Sonnax Ford C6 servo apply levers are made from 6061-T6 aluminum forgings, which are less susceptible to distortion and cracking than the cast OE levers. These levers are excellent as replacements for hard-to-find, OE servo levers which are no longer in production. servo apply lever 36916E is a direct replacement for the OE E ratio 1.85 lever C6AZ-7330-D and will provide firmer, cleaner shifts when used with "R" ratio servo piston kit [K36528R] For greater band apply force with a given servo, servo apply lever [36916FF] features a special, non-stock FF ratio 2.82:1. Due to this aggressive lever ratio, does not recommend using this lever with H or R code servos. * Combine levers with different sized servos to correspond with specific application needs* Made from forged 6061-T6 aluminum* Replaces hard-to-find OE levers
