Hardware Parts List

1. This kit uses DJM's twin tube pivot sleeves. YOU MUST ASSEMBLE THESE SLEEVES CORRECTLY. DO NOT SKIP THIS STEP!! The sleeves are already installed in the control arms. Cut the zip tie holding the nut and inner sleeve. Remove inner sleeve and set both aside. A small hole is drilled for the grease to pass though to the inner sleeve. Although this is done at the factory, check that there is a 1/8" hole drilled through the zerk fitting hole into the bushing and outer sleeve (Fig #1). The drilling operation will leave a burr on the inside of the sleeve and must be removed. Use a rat tail file to completely remove all burrs from drilling and on the ends of the sleeves (Fig #2). Make sure you clean out any chips or dirt. Install grease fittings (Fig #3). With the outer sleeves drilled and cleaned, it is important to check the inner sleeves. These sleeves should be about .050" longer than the outer sleeve. You should assemble them before greasing to check that length is slightly longer and they rotate smoothly. Now apply some grease to the inner sleeve and insert into control arm (Fig #4). Install ball joint grease fitting (Fig #5).

   

   

   

   

   

2. Do not impact the pivot bolts. Clean bolts before installing. Replace factory nuts with nylock nuts provided with kit. Tighten to 30 lbs.

3. Before installing sway bar end links, loosen the 4 10mm bolts that hold the D-bushings to the frame. Install sway bar end links. You may need to raise arm with floor jack a little. DO NOT OVER TIGHTEN END LINKS!! 2 OR 3 THREADS PAST THE LOCK NUT IS ALL YOU NEED. Cycle the suspension to seat sway bar and tighten D-bushings. Review all procedures and check that all parts are tight and installed correctly.

   

   

4. Replace wheels and torque lug nuts. Check the tires will turn both ways without making contact. INSTALLER MUST CHECK THAT THERE IS ABSOLUTELY NO CLEARANCE PROBLEMS BETWEEN THE WHEELS AND TIRES, THE SPINDLE, THE CALIPER, THE CONTROL ARMS OR ANY OTHER COMPONENT BEFORE DRIVING VEHICLE.

5. To get the toe end close, turn the tie rod ends in about 3 full turns. Turn your steering wheel until it is straight. By sighting down the tires and truck you can get the toe fairly close. Adjustment is made with the tie rod ends. Loosen nuts at the rack and turn the tie rod ends until the tires are in a straight line from front to rear. Close is all you need, your alignment shop will correct this for you. Don't forget to tighten the nuts. TAKE YOUR TRUCK TO A QUALIFIED ALIGNMENT SHOP FOR A PROFESSIONAL ALIGNMENT. ALIGN TO FACTORY SPECS.

6. With the vehicle on ground measure height of front and record on installation helper. Your measurements should be about 2-1/2" (CA2599L-2), 3-1/2" (CA2599L-4) and 4-1/2" (CA2599L-5) less than the before measurement. REMEMBER AFTER TEST DRIVING INSPECT INSTALLATION AND DOUBLE CHECK ALL THE HARDWARE IS TIGHT.

FK2599-7 only:

Included with FK2599-6X & FK2599-7X:

Relocating (Flipping) Rear Axle

1. Reinstall the leaf spring under the axle. Place the new axle locator bracket on top of the spring, with the off center hole toward front of vehicle. This will center the rear axle and pull the drive shaft back from the transmission slightly. Lower the rear axle into the new axle supports. Rotate axle to desired pinion angle.

   

2. Install new U-bolts and spring plates (5 hole) on the bottom of the springs. Cross-torque u-bolts. Over tightening may bend spring plates. Place the new upper axle plates, with the pin down, on top of the axle. Install and tighten the 5/8" bolts provided with one flat washer on top of the upper plate and one on the bottom of the axle locator.

   For FK2599-7 & FK2599-7X, replace factory shackles with DJM shackles.

   

   

3. Installing Frame Supports. Frame supports are installed after axle is relocated. Raise the axle, and mark the center on the frame. Use this mark to center the frame support. Make a template or use one of the brackets and mark the frame. Use a sawzall, cutting wheel or plasma cutter to notch frame. Do not use a torch!! Move any wires or brake lines out of the way before cutting. Drill and bolt frame support to frame. Install bump stop on the frame support.

   

4. Before installing rear shocks, install the shock extender to the right side axle mount. This will make the shock work at a much better angle. Slide bracket over the factory mount and install the two 1/2" x 1" bolts from the outside and tighten. Line drill a 3/8" hole through the factory mount using the shock extender as a guide and install on 3/8" x 1" bolt and tighten. Now install the DJM #TS1800C driver side rear shock and the DJM #TS1900C on the passenger side.

   

5. Install rear wheels and torque lug nuts. Remove jack stand and floor jack. Test drive and adjust pinion angle as necessary. Measure and record the height of the rear on the installation helper.

6. If drive line vibration occurs, with 2 piece drive shafts, install the Carrier Bearing Bracket #CB99 (included with FK2599-6X and FK2599-7X) to correct drive line angle.
