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. 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. * Special 2.82:1 ratio for more band apply force than any OE lever* Combine levers with different sized servos to correspond with specific application needs* Made from forged 6061-T6 aluminum* Firmer shift and better hold
