Seal Rear Tailhousing

The Jerico seal rear tailhousing (SKU JER0065) is a critical maintenance component designed for Jerico dirt transmission systems used in high-performance off-road and drag racing applications. This seal assembly prevents fluid leakage at the rear tailshaft housing interface, protecting transmission fluid integrity during extreme driving conditions. Whether you're rebuilding a competition transmission or performing routine maintenance on your off-road rig, this OEM-specification seal ensures reliable operation and extends transmission lifespan.

Engineered specifically for Jerico transmission housings, this seal rear tailhousing assembly fits the precise tolerances of the tailshaft opening, creating a hydraulic barrier that withstands gear oil pressure and mechanical vibration. The compact design—measuring 4.75 x 0.65 x 6.2 inches and weighing just 0.1 lbs—allows for straightforward installation during transmission assembly or service intervals. The seal material and design characteristics are optimized to resist degradation from synthetic and mineral-based transmission fluids commonly used in motorsports applications, maintaining effectiveness across extended service periods and temperature fluctuations inherent to racing and off-road driving.

This component is essential for builders and mechanics performing Jerico transmission rebuilds, particularly those working on dirt track cars, drag racing platforms, and off-road competition vehicles. Proper sealing at the tailhousing prevents fluid contamination from external dirt and moisture while stopping oil loss that compromises gear lubrication and cooling. Installation requires basic mechanical knowledge and fits as a direct replacement for OEM Jerico assemblies, making it ideal for routine maintenance schedules or full transmission overhauls where seal degradation has occurred.
