The INA FB5K402 is a serpentine accessory drive belt engineered to OEM specifications for reliable front-end accessory drive (FEAD) system performance. Manufactured by INA — a Schaeffler Group brand and trusted OEM supplier — this belt delivers consistent power transfer to engine accessories such as the alternator, power steering pump, air conditioning compressor, and water pump.

Key Features:

• OEM-quality construction for precise fit and long service life
• 5-rib (poly-V) profile designed for smooth, low-vibration power transmission
• Heat- and wear-resistant compound withstands high underhood temperatures and continuous flex stress
• Crack- and slip-resistant ribbed surface maintains positive engagement with pulleys

As a direct OEM-equivalent replacement, the INA FB5K402 serpentine belt restores proper accessory drive function and helps prevent accessory failure caused by a worn, glazed, or cracked drive belt. For best results, inspect the belt tensioner and idler pulleys at the time of belt replacement.
