Description

The 30.315in Long 6-Groove Serpentine Belt from Jones Racing Products is engineered for high-performance engine builds and serious modifications where OEM serpentine belts fall short. Designed for racers, enthusiasts, and builders pushing their engines beyond stock parameters, this belt delivers the precision and durability required in demanding applications. Whether you're running a stroker, supercharged, or naturally aspirated engine with upgraded accessories, this serpentine belt maintains consistent tension and reliable drive under the rigorous demands of track days, drag racing, or spirited street driving.

The six-groove design provides superior grip and load distribution across your alternator, water pump, power steering pump, and air conditioning compressor—critical for engine bays where accessory load increases due to upgraded components. Jones Racing Products manufactures this belt with premium elastomer compounds and reinforced construction, resisting heat degradation, slippage, and premature wear that plague standard belts in modified engines. The 30.315-inch length is precisely calculated to maintain proper tension across serpentine routing while accommodating the dimensional changes common in custom engine installations, short-block assemblies, and systems with relocated accessories.

This serpentine belt is ideal for engine builders, performance shops, and DIY mechanics upgrading cooling systems or accessory drives on modified vehicles. Installation requires correct pulley alignment and proper belt tension—verify your specific engine's serpentine routing and pulley configuration before purchase. The 6-groove profile is compatible with most modern small-block and mid-size engine platforms using six-groove serpentine systems; consult your engine documentation or reach out to confirm fitment on custom builds where alternator relocation, bracket modifications, or non-standard pulley sets may affect belt length requirements.
