2007 Audi Q7 Front Seat Belt Tensioner Set L&R Used OEM 4L1857705A 4L1857706A

Genuine Audi OEM front three-point automatic seat belt assembly set. These safety components are precision-engineered to provide both daily comfort and critical protection. The integrated pyrotechnic tensioners are designed to instantly cinch the belt during a collision, securing the occupant in the optimal position for airbag deployment. Sourced from high-quality donor vehicles that have not been involved in airbag-deploying accidents, these belts are an ideal replacement for units with frayed webbing, locked retractors, or "slow-retract" fatigue. As authentic OEM parts, they feature the correct electrical connectors for the SRS (Supplemental Restraint System) and factory-matched interior trim colors.
