The launch of the all new Ford "Super Duty" in 2001 brought a frenzy of excitement to Blue Oval truck enthusiasts. A new diesel motor and a new solid axle front suspension lent itself to ease of modification and RCD Suspension capitalized on this new and popular platform. 2005 brought a whole new platform, eliminating the poor riding leaf springs and putting coils and radius arms in their place. RCD Suspension engineers capitalized on this and put together three systems, 2" Leveling, 4" Standard, and the premium 6" Long Arm 4 Link Conversion Kit. RCD Suspension continues to produce systems for most F-250 / F-350 models from 2001 through 2008 model years.
The RCD 4" Suspension System for the 2005 - 2007 Ford F250 / 350 8-Lug, 4WD includes: Progressive rate coil springs made from high quality U.S. spring steel, providing long life, and superior ride characteristics; Fox Performance Series shock absorbers; heavy duty 1/4" thick mounting brackets provide enhanced strength and alignment characteristics; 3/8" plate steel extreme duty track bar drop bracket eliminates bump steer and provides the ultimate in strength and durabilit; forged steel drop pitman arm maintains precise steering geometry; extended sway bar links provide factory mounting locations and proper sway bar function; stainless steel extended front brake lines; and unique "Gator Black" polyurethane powder coat finish.
