Rugged Liner WWC99 Rear Wheel Well Inner Liners
The Rugged Liner WWC99 rear wheel well inner liners protect your truck bed from road debris, rust, and impact damage. We engineered these liners with durable thermoplastic construction that withstands the harshest conditions while maintaining a precise factory fit.
Designed specifically for your truck’s rear wheel wells, the WWC99 liners install in minutes without drilling or permanent modifications. Our precision-molded design covers vulnerable sheet metal completely, creating a barrier against moisture, salt spray, and gravel that can lead to costly corrosion over time.
WWC99 specifications & protection details
Thermoplastic Construction & Impact Protection
The rugged liner wwc99 features advanced thermoplastic polymer engineering that absorbs impacts without cracking or splitting. Unlike thin rubber alternatives, our proprietary material maintains structural integrity through freeze-thaw cycles and direct sunlight exposure.
Heat and Cold Performance
We formulated the WWC99 to remain flexible in temperatures ranging from -40°F to 180°F. This temperature stability prevents the brittleness that causes cheaper liners to fracture during winter or warp during summer heat. The material’s chemical resistance also protects against gasoline, oil, and deicing salt that contacts wheel wells during normal driving.
Vehicle Fit & Installation Process
Each rugged liner wwc99 set is molded to match specific truck bed dimensions, ensuring coverage extends from the wheel well lip to the bed floor without gaps. We laser-scan OEM wheel well cavities to create installation templates that align with factory mounting points.
Mounting System
The no-drill installation uses existing body holes and clips that secure the liners without compromising your truck’s structure. You’ll complete installation in 20-30 minutes per side using basic hand tools—no special equipment required. The liners integrate seamlessly with bedliners like the WWC20HD heavy-duty model, creating a unified protective system.
Maintenance & Long-Term Durability
The rugged liner wwc99 requires minimal maintenance to deliver years of protection. Simply hose out accumulated dirt and road salt during routine truck washing—the smooth thermoplastic surface releases debris easily without scrubbing.
Cleaning Protocol
For stubborn grime, use a mild automotive soap and soft-bristle brush to preserve the textured finish. Avoid pressure washers above 1,500 PSI directly against liner edges, as excessive force may dislodge mounting clips. The UV-stabilized material resists fading and chalking, maintaining its appearance without protective coatings or treatments.

WWC99 Wheel Well Liner Questions
The WWC99 is designed for specific truck bed configurations, so fitment depends on your exact year, make, and model. Check our compatibility chart on this page or contact our technical support with your VIN number for confirmation.
We engineer each liner model using laser-scanned OEM wheel well dimensions, ensuring precise fitment when matched to the correct vehicle application. Our customer service team can verify compatibility before you order.
Yes, the WWC99 installs in 20-30 minutes per wheel well using basic hand tools. The no-drill design uses factory mounting points and included clips, making it a straightforward DIY project.
Our detailed instructions include vehicle-specific diagrams showing exact clip and fastener locations. Most customers complete installation in their driveway without special equipment or prior experience with automotive accessories.
The thermoplastic material in the rugged liner wwc99 maintains flexibility from -40°F to 180°F, preventing the cracking and warping common in extreme climates. We formulate the polymer specifically for temperature stability across all seasons.
This engineering ensures the liners won’t become brittle during winter cold snaps or soften during summer heat. The UV stabilization also protects against sun damage that causes cheaper materials to fade and degrade over time.
The WWC99 liners integrate seamlessly with spray-in bedliners, drop-in liners, and most tonneau cover systems. The low-profile design sits flush against wheel well edges without creating interference points.
We engineer the liners to work within OEM tolerances, so aftermarket accessories that fit your stock truck bed will continue functioning normally. The edges won’t block tie-down anchors or cargo management systems either.
Simply rinse the liners during regular truck washing to remove accumulated dirt and road salt. The smooth thermoplastic surface releases debris easily without requiring harsh chemicals or scrubbing.
For stubborn grime, use mild automotive soap and a soft brush. Avoid pressure washers above 1,500 PSI directly against mounting points. The material requires no protective coatings or treatments to maintain its appearance and performance.
The rugged liner wwc99 carries a limited lifetime warranty against manufacturing defects, reflecting the durability of our thermoplastic construction. With normal use and basic maintenance, expect years of reliable protection.
The UV-stabilized material resists environmental degradation that causes premature failure in lower-quality liners. Many customers report their Rugged Liner products outlasting the trucks they protect, maintaining both function and appearance long-term.
Yes, we sell replacement hardware kits containing all clips, fasteners, and mounting components used in WWC99 installation. Individual clips are also available through our customer service department.
We maintain parts inventory for every liner model we manufacture, ensuring you can service and maintain your investment years after purchase. This commitment to long-term support distinguishes our products from disposable alternatives.
