Just wondering if someone can tell me the difference in King Springs between KHFL-150SSL+ and KHFL-150SSLHD+.
I understand what the SSL refers to, but can't find any information on what the HD means.
Thanks
Cool thanks for that, thought it was some simple like that. Appreciate the quick response
Heavy duty is obviously recomended for carrying loads or towing regularly, in my case i have a stereo installed which adds a bit of weight and i tow quite often so i have them in the rear. and it rides really well! just so you get an idea
