Mr B Posted June 20, 2019 Share Posted June 20, 2019 (edited) the self levelling rear suspension (SLS) is mechanical design within the strut . only people who supply the SLS type shock is Subaru, if your shocks where after market such as and hopefully KYB excel g (normally are as Subaru SLS struts are about £350 each) they need pairing with non SLS springs as they different spec or even better if towing a lot you want springcoil.co.uk make you custom set with + 20mm ride height and stiffer rating . When you use the old original SLS spring with new non SLS shock you get same issue as on the old shock with rear sagging as spring is 1mm thinner diameter on the SLS strut as the original SLS strut hydraulically assists the spring . Also worth checking the right shocks fitted, many times later SG shocks may get used and spring platform position differs on those . Most average garages are clueless on all this thus a serious hash up you get pay for . Edited June 20, 2019 by Mr B Quote Link to comment Share on other sites More sharing options...
