Thread: disco 2 centre diff lock & air springs

some models do not have the center lock fitted someone will be able too help you there I think around 2002 models, I have the air bags fitted to mine and I have owned it for nearly 12 years.

As for the air bags keep them It is handy for keeping it level no matter the load in the rear, the only modification have done is fitted one way flow
restrictors, this was because going down steep banks the back end would sit higher which would make the computer deflate the air bags.

Which when going back up any banks with the back end lower a bit harder, fitting the restrictors fixed this but they allow normal air flow rates when adding more air to the suspension but slow the air flow rate when deflating the bags.

Did you put the restrictors at the air lines(4mm) to the airbags,maybe a photo please would help
I have the very same problem,the strange thing is that when i reach flat ground,it doesn't level,maybe (and according to rave),i must reach a certain speed to "wake up" the slabs ecu (which thinks that the disco is on extended mode?)
When this happened,i pluged the nanocom,no errors,voltage ok on height sensors,compressor,valves but no action to level up again,i inflated the bags through nanocom..
I own the disco 3 years,at some point i switched to coils but went back to air suspension again - i am extremely pleased with sls.

The SLS is a keeper IMHO. It's simple, works well, and is easy to troubleshoot and repair ... and IS relaible. When an airspring fails, replace both. Easy job.

As it is a 2002 model,it probably doesn't have the CDL internals in the TC,i wouldn't worry,leave it as is.I had the earlier without the CDL & found it fine.The CDL is better but if your not doing extreme stuff,should be OK.See how you go.Expensive to fit if no internals.

As others have said SLS is good & reliable.

its a 2000, not 2002, and i have a 1997 TC from a defender I can scavenge the CDL from.
will it fit? And how will this affect the cost? Seems to me the biggest issue is getting difflock lever in the cab without making a mess of the trim etc
