51117417786 Front Grille | Bilateral Radiator Grille Set

The 51117417786 Front Grille utilizes injection-molded ABS with chromium-plated vertical slats, maintaining 0.6mm gap consistency across all 13 blades. Its UV-stabilized polymer base material withstands 150°F thermal cycling while retaining dimensional stability within ±0.3mm. The interlocking design features 8 corrosion-resistant mounting tabs that align with factory bumper receptacles.

Aerodynamically optimized contours reduce air turbulence by 22% compared to aftermarket alternatives. The dual-texture surface combines high-gloss chrome accents with matte black peripheral framing, matching original equipment visual characteristics. Pre-installed vibration dampeners eliminate harmonic resonance between 55-75mph.
