FEATURES

Customer requests have indicated a need to supply a slip yoke eliminator (SYE) kit that utilizes the stock GM speed sensor. The most common application for this kit is the instance in which the entire drivetrain (engine, transmission, and transfer case) is being removed from a 4.3L equipped S-10 truck or Blazer and being transplanted into something else. In any instance where a GM speed pulse is needed, this kit fills the bill.

The new Shorty SYE kit features and all-new, 32 spline mainshaft and heat treated (T6) aluminum bearing housing. The kit measures 9" shorter than stock. This overall reduction in transfer case length equates in a longer rear driveshaft and improved driveline angles. The big 32 spline output shaft accommodates end yokes from 1310 to the 1 ton 1410 series.

Installation is easy and no special tools are required aside from a good pair of flat-head snap ring pliers (Sears). The transfer case can remain in the vehicle during the installation of the SYE however it is recommended that the unit be removed prior to the install.
