Bell Housing Bushing
Part No. 54253-01

View Instructions

The bell housing bushing on GM 180C, 4L30-E and AR25, AR35 transmissions becomes worn due to normal wear. Excessive clearance between the bell housing bushing and the converter hub will cause a front seal leak. Simply replacing the metal-clad seal will not fix the problem. Current aftermarket bushings do not fit the converter hub tightly enough and can have more clearance than a worn OE bushing. Sonnax bell housing bushing 54253-01 is designed to fit the converter hub properly and eliminate front seal leakage.

  • More tightly toleranced than aftermarket bushings
  • Prevents costly bell housing replacement
  • Bushing Style: Precision
  • Material: Steel-backed aluminum
  • Width: 0.560"
  • Shaft Dia.: 1.874"
  • Housing Bore: 2.003"
