SKF STK235-B Manual Transmission Bearing Kit

SKF STK235-B is a manual transmission bearing and seal overhaul kit for light-duty applications that need a precise rebuild of the transmission’s wear components. It is built around matched bearings, seals, and applicable gaskets to support a complete repair on select Chevrolet and GMC trucks and SUVs.

Key Features

  • Manual transmission bearing and seal overhaul kit for light-duty service
  • Includes high-quality bearings with matching cones and cups
  • Seals use SKF Bore-Tite coating for improved sealing performance
  • Form-fitting gaskets and silicone sealant are provided where applicable
  • Built to meet or exceed original equipment specifications
  • Part number: STK235-B

Detailed Description

SKF STK235-B is designed for manual transmission rebuilds where bearing wear, seal leakage, or gasket failure has affected shift quality and drivability. The kit focuses on the internal components most often replaced during overhaul, helping restore proper transmission operation in applications such as the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet S10, GMC Sonoma, Chevrolet Blazer, GMC Jimmy, Chevrolet K1500, GMC K1500, and related light-duty platforms. This part number, STK235-B, is also referenced for select Getrag 2nd and 3rd design transmissions with 1.180-inch countershaft bearing applications.

SKF manufactures the bearings, seals, and related components to OE-level standards for consistent fit and long service life. This part cross-references 20839-5007 and 79563 for the same application.

What It Helps Fix

  • Transmission noise from worn bearings
  • Gear engagement issues caused by internal wear
  • Fluid leaks from aged transmission seals
  • Service repeat repairs from incomplete overhaul parts
  • Seal and gasket deterioration in high-mileage manual transmissions

Installation Notes and Tips

Verify transmission design, bearing style, and countershaft bearing inside diameter before ordering. Fitment for STK235-B includes 1991-2007 Chevrolet and GMC manual transmission applications with specific Getrag 2nd and 3rd design notes, so matching the transmission code and bearing dimensions is essential. Clean all sealing surfaces thoroughly, inspect shafts and races for scoring, and replace worn components during reassembly to support proper bearing preload and sealing.

Quality Assurance

SKF states that these kits are manufactured to high quality standards and use components that meet or exceed original equipment specifications. The included seals feature SKF’s Bore-Tite coating, and the bearing sets use matched cones and cups for consistent assembly.
