Description

• Bearing and seal rebuild kit for 18 spline input 4-SP with 30 spline output.
• This is a “hybrid” rebuild kit. Includes 1 each 307/308 main bearings, tail shaft bushing, countershaft rollers/spacers/thrust washers, input rollers, snap rings and all appropriate gaskets & seals, including speedometer adapter O-ring and seal.
• Flat paper gaskets supplied in this kit are manufactured exclusively for Brewer’s Performance with a high performance matrix material, providing excellent flexibility, low flange pressure sealing, good bolt torque retention and reduced fluid wicking.
• This material does not require the use of additional sealants.
• Continuous temperature rated to 400 degrees Fahrenheit.
• Additional sealants can cause the gaskets to squirm while torqueing, thus resulting in a torn or damaged gasket.
• This kit works with bearing retainer 2538197 and extension/tail shaft housings 97623, 99128, 99539, and 99621.
• Please verify your transmission before ordering. Synchronizer stop rings sold separately.
