3" Coil-over Suspension Kit (3.5" Axle) - 2003-2013 Dodge 3/4 & 1 Ton 4WD Diesel

Part # 690FCO-3.5AXLE

This addition to the heavy-duty Ram coilover conversion lineup rounds out the lift height offerings for these vehicles. You can now choose a coilover upgrade for all 3", 6" and 8" lift options available.

The new 3" system is built as an upgrade to our popular 691H 3" Dual Rate Coil lift system with the coilovers replacing the 3" coil springs and working alongside the existing front and rear box kits.

The new coilovers provide a full 8" of suspension travel in order to maximize the performance of the short arm suspension setup. In addition to the coilovers and coilover mount kit (same as uses with the 6" and 8" kits), the front box kit includes an adjustable front track bar, replacement extended sway bar links and a complete set of greaseable upper and lower control arms.

The rear is lifted via a 2" block and u-bolts. Fox 2.0 shocks round out the rear.
