Turbocharged racing applications with GM TH350, TH400, AT-540 and Powerglide transmissions get hot enough during staging that the common babbit pump bushings melt and disintegrate. This bronze bushing has a melting point three times greater than babbit bushings and will withstand the extreme peak temperatures seen in high-powered, turbocharged racing applications. Sonnax pump bushing 34234B-01 is a direct replacement that can be used to service any TH350, TH400, AT-540 or Powerglide application.

• Wear-resistant bronze lining
• Three times the melting point of babbitt bushings
• Longer pump life
