Description
A failing tailshaft seal is a silent performance killer—allowing transmission fluid to leak onto your clutch, driveline, and chassis while you’re focused on the track. This OEM-quality Allstar seal restores the critical barrier between your transmission housing and tailshaft, preventing contamination and fluid loss that compromise both performance and reliability. Whether you’re running a TH350, Powerglide, or Bert/Brinn setup, this bolt-on replacement gets you back to baseline protection without downtime.
