Idler Pulley - 10 or 12 Rib - Smooth - 70mm

Built for high-speed, high-load applications, this 70mm idler pulley is precision machined from 6061-T6 billet aluminum for strength, durability, and reliable belt engagement. A high-load, double-row bearing provides increased support and service life, while the black anodized finish adds a durable layer of protection against wear and corrosion.

All TooHighPsi 12 rib pulleys utilize a '+3, -1' rib arrangement compared to the stock LT4 8 rib drive (3 ribs are forward and 1 rib is back of the standard OE 8 rib), or '+1, -1' arrangement when compared to the THP 10 rib drive.

The pulley includes a dedicated spacer and mounting bolt for bolt-on installation.
