yeah i havent heard many good things about the Rancho Quicklifts installed on an EX. Originally they were made for all 3rd gen explorers but there was some design changes for the 04 and 05 explorers so now there are 2 different part numbers coinciding with the years. Seems like a lot of money to spend on the struts and then you still have to reuse your stock spring.
The installation of the strut spacers wasnt bad at all. Ive done everything, including strut spacer and body lift, out of my 2 car garage.
