★ High-quality reproduction for the classic Ross steering box. Replacement of this seal eliminates oil leakage and contributes to precise, play-free steering.
Application
Suitable for Willys MB (1941-1945), Ford GPW (1941-1945), CJ-2A (1946-1949), CJ-3A (1949-1953) and CJ-3B (1953-1964) with Ross steering box and 7/8" sector shaft. Also applicable to early CJ-5 models (1955-1966) with four-cylinder engine.
Installation notes
The seal is fitted to the side cover of the steering box where the sector shaft exits. When replacing, clean the steering box, remove the old seal and carefully fit the new seal without damaging the lip. Check the sector shaft for grooves or wear — a damaged shaft can cause a new seal to leak immediately.
Compatibility
This seal fits all Ross steering boxes with 7/8" sector shaft. NOT suitable for M38/M38A1 (these have 15/16" sector shaft) or later CJ-5/CJ-6 with V6 engine (1" shaft). Always check the diameter of your sector shaft before ordering.
Historical context
The Ross Gear & Tool Company of Detroit supplied the steering boxes for virtually all military Willys MB and Ford GPW jeeps during WWII. These seals are critical sealing components that prevent oil leakage and extend the service life of the steering system.
