Serpentine Belt 27.362in

The Serpentine Belt 27.362in from Jones Racing Products is a high-performance serpentine drive belt engineered for builders and enthusiasts running modified or racing engines that demand reliable accessory drive performance. Whether you're upgrading a street machine, competition vehicle, or custom build, this 5-rib belt delivers the grip and durability required to transfer consistent power to alternators, water pumps, and superchargers without slippage. A properly matched serpentine belt is critical to engine reliability—undersized or worn belts cause alternator dropout, coolant circulation loss, and accessory failure under load.

Manufactured to Jones Racing Products' exacting standards, the 5PK-695 HD features a five-rib profile that maximizes contact area and load distribution across your engine's pulley system. The "HD" designation indicates heavy-duty construction—this belt uses premium elastomer compounds and reinforced tensile cords to withstand the sustained torque, vibration, and thermal cycling common to modified powerplants. At 27.36 inches in circumference, this belt is precisely sized to match specific pulley configurations; incorrect length causes inadequate tension, slippage, or premature wear. The compact 0.13 lb weight reflects automotive-grade polymer engineering without sacrificing structural integrity or longevity.

This serpentine belt suits builders who have installed oversized pulleys, supercharger systems, or modified water pump drives and need exact-fit replacement belts that match their updated accessory stack. Correct belt length is non-negotiable—measure your existing belt or confirm pulley center-to-center distances before ordering. The 27.362in specification is critical; an oversized belt will slip under load, while undersized belts create excessive tension that damages bearings and shaft seals. Installation requires only a serpentine belt tool or careful leverage; most mechanical work can be completed in under 15 minutes. Check belt tension after 100 miles of driving and re-tension as needed to ensure long service life and optimal alternator output.
