Front Wheel Well Liner Fastener Kit, Duramax | 2015-2025

Front Wheel Well Liner Fastener Kit, Duramax | 2015-2025

This kit has the 40 fasteners needed to refasten both front wheel well liners on 2015-2025 Chevrolet Silverado and GMC Sierra HD trucks with the 6.6L Duramax LML and L5P. The screws replace GM 11570637. The liners come out for many common service jobs, and the original screws often strip, rust or get lost along the way. This kit replaces all of them at once so both liners go back in tight, with no rattles or loose edges. It is hardware only and does not include the liners.

Key Features

• 40 Torx pan-head SEMS tapping screws with dog point
• Replaces GM 11570637 (Auveco 22070)
• M4.2-1.41 (#8) thread, 20 mm long, 17 mm washer
• Torx T-15 drive; black zinc-plated steel
• 40 required per truck; one kit does both front liners

Benefits

A wheel well liner held in with missing or stripped screws flaps, rattles and lets road spray, salt and debris into the engine bay. With a full set of fresh fasteners on hand, a job doesn't end with a liner held in by whatever was left over. Replace if worn or damaged.
