger entry points. On Tundra Double Cab models, the board must be trimmed to the shorter cab length prior to installation - this is a standing requirement of the parent kit 76338-01A that applies equally when replacing the board on an existing installation. The replacement board is built from the same aircraft-quality die-cast aluminum as the original, with an anodized black finish and military-grade PTFE coating that resists corrosion and abrasion. The 6-inch wide, textured non-slip surface preserves the same traction characteristics as the factory board across all weather conditions. A matching end cap pair is included to maintain a finished appearance at both ends after installation. Mounting hardware is not included and must be sourced separately.

This assembly is sold individually and covers one side of the vehicle only - two assemblies are required to replace both sides. Because the 85-inch board length is shared across multiple PowerStep kits beyond just the Tundra application, it is essential to confirm the specific kit number and verify the 85-inch board length is correct before ordering. Contact AMP Research support at 1-888-983-2204 if the kit number is unknown. This is a final-sale replacement part - all purchases are non-returnable and non-refundable unless the assembly arrives with a confirmed manufacturing defect.
