HI PSI Member 1,572 Member For: 17y 11m 2d Gender: Male Location: Central Queensland Posted 28/03/10 09:29 AM Share Posted 28/03/10 09:29 AM I do have this combo - with 19's - except when I used to work at Kings I always thought that the rears were a little too soft, so I had them make some SSLHD slightly higher load rating than normal and damn are they tight though bends, with no noticable difference in ride quality.Thanks for the advice... Would this option cost extra and would a special order have to be made to get them? My SL springs have gone a bit soft and sagged a bit... Especially the front.. So I am looking to replace them..

If you call them to ask about them Laurie the R&D bloke will know what to make up. They were a one off prototype but should still be on the system. Ill pm you my name if you want them and they can look up the exact specs that I had.I still cant believe these never became part of the catalogue. I kept telling them how great they were.

It's wired but that's what it is. Don't make the same mistake I did reading all this sh*t just call a shop that specialises in king springs and ask them I've read over nearly every ba lowering forum and everyone has a different idea of what's low so just call up and do it to the hight you want around tire to gard hight is ultras for my xr6 1 Link to comment Share on other sites More sharing options...
