2100kg tow bar parts needed to fit??

[whstatesman2000]

Hey guys,
does anyone know what other parts are needed apart from the towbar to fit one. strengething braces ect.. and ive been told that putting heavy duty bushes in the rear shocks to keep the self leveling suspension?
any one know what parts are needed and a price excluding the tow bar.
cheers

the self levelers are designed to take up to 2100kg since it was a factory fitted option on the towbar.

Not sure on the other stuff mate sorry
