Sonnax 34006-SPB Heavy-Duty Transmission Bushing Kit with Integrated Bearing

Description

The SON-34006-SPB kit was designed to address the issues of case bushing walkout and thrust washer wear that are common in the GM TH400, 4L80-E and 4L85-E units.   The Sonnax heavy duty case bushing kit 34006-SPB combines the tried-and-true no-walk case bushing with a high-quality thrust bearing that replaces the OE thrust washer and selective spacer.  This upgrade provides maximum durability to the rear area of these transmissions. Selective shims are included for setting and adjusting rear end play.
