WCS Autotecnica SU0818840 Front Door Gusset Assembly Set Left & Right

The WCS Autotecnica SU0818840 is a front door gusset assembly set including both the left (driver side) and right (passenger side) gussets. Door gussets serve as the structural seal between the frameless door window glass and the door panel, maintaining proper window alignment and preventing wind noise intrusion at highway speeds.

Over time, the rubber and composite materials in original door gussets stretch, crack, or tear — a known issue that leads to significant wind noise, especially at highway speeds. Replacing worn gussets with a quality set restores a tight, rattle-free seal and dramatically reduces cabin noise.

Key Features:

• Complete set includes both left (driver) and right (passenger) front door gusset assemblies
• Replaces OEM part numbers 61158SA010 (left) and 61158SA000 (right)
• Designed to restore proper window-to-door sealing on frameless window door designs
• Eliminates wind noise caused by stretched, torn, or degraded original gussets
• Direct-replacement design for a straightforward installation

Installation can be completed with basic hand tools including a 10mm socket, a Phillips screwdriver, and a flat-head screwdriver. Replacing both sides simultaneously ensures balanced sealing performance across both front doors.
