Thread: SLS to Coils

Why do you want to replace your airbags with coils?

I have seen several "coil conversion kits" but I can't seem to find a kit that doesn't include springs.

Thanks.

You just need the spring seats and bolts to fit them. You also need to tell the SLABS ECU it is now coils.

cheers

Ditto imatt's question. The SLS is great for leveling loads, towing and especially off road where you can raise the rear another 40mm - instant extra suspension lift

He might be sick of the maintenance.

I love my coils and have airbags (aftermarket) in the rear for towing my 21' Seafarer. It handles and rides very well, but if you want to know what its like just go for a drive in one of the many that have coils.

Cheers

Yep I don't think you can buy the conversion kit without the springs. I'm looking at doing the same, for reliability and just a general ride improvement.
As mentioned earlier you will have to take the landy to a dealer to turn off the sls at the ecu. Or for the time being just pull the fuse to the SLS until you get to a dealer. Only downside with that is you will have the light on the dash.

Does anybody know, if after a coil conversion, you can use the existing compressor, lines, and the button on the dash to pump up aftermarket airbags?
I'm guessing if the hose connection to the new airbags and the existing lines is the same then there shouldn't be a problem right?
Because the levelling sensors will continue to pump air until the sensor reads the correct height...
Maybe just a spacer on the sensor to suit your new lift?

You can get the seats without coils if you contact MR Automotive in Redcliffe QLD, as much as i dislike them.

I have had my SLS out for 2 years and still havent bothered to tell the ECU they arent there anymore. The light is on but doesnt bother me. I stripped all the comp sensors etc out of it at the same time and havent regretted it for a second. The bags are great for towing but hopeless for articulation.

This is possible but will require some fiddling around. There was a post here recently on this. Short story is yes but may as well replace the existing bags for the effort and an inferior result.
