I thought Id share after much research:
For 0-50mm Lifts:
Koni Heavy Tracks 82-2297 in the rear
Koni Heavy Tracks 82-5020 in the front
These are twin tube, adjustable shocks. Initially meant for the HJ60, but they work good straight out from the box for the BJFJ40.
The Koni H.T. RAID versions are available too but with different mountings, so unless you do some custom job for them to work, you cant use them. parts are 90-5441 and 90-5462.
God Bless!
