✅ Three quarter outer diameter keeps housing footprint tight
✅ Point eight inch thick body absorbs lateral thrust without twisting

- Hardened steel fights off gravel and mud that destroy thin raceways fast
- Precision ground surfaces cut heat buildup so components run cooler longer
- Standard sizing swaps easily across most American farm and work trucks
