It is generally considered on the FJ Owners Forum that
the bike benefits from an increase in rear ride height.
The older of my two FJ does seem a little low a the back -
something may have sagged over the years - it happens to us all. So I thought
I'd try it out. The costs are minimal and I'm always up for a bit of tinkering.
As with any bike with a linkage type rear suspension the
ride height can be adjusted by making new "dog bones" with a
different hole spacing. A shorter spacing give increased ride height and visa
versa. Advice from the Forum is that 5mm reduction in spacing gives a 25mm (1
inch) increase in ride height. The original dog bones are single flat pieces of
mild steel so replacements are easily made.

Part #15 are the dog bone linkages to be replaced. |
 |
I sourced a flat bar 35mm x 6mm x 1000m from Wickes hardware
store. |
 |
The bar is the same thickness as the originals and
slightly wider |
 |
It's important that the new linkages are exactly the same
length so I tack welded the plates together & marked them out for drilling |
 |
A step drill is the best way to get a clean 12mm hole |

Given a coat of paint |

FJ with original linkages (left) and new linkages
(right) - not a lot of difference. |
I'm not using the bike at this time of year but it felt ok
during a quick spin round the block. The roads are too wet & greasy for
heroics just now so I'll have to wait until spring to find out how it
works.
