INSTALLATION INSTRUCTIONS

1. Raise the front of the vehicle and support with safety stands under the frame rails. Take care not to over extend the

stock brake lines.

2. Remove the front wheels and tires. Remove front stock shocks. Retain the lower shock hardware for reuse.

3. Support the front axle housing with a floor jack (you must have stands under frame supporting vehicle weight).

4. Remove the stock sway bar links from the sway bar and the spring pads. It may be necessary to tap the upper link

on the sway bar with a hammer to release the tapered pin. See Photo 1.

5. Unbolt track bar from the axle mount on the passenger side of the front axle as shown in Photo 2 and then tie the

bar up and out of the way.

6. Remove the stock brake hose bracket from the top of the frame rail by removing the one bolt located directly behind

the shock towers. (Access can be gained through the engine compartment). Retain the factory torx head bolt for re-

use.

7. Remove the four front spring to axle u-bolts. See Photo 3. (The remainder of the spring removal and installation is

performed one side at a time.)

8. On the driver side position a floor jack under the axle tube, just inside of the leaf spring. Raise the jack until the axle

just separates from the spring. Now remove the frame bolts and the shackle bolts on the leaf spring. Retain hard-

ware for reuse. See Photo 4. Remove the stock spring.

9. Repeat on the other side.

10. Prior to installation of new springs, thoroughly lubricate the new spring poly eye bushings and sleeves with a water

resistant, lithium based grease. Loosely attach the spring (front spring part number is 8010) to its hangers with the

stock bolts, washers & nuts (unless optional spring bolt package 1184 was purchased). Note that small spring eye

goes to shackle end. Snug up but do not completely tighten. Make sure spring tie bolt heads align and seat into

spring perch holes.

11. Install new u-bolts. Tighten u-bolts to 65 ft. lbs. of torque. Tighten spring pivot bolts to 35ft. lbs. on both frame

mounts and shackle mounts.
