what is different about the fx4?
hey, does anyone know the difference between the fx4 and and regular stx or xlt, besides having bigger rims and tires, is there any difference in the shocks or suspension?
The xlt's have the 9.75" rear axle as well. You could get an 8.8" on the stx trucks. My xlt was optioned with the same skid plates as an fx4. Most of the time, it depends on how the truck is optioned for exterior components. The interior always has the fx4 cluster and center shift. Same fenders just plastic fender flares added. They did not come leveled, but did have rancho branded shocks.
