Thanks for the tips, After having a look at the links you suggested I got onto the king springs catalogue and referenced the part numbers and now I’m a lot more confident in the springs I’ll be getting,

Gonna go with Rear KDRR-43HD (100-250kg) and Front KDFR-42HHD (100-250kg)

Has anyone used these in the front? Being the extra heavy duty option does seem excessive but with a steel bull bar, winch, dual batteries plus lights and other bits and pieces my front end is well over the 100kg limit on the heavy duty coils,

Cheers
