I need extended shocks for my trailer which is made from the a$$ end of an 87 Ranger. It has a 7.5 rear end and a 4 inch lift. Autozone says I can use the factory shock up to 3 inches, but don't list anything beyond 3 inches. Is there another truck I can use some from? My 96 shocks appear to be different (maybe because it is an 8.8 rear?).
