The Cognito Fender Trim Finishing Caps solve a common aesthetic and functional problem when removing factory splash guards on heavy-duty Silverado trucks. Because the OEM splash guards are integrated into the fender flare design, removing them typically leaves the flare ends open and unfinished. These finishing caps provide a clean, factory-style look and are essential for owners wanting to properly install Gatorback mudflaps.

Constructed for durability and a precise fit, these caps are trimmable, allowing you to gain necessary clearance for slightly larger than stock tire and wheel combinations. Installation is straightforward, requiring no drilling into the vehicle body, and can typically be completed in 15 minutes.

The Cognito Front Fender Liner Tie Back Kit is an essential upgrade for owners looking to fit larger tires and aggressive wheel offsets on late-model GM heavy-duty trucks. These brackets serve as a direct bolt-on replacement for the stock rear lower fender liner brackets. By pulling the lower rear portion of the front wheel well liner further back toward the cab, this kit creates the necessary clearance to prevent rubbing without sacrificing the professional look of the wheel well.

Constructed for durability and a factory-style finish, the brackets are powder-coated in semi-gloss black. For trucks with a 3-inch leveling kit, this modification allows for up to 35x12.5-inch tires on 9-inch wide wheels (-18mm to +18mm offset) or 10-inch wide wheels (0mm to +10mm offset). It also enables the use of 37x12.5-inch tires on 9-inch wide wheels with a +18mm offset.

• Replaces OE rear lower fender liner brackets to increase tire clearance
• Durable semi-gloss black powder-coated finish
• Supports up to 37-inch tires on select wheel/offset combinations
• Simple 30-minute DIY installation
• Compatible with factory mud guards (requires trimming)
• Includes all necessary installation hardware
• Made in the USA
• Manufacturer Part Number: 110-91193
