Fox 2.0 Performance IFP Front & Rear Shock Kit | 2003-2013 Ram 2500/3500 2WD/4WD | 4-6 in Lift
Good to know before you buy
Fits
- 2003-2013 Ram 2500/3500 2WD/4WD, leaf-spring rear, with a 4 to 6 in lift kit (4 to 6 in front, 4 to 6 in rear)
Does not fit: stock or leveled trucks, trucks lifted under 4 in (use the 2-4 in kit), factory air ride
Why this kit
Most 4.5 and 6 in Ram HD lift kits ship with basic shocks or none at all. This kit is the Fox 2.0 upgrade for that truck: two 985-24-023 fronts for 4 to 6 in of front lift and two 985-24-024 rears for 4 to 6 in of rear lift on the leaf-sprung third and fourth generation 2500/3500. Each is a 2 in aluminum-body monotube with an internal floating piston and FOX's race-developed high-flow piston, so a tall Cummins on 35s or 37s stops wallowing over dips and keeps its composure on washboard. Both lengths preserve full travel at the lifted ride height.

Questions
My lift kit came with shocks. Why swap?
Most 4-6 in Ram HD kits ship with nitro-charged twin-tubes as the base option. The FOX 2.0 is the common upgrade, uses the same mounts, and holds its damping on washboard and under a trailer where a twin-tube fades.
Does this fit a Power Wagon?
Yes, FOX lists these part numbers for the Power Wagon at the same lift heights.
How long does installation take?
Rears are 20 to 30 minutes per side. Fronts on the Ram solid axle are a bolt-in shock, about 30 to 45 minutes per side, no spring compressor needed.
What is the warranty?
FOX covers 2.0 and 2.5 Performance Series IFP shocks purchased after 3/30/2025 with a limited lifetime warranty against defects, to the original retail owner through the original place of purchase. Keep your Hannah Suspension order confirmation.
