These TransporterHaus Bay window drop spindles are the ultimate way to lower your bay window bus. 

If you have ever riden in a lowered bay window bus you will be shocked how good the ride quality is with these drop spindles.  Incomparable to a bay bus lowered with beam adjusters. 

Designed and Manufactured in Cornwall, UK.  

Machined not welded stub axle allowing fitment of the trailing arms from the under side giving a 3.5" drop and great ride quality.

No increase in track and will run with 14" wheels.

We've been testing balljoints from many manufacturers and finally chose one up to the job.  These ball joints are modified allowing them to be "locked".  This is in addition to the factory peening and friction fit.  

100% unwelded, not made from 2 sets of spindles.  No farm yard welding on a forged spindle.  

Includes 2 modified drum brake spindles and 4 modified trailing arms fitted with 4 new modified ball joints.

The ball joints we use are Heavy duty from the USA.

Track rods now fit from the underside to give extra chassis clearance.

£549 outright

£449 exchange

(we require a set of 4 ball joint bus trailing arms and a pair of bus spindles - any year)

Trade and distribution discounts available please enquire.

Additional parts you will require - 2 eccentric camber nuts (these are fitted onto your current upper ball joints), 1 adjustable track rod.  We can supply these parts if required.

Late bay running TransporterHaus drop spindles

How we make Transporterhaus 73-79 Late Bay ball joint drop bus spindles

We modify the ball joints and the trailing arms to include our own locking mechanism.  A spring ring expands into the trailing arm when the ball joint is pressed in locking it into place.  We have had over 15 tons on the fitted ball joints and have not been able to move them.

We modify the ball joints adding a locking mechanism for extra peace of mind.

After testing many different ball joints we came up with one up to the job.  Quality HD units which are made in the USA (not the Meyle one pictured above, which was used in testing).  If you are thinking of making a set of these for yourself don't use Meyle Ball joints!

Here's one of our custom trailing arms machined to accept our locking rings.

We machine the spindle to fit the ball joint from the opposite side.

The eccentric camber nut now fits on the bottom ball joint.  

Track Rod End fitting is reverse reamed to allow fitment of the track rod on the under side giving extra chassis clearance.
