Keep the SLS as its a much nicer ride and makes the D2 self levelling when you add weight in the rear.

As above.

Keep the bags.

OK guys thanks for advice I have ordered 2 x new bags from rimmer brothers with clips to replace existing and will keep the good/old one as emergency spare.
Thanks again, Paul

Would also be wise to get a rebuild kit for the SLS compressor and a new air inlet filter and fit as well ...


The kits are available on ebay, come from the UK, and are dead easy to install.

Pump it up to off road height. Get a little spray bottle and mix dish washing liquid and mix it about 3 to 1. Spray it all over the bags, it will bubble where it's leaking.
I had a similar issue, the guy before me had been launching his boat and not washing the salt water off properly. Both bags had slight leaks, lots of tiny bubbles would bubble up when squirted.
Sometimes it the suspension would stay up overnight and sometimes it wouldn't, I just put it down to the way the bags were folding on themselves.
2 new bags and it was sorted but it did for them compressor from overworking it, just replaced it today!
