Learn how to install 2.5-inch coil spacers on a 1994-2012 Dodge Ram 2500 or 3500 4WD. Step-by-step instructions with common mistakes and checkpoints.
Quick Answer
Installing 2.5-inch coil spacers on a 1994-2012 Dodge Ram 2500 or 3500 4WD is a bolt-on project that lifts the front end without replacing springs. You can return to stock easily, and the process takes about two hours with basic hand tools.
Why Use Coil Spacers Instead of New Springs?
Coil spacers sit on top of the factory spring to add lift without changing spring rate or ride quality. This keeps the stock ride feel while accommodating larger wheels and tires. The trade-off is that you get no additional load capacity or articulation—if you need those, a full spring replacement is a better choice.
The Body Armor 4x4 2.5-inch coil spacer is designed specifically for 1994-2012 Dodge Ram 2500 and 3500 4WD trucks. It uses a durable powder coat finish and comes with the Armor Guard warranty.
Step-by-Step Installation
- Step 1: Lift and Support the Truck: Park on level ground, chock the rear wheels, and jack up the front axle until the tires are off the ground. Place jack stands under the frame rails behind the lower control arm mounts. Never work under a truck supported only by a jack. Common mistake: placing stands under the axle instead of the frame. This compresses the spring and makes spacer installation harder.
- Step 2: Remove the Wheel and Shock: Remove the front wheel. Then unbolt the lower shock mount using a 21mm socket. Compress the shock by hand and swing the lower end out of the way. You don't need to remove the upper shock mount. Checkpoint: if the shock is seized, spray penetrating oil on the lower bolt 15 minutes before starting.
- Step 3: Disconnect the Sway Bar Link: Remove the nut from the sway bar end link using an 18mm wrench. Separate the link from the lower control arm. This allows the axle to droop fully so you can access the coil spring. Common mistake: forcing the axle down without disconnecting the sway bar can damage the link or tear a bushing.
- Step 4: Lower the Axle and Remove the Spring: Place a floor jack under the axle tube near the spring seat. Slowly lower the jack until the spring is loose. Remove the spring by tilting it out of the upper and lower pockets. Watch for the rubber isolator—it may stick to the upper mount. Checkpoint: if the spring is stuck, lower the axle a bit more. Never pry the spring out with a metal bar, as it can damage the powder coat.
- Step 5: Install the Coil Spacer: Set the Body Armor 4x4 coil spacer on top of the spring, aligning the locator tabs with the spring coil. The spacer sits between the spring and the upper mount. Reinstall the spring assembly into the pockets, then raise the axle with the floor jack until the spring seats fully. Common mistake: installing the spacer upside down. The flat side faces the upper mount, and the recessed side faces the spring.
- Step 6: Reassemble and Repeat: Reattach the sway bar link and torque the nut to 30 ft-lbs. Reinstall the shock and torque the lower bolt to 50 ft-lbs. Mount the wheel and torque the lug nuts to 140 ft-lbs. Repeat steps 1–6 on the other side. Checkpoint: after both sides are done, lower the truck and bounce the front end a few times to settle the suspension before driving.
