Volkswagen Spindles 101

Accurate spindle information for Classic Volkswagens is shockingly hard to find in one place. Different model. Different year. Different bearing size. Different drop options. Different gotchas. By the time you've sorted through ten forum threads and two parts catalogs, you're more confused than when you started — and you still don't know which spindle actually fits your build.

We built this guide to fix that. The PROs at Airkewld have spent years working on every variant of these front ends, and what follows is the cleanest, most usable spindle reference we know how to put together — by model, by year, and by performance need.

If you're restoring a Beetle, lowering a Ghia, lifting a Thing, or trying to figure out what someone else already did to your Bus, start here.

Models Covered

• Type 1 – Beetle, Bug, Fusca
• Type 14 – Karmann Ghia
• Type 181 – Thing, Safari
• Type 2 – Split Window Bus, Kombi, Samba
• Type 3 – Squareback, Notchback, Fastback
• Type 34 – Razor Ghia

Type 1 & Type 14 (1949–1965): Link Pin Front Ends

Stock Spindles

These early cars use a two-piece king pin / link pin front end. The spindle (steering knuckle) rotates on a pressed king pin inside a carrier (yoke). The carrier also houses the steering stops and link pin bushings, letting the control arms cycle smoothly through their travel.

Spec	Measurement
Inner OD	24.90mm
Outer OD	19.80mm
Other components	Steel thrust washer, fiber wafer shim, centering cap

Important: Factory spindles in this era were forged — strong and durable. That matters when you start comparing aftermarket options.

Drop Spindles for Link Pin (Type 1 & 14)

All aftermarket drop spindles for this front end lower the car 2.5" (63.5mm). They differ in how they're built — and that difference shows up in how the car drives, lasts, and stays safe.

Cast Iron Drop Spindles

• The most affordable option; typically imported from China
• Brands include AC Industries, CB Performance, and EMPI
• Most use chromoly spindle shafts (some use cast shafts — not recommended)
• Add roughly 10mm (⅜") to overall track width
• Available in:
  • Drum brake (compatible with Airkewld disc brakes)
  • Disc brake — Ghia-style calipers
  • Disc brake — Wide 5 (5x205mm) with Escort-style calipers

A note on the disc-brake versions: most of these spindles were originally designed around 1966-and-later factory Karmann Ghia calipers. When CB Performance built them, they swapped to a 1969-and-later Beetle/Ghia shaft using 28.90mm inner bearings, 17.40mm outer bearings, and the 111405641B seal. Worth knowing before you order parts.

Forged Drop Spindles

• The strongest option, and what we recommend whenever the budget allows
• Currently only available through EMPI (originals from Century Distributors and Airkewld are no longer in production)
• No increase in track width
• Available in drum, Ghia-style disc, and EMPI Wilwood 4-piston disc
• Made in China

Welded Drop Spindles

• Custom-fabricated, drop height to spec
• TIG weld is strongly preferred over MIG
• Quality varies enormously depending on the fabricator
• Fine for experienced DIY builders with the right equipment — not something we'd recommend for a casual build

Type 1 & Type 14 (1966–1968): Ball Joint Front Ends

Stock Spindles

Factory forged. Specs:

Spec	Measurement
Inner bearing	26.90mm
Outer bearing	17.40mm
Seal	131405641A

Drop Spindles

These require bearing, seal, and tie rod end updates to 1969+ spec — so don't try to bolt them in with your existing hardware. Airkewld offers complete plug-and-play kits so you don't have to chase mismatched parts across three suppliers.

Compatibility (after 1969+ update):

Spec	Measurement
Inner bearing	28.90mm
Outer bearing	17.40mm
Seal	111405641B

Available in drum, Ghia disc, and Wide 5 disc (Escort-style caliper). Construction options — cast, forged, welded — are identical to the earlier link-pin section above.

Type 1 & Type 14 (1969–1977) + Mexican Beetles (1978–2004)

Stock Spindles

Factory forged.

Spec	Measurement
Inner bearing	28.90mm
Outer bearing	17.40mm
Seal	111405641B

Drop Spindles

Same construction and compatibility notes as the section above. Most drop spindles for this era assume Ghia-style calipers, or in Wide 5 setups, Escort-style calipers. Match your caliper before you commit to a spindle.

Type 181 (VW Thing / Safari)

The Type 181 is its own animal. Spindles for the Thing are:

• Forged from the factory
• Built with a 3.5" (89mm) lift baked in
• Only compatible with Type 181 trailing arms, ball joints, and eccentrics

If you're working on a Thing, do not assume Beetle or Ghia parts will cross over. They won't.

Type 2 (1955–1967): Split Window Bus

The Bus front end is the most complex assembly in the Classic VW lineup. A complete spindle setup includes the spindle itself, king pins, link pins, seals, bearings, stops, and races. Airkewld offers a stock spindle rebuild service for owners who want it done right without the parts hunt.

Year-Specific Stock Specs

1955–1963: Stepped spindle shaft

Spec	Measurement
Inner bearing OD	29.90mm
Outer bearing OD	24.90mm

1964–1967: Tapered shaft

Spec	Measurement
Inner bearing OD	31.65mm
Outer bearing OD	18.93mm

1968–1975 Brazilian Split Bus uses the same specs as the late German Bus.

Heads up for 2025: as of right now, no new reproduction Bus spindles are being made. Select components are sometimes available through BBT or Wolfsburg West, but supply is unpredictable.

Dropped or Flipped Spindles

Flipping the spindle gets you about 3.5" (89mm) of drop. To do it right, you'll need:

• Tie rod relocation
• Type 2 Bay Window tie rod ends (1968–1979)
• Reinforced machining for safety — non-negotiable

Welded Spindles

• Available from select builders
• Drop height customizable from 1" to 5"
• Quality is entirely dependent on the fabricator. Do your homework before handing over your front end.

Type 3 (Squareback, Notchback, Fastback, Razor Ghia)

Stock Spindles

Two variants exist:

• 1963–1968
• 1969–1973 (different bearings and tie rod specs from the earlier run)

Drop Spindles

Drop spindles for the Type 3 are rare and effectively discontinued. The only ones ever developed were built by berT3 in Belgium, and there's no current production. If you're chasing a lowered Type 3 stance, plan accordingly.

Not Sure What You Have — or What You Need?

Spindle compatibility is one of the easiest places to make an expensive mistake on a Classic VW. Wrong bearing size, wrong caliper match, wrong era hardware on the wrong year car — every one of those mistakes ends with parts on a shelf instead of under your fender.

If you're not 100% sure what spindle is on your car, what's compatible with the brakes you want to run, or which drop option fits your build, call us before you order. We'll talk it through with you — no pressure, no upsell, just the right answer for your car.

Start with the Ultimate Plan if you're planning a full build, shop by type if you already know what you need, or browse our catalogs for tailored builds.

The right spindle is the foundation of a great-driving Classic VW. Get it right the first time.
