A dark rope of gear oil weeping onto the garage floor is the swing axle telling you its boot has split, and every mile after invites grit down the tube toward a scored gland nut and a leaking seal. This stock-style split boot seals the axle at the transaxle without pulling the hub, keeping the 356's oil where it belongs and the road where it doesn't.

• Split design installs over the swing-axle tube without removing the hub or drum
• Bagged as a complete kit with clamps and mounting hardware included
• Stock-style rubber matches the original swing-axle profile used on Type 1 chassis
• Interchanges with VW bulk number 111 598 021A (OE 111-598-021A)
• Sold each — order two to reseal both sides

Fitment: Fits the swing-axle Porsche 356, 356A, 356B, and 356C from 1950 through 1965, along with Type 1-based VW chassis of the same era. If you are unsure this fits your car, contact us with your year and model before ordering.
