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|
|The completed linkages|
|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.
