Please note we will only cut these on Thursdays in order to minimize fixture swapping in our machine. Please contact us if you have an urgent need for one.
These are made to order lower pulleys for the Innovator's West LSA and Camaro/CTS-V LT4 balancers. They are machined from 6061-T6 aluminum.
The pulleys are available in any size for either 8-rib, 10-rib, or 12-rib configuration up to an effective diameter of 10.5". These are made 100% in house. Anodizing is available for an extra fee (and may add significant time to delivery). Please choose your rib configuration from the drop down menu, and specify the size of the pulley in notes when placing your order. We can typically ship within one week of ordering (usually faster). Returns are not accepted on custom cut pulleys.
Due to a slight misalignment between LSA and LT4 as a result of the IW dimensioning, please make sure to note if you are ordering a 10 or 12 rib for the LT4 so we can adjust the offset to ensure rib alignment in the drive system. The regular 8-rib pulley is reversible (install one way for LSA, install the other way for LT4).
OEM LSA diameter is 199.93mm (7.87").
OEM LT4 diameter is 204.97mm (8.07").
