Bilstein B6 Performance Rear Shock Absorber — Swing Axle VW (1950-1968), Monotube (97-4006-0)
The street-performance rear shock for vintage VWs with the original swing axle rear suspension. Bilstein B6 Performance rear shock absorber for swing axle VW Beetle, Karmann Ghia, Bus, and Type 3. EMPI part #97-4006-0 (Bilstein 24-181488).
Vehicle Fitment
- VW Beetle (swing axle rear): 1950-1968 — Standard Beetle before IRS conversion; some early-1969 Standard Beetles also retained swing axle, so verify your specific car.
- VW Karmann Ghia (swing axle rear): 1956-1968.
- VW Bus / Transporter: 1950-1967 (swing axle rear).
- VW Type 3 (swing axle rear): 1962-1968.
- Will NOT fit: IRS rear ends (VW transitioned to IRS in 1969 on Beetle and Karmann Ghia — for 1968-1979 IRS Beetles order #97-4005-0 instead), or off-road builds with modified rear shock mounting.
Why Choose Bilstein?
Bilstein has been the OE shock supplier for serious driving cars — Porsche, BMW, Mercedes, Audi — for over six decades. The B6 series is their street-performance line, built around a monotube gas-pressure design that resists fade, doesn't foam under repeated cycling, and provides a more linear damping curve than twin-tube stock-replacement shocks. The swing axle rear is famously prone to oversteer with worn shocks; the B6 controls wheel motion much better for more predictable handling.

Frequently Asked Questions
- How do I know if I have swing axle or IRS? Look at the rear wheels. On swing axle cars, the rear axle tubes hinge at the transmission, and the wheels visibly tilt inward (positive camber) when the car is jacked up. On IRS cars, the rear suspension uses independent control arms with constant-velocity joints, and the wheels stay more upright. The transition was the 1969 model year for Beetle and Ghia; Bus stayed swing axle longer.
- Is this sold as a pair? No, single shock. Order two for a complete rear-axle replacement.
- Will B6 shocks help with swing axle oversteer? Indirectly, yes. Better-controlled wheel motion means the rear stays more predictable under cornering loads. They won't eliminate the swing axle's geometric tendency to tuck under, but they'll make the car much more consistent and less prone to surprise lift-off oversteer.
- How long do they last? Bilstein B6 shocks have a typical service life of 60,000-100,000 miles in street use.
- Do I need to replace front and rear at the same time? Strongly recommended. Mixing performance shocks at one end with worn stock shocks at the other creates handling imbalance. Pair these with the matching front B6 for your front suspension type (link pin or ball joint).
- Will these work on a swing axle Bus? Verify mounting and length before ordering. Bus swing axle rear shocks are different from Beetle swing axle shocks in some applications. Contact us if you're unsure.
