This product line is designed to meet the demands of performance-oriented vehicles, providing a balance between durability and enhanced stopping power. The silver zinc coating on the rotor hat offers additional protection against corrosion, making it suitable for various driving conditions.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is specifically designed for Mercedes-Benz SUVs such as the GL350, GL450, GLE400, GLS350d, and GLS450. The vented rotor construction allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps to evacuate gases, dust, and water from the braking surface, improving pad bite and reducing brake fade. The rotor’s nominal thickness of 32 mm ensures structural integrity, while the discard thickness of 29.4 mm indicates when replacement is necessary for safety. The zinc silver hat finish and rust resistant coating protect against corrosion, extending the rotor’s service life.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during heavy or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003cli\u003eMinimizes rotor warping caused by excessive heat\u003c\/li\u003e\n\u003cli\u003eEnhances pad bite and braking responsiveness\u003c\/li\u003e\n\u003cli\u003ePrevents rust and corrosion on rotor surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is compatible with your specific Mercedes-Benz model (GL350, GL450, GLE400, GLS350d, GLS450) before installation. Verify the bolt hole pattern (5 holes, 112 mm bolt circle diameter) and center hole diameter (67 mm) match your vehicle’s hub. Clean the rotor surface and hub mounting area to remove any debris or rust before mounting. Use proper torque specifications for lug nuts to avoid rotor damage or uneven wear.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures this rotor to meet OEM specifications for fit and function. The rust resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the rotor’s design and materials align with industry standards for replacement brake rotors on Mercedes-Benz vehicles.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":51795656081589,"sku":"HBHR-631-63146L","price":135.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_63163146L_Fro.jpg?v=1774641640","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-631-63146l-disc-brake-rotor-front-left","provider":"PartCatalog","version":"1.0","type":"link"}
