The only place to get the Nivomat in Australia is through Jeep at nearly $2000 each. Sachs are not supplying them to anyone else in Australia.
They have been unavailble in the US for the last few months.
The KYB SR2011 Excel G self leveling shocks are currently unavailable in Australia. I went to Rock Auto's website and they are available in the US, while I was on the web site I looked up the Sachs Nivomat 444-241 and they are also available and cheaper than the KYB.
KYB SR2011 AUD 323.88 each
Sachs Nivomat AUD 288.91 each
I ordered the Sachs delivered to Qld for AUD 708 for a pair. Paid with Paypal so if there are any issues I can get a refund easily.
