Classic Volkswagen Type 2's have an axle beam up front, and inside that beam are Torsion Leaves. They are also known as Torsion Leaf, Torsions, Torsion Springs, Torsion Slats, Torsion Bars, or the OEM part number for the link pin application is 211411033. There is an upper and a lower needed for each vehicle.
Each tube houses ten leaves, four wide and six small, three on top and three on the bottom. They form a hexagonal shape.
One thing to remember when dealing with suspension is AGE. Since the ball joint suspension was born in 1955 (Non Barndoor applications), these torsion leaves can be up to 68 years old (2023) and have lost spring tension, causing the vehicle to sag over time. So although you might have a stock condition suspension set up, it is a certainty that your Classic VW has lowered over time.
These torsions come from Volkswagen of Mexico and are NEW, not used. They are offered stock width.
