WeatherTech ImpactLiner Truck Bed Liner

2019–2025 Ram 2500/3500 6.7L Diesel & 6.4L 392

Part #: 36707IM

Overview

The WeatherTech ImpactLiner is a premium, heavy-duty truck bed liner designed to protect your Ram 2500 or 3500 truck bed from everyday wear and tear. Engineered for models equipped with the 6.7L Diesel or 6.4L 392 engines from 2019 through 2025, this liner offers superior durability against dings, dents, scratches, and cargo shifting. Whether you use your truck for work, hauling heavy tools, lumber, or recreational gear, the ImpactLiner provides a reliable barrier that preserves the integrity and appearance of your truck bed.

Unlike traditional spray-in liners, the ImpactLiner is injection-molded from the same material as WeatherTech’s FloorLiner HP, delivering a tough, custom-fit solution that installs easily without professional help. It can also be installed over existing spray-in liners for enhanced protection, making it a versatile upgrade for any truck owner looking to extend the life of their bed.

Key Features

The WeatherTech ImpactLiner combines innovative design and durable materials to offer unmatched protection and convenience:

• Custom laser-measured fit for 2019–2025 Ram 2500 and 3500 models with 6.7L Diesel or 6.4L 392 engines
• Injection-molded from high-quality, impact-resistant material for long-lasting durability
• Patent-pending raised impact rings on the underside disperse force from heavy blows to protect the truck bed
• Elevated design allows air circulation beneath the liner to prevent moisture buildup and corrosion
• Textured ribbing on the top surface enhances cargo grip, reducing shifting during transport
• Raised walls on the sides and tailgate area contain spills and debris for easier cleanup
• Scratch-resistant surface maintains a like-new appearance over time
• Can be installed directly over spray-in liners for an additional layer of protection
• Ships ready to install with no professional tools or adhesives required
• Made in the USA with American raw materials and craftsmanship

Construction & Design

The ImpactLiner is crafted from a proprietary injection-molded thermoplastic material, the same used in WeatherTech’s acclaimed FloorLiner HP series. This material is engineered to withstand harsh impacts, resist scratches, and endure exposure to the elements without cracking or fading. The liner’s precise laser-measured contours ensure a snug fit that hugs every curve and corner of your Ram truck bed, providing comprehensive coverage and protection.

The underside features patent-pending raised impact rings that absorb and distribute the force of heavy cargo or accidental impacts, reducing damage to the truck bed itself. Additionally, these rings create a slight air gap that promotes ventilation and moisture escape, helping to prevent rust and corrosion over time. The top surface’s textured ribbing improves cargo stability, while the raised perimeter walls help contain spills and debris, making maintenance easier and protecting your investment.

Installation & Fitment

Installation of the WeatherTech ImpactLiner is straightforward and requires no special tools or adhesives. The liner ships directly to your door, custom-fit for your specific Ram 2500 or 3500 model year and engine configuration. Simply place the liner into your truck bed, where it will securely fit without shifting or sliding. If your truck bed already has a spray-in liner, the ImpactLiner can be installed over it to provide an extra layer of protection without any modifications.

This user-friendly installation process saves time and money compared to spray-in liners that require professional application and curing time. The ImpactLiner is designed for easy removal and cleaning, allowing you to maintain your truck bed’s appearance and functionality with minimal effort.
