Turbocharged racing applications with GM 350, 400, AT-500 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 350, 400, AT-500 or Powerglide application. Wear-resistant bronze lining Three times the melting point of babbit bushings Longer pump life Specs: Bushing Style: Precision Material: Bronze
