Thread: Lifting SLS with ACE

I raised mine 50mm without too much hassle. You need to change your shocks, get longer front springs (I installed tougher ones for load carrying but the ride is rougher) and at the rear buy some spacers that raise the airbags. Then you need to trick the ride-height sensors on the rear trailing arms with a spacer too, so they don't lower the springs back down despite the spacers! Last hint; it's better to use a slightly less than 50mm spacer, then slightly over pump the bag when setting the ride-height, to get a firmer rate of spring. Make sure the rear shocks cannot come out too long or the bag will be torn! No dislocation on these babies! Also, I made the top face of my spacer on a slight angle to match the arc the suspension arm travels through. The ACE poses no issues and although the steering is lighter, it's acceptable without castor correction at 50mm or under. Legalities? Hmm. I think some states frown on spring spacers so not sure if air bag spacers count, although I believe you can get extra height bags somewhere? Also tell your insurance; one company wouldn't insure me, another had a $600 excess but was cool with it. I made my own bits and bobs but you can buy them, google is your friend!
