The Speedmaster PCE237.1006 is a Gilmer-style synchronous drive belt measuring 39.0 inches in length and 1.5 inches in width, carrying the 390L150Hsn specification. Gilmer belts feature a positive-tooth drive design that eliminates slippage, making them a popular choice for high-performance engine accessory and supercharger drive applications where precise, consistent power transfer is essential.
Sold as a belt only, this unit is ideal for builders sourcing a replacement or completing a custom drive system using compatible Gilmer pulleys. Verify your existing pulley tooth pitch and belt length requirements before ordering to ensure a proper fit with your specific setup.
