Sidecar setup

[apex1397]

Helping a friend set up a Cozy sidecar to his Triumph. Sidecar suspension  seems very stiff. 200 lbs.In the sidecar does not compress the shock at all. Any Cozy owners  out there.  Doesn't  seem right but I am not familiar with Cozy sidecars.

I'm tell you what I did with the Cozy torsion suspension.  Took it apart looked at it throned it away along with the wheel.  Bought a adjustable 450 lb.torision axel unit(smallest I could find) added removed from the splined shaft and extended the shaft with the axel attached to and extended it 2 in. And then put it back on the splined shaft(rubber not damaged) .And now it actes about like 200,250 lb. torsion axel.  Then I had move  the axel forward 2 in , so I could keep the sidecar axel between 12 & 16 in. forward of rear axel of bikes.  That's just some of the changes I've done. P.S. Lower side car to about 4in. off the ground.  And tubeless tire Rudyr

  I have never had a cosy Hack but all the stock sidecars I have had were stiff on the suspension.
 I have built using the torsion axle of the same weight and it worked well.
  The stiffest one I had was a Steib in the sixties but it was old when I got it.
 The softest one was one I built using a rear shock from a 650 Yamaha.  I changed for a shock I got from a sidecar company in Iowa.  That stopped the wallowing and it was rock solid up over 100 MPH.
 I have had 12 sidecar machines now.  Half of them I built from scratch.

This sidecar uses a coil over shock for suspension. SIdecar seems very light on right turns with the shock topped out.

I hacked a 2010 cast wheel Bonnie with a Cozy car.  I also thought the supplied shock was WAY too stiff.  When I removed that junk (along with the tire, tube, and wheel bearings which were also junk) it was next to impossible to compress in a shock tool.

It was replaced with a VW shock.  The part number escapes me but anything would be better than OEM from Cozy.
