Synergy Rear Trackbar bracket and Trackbar

Synergy Rear Track Bar Relocation Bracket and
Synergy Adjustable Rear Trackbar

Part #: PPM-8056 / PPM-8062

I finally decided to install the Synergy rear track bar brace and adjustable track bar that has been laying on a shelf in my garage for some time. I never did weld the Rockkrawler track bar bracket in place and amazingly I didn't have any issues with it. I figured I would, so I guess I was just lucky. Synergy (Poly Performance) has built a lot of quality stuff over the years. I've seen some of their stuff take some real abuse and survive. I had decided a long time ago that I was going to install some 3.5" springs on the Jeep to replace the Rockkrawler springs when they wore out (that was 5 years ago). They haven't changed much, still look good under the Jeep, so I will probably pass them onto someone else to run for a while. I did need center the rear axle just a little, about 1/4" on the adjustment, so you can see why I just left it sitting on the shelf. You can either install both, or just one of the other of these parts as you need to. I installed both, but I will make note of any differences in the steps.

Additional Parts:

Installing the Rear Track Bar Relocation Bracket
The Parts:
The Trackbar Bracket
 
Installation:
1. Chock the front tires and jack up the rear axle. Support it with Jack Stands. Remove the passenger rear tire to gain access to the frame side trackbar bracket. You will need a 19mm or 3/4" socket, lug nut key, or whatever size your lug nuts are. Put these somewhere safe, because on the floor will end up kicked under every object elsewhere in the garage. Though hide and go seek the lug nut can be a fun time waster if you have nothing better to do. Done this more than once... It is possible to do this without removing the tire, but it's just easier to get to that bolt on the frame for the trackbar.
2. Remove the bolt holding the factory rear track bar to the axle bracket. You will need a 21mm socket and ratchet. In my case I needed to remove the existing track bar bracket also.
3. Loosen the trackbar frame bracket bolt with a 21mm socket, ratchet and combo wrench. If you are installing the Adjustable Trackbar you will need to remove the bolt.
4. Cut part of the factory track bar off as show in the pictures. I used a saws all and got everything fairly flush. It was a lot easier than trying to get in there with an angle grinder or torch. If you decide you need to use those, then I recommend removing the driver side shock. Keep this part just incase you ever need to go back to stock. You won't be able to go back to the factory trackbar without haveing to reweld this part on.
5. Grind down any tabs that were left sticking out when you cut the bracket off. The new bracket will need to sit flush. Touch up the grind marks with some paint to prevent rusting.
6. Attach the new trackbar relocation bracket to the facory bracket as shown with the new 9/16" bolt and locknut. Place a flat washer under the bolt head and lock nut. You will need a 13/16" socket for the bolt head and a 7/8" combo wrench to slide down onto the nut. Watch your fingers so they don't get pinched.
7. Check the front side of the axle tube for a weld. On some rear axle houseing there is a weld along the front of the axle tube opposite of the trackbar barcket. Grind the weld down just were it goes under the u-bolt so that the u-bolt contacts the entire tube. You can see how the U-bolts hit the weld. Touch up the grind marks with some paint to prevent rusting.
8. Install the u-bolts over the axle tube and through the track bar relocation bracket, Use a flat washer and nylock nut to secure the u-bolt. Torque all the bolts down. If you are installing the Adjustable Track Bar skip down to the Adjustable Track Bar section. You will need a 9/16" socket and/or Combo wrench.
9. If you removed your tire, reinstall it, and lower the Jeep to the ground. Do not push on the Jeep with it sitting on the Jack Stands. You are laying underneath it.....

 

10. You can now reinstall your factory track bar. Attach the track bar to the new track bar relocation bracket using the factory nut and bolt. You may need to get someone to push the vehicle side to side to align the trackbar bolt with the bracket. Tighten the trackbar bolts to 125ft-lbs.

 

The track bar bolt my rub the coil spring on some applications. This is often due to spring bowing because the pinion angle has incresed. Some solutions are:

1. Trim the end of the bolt sticking out through the nut.
2. Flip the bolt around so the head in adjacent to the spring.
3. Rotate the spring so the bolt is inbetween the coils.
4. Cut and rotate the lower spring mounts
5. Install lower coil wedges.

You may still need to install Synergy's Rear Adjustable Track Bar to further center you axle.

Comparison between the factory and Synergy's adjustable trackbar. The track bar is pre assembled with all the necessary components, except the pinch bolt and spacer sleeves.
 
Installing the Adjustable Trackbar:
You can skip the first three steps if you are installing this along with the Track Bar Relocation Bracket from above.
1. Chock the front tires and jack up the rear axle. Support it with Jack Stands. Remove the passenger rear tire to gain access to the frame side trackbar bracket. You will need a 19mm or 3/4" socket, lug nut key, or whatever size your lug nuts are. Put these somewhere safe, because on the floor will end up kicked under every object elsewhere in the garage. Though hide and go seek the lug nut can be a fun time waster if you have nothing better to do. Done this more than once... It is possible to do this without removing the tire, but it's just easier to get to that bolt on the frame for the trackbar.
2. Remove the bolt holding the factory rear track bar to the axle bracket. You will need a 21mm socket and ratchet. In my case I needed to remove the existing track bar bracket also.
3. Loosen the trackbar frame bracket bolt with a 21mm socket, ratchet and combo wrench. If you are installing the Adjustable Trackbar you will need to remove the bolt.
4. Test fit the spacers in the Heim joint on the adjustable track bar. These were machine very nicely and didn't have any burr's on them that needed to be filed down to allow them to slide in. I actually just left them sitting in the end, they were nice and snug so I figured they wouldn't fall out when I installed the bar.
5. Install the pinch bolt into the adjustable track bar. I recommend installing it so that the nut is facing towards the back of the vehicle. Much easier to tighten down the nut that way. The picture shows it in the other direction. I flipped it before installing it.
6. Install the adjustable track bar with the bend toward the back so it clears the differential cover.
7. Position the bushing at the frame end and install the factory track bar mounting bolt. You don't need to torque this yet, just snug it up. Synergy recommends that you install the frame bolt from front to rear. I installed mine the way it was from the factory, but I have spring correction wedges installed so I don't have the clearance issue with the spring.
8. If you removed your tire, reinstall it, and lower the Jeep to the ground. Do not push on the Jeep with it sitting on the Jack Stands. You are laying underneath it.....
9. Install the adjustable rod end at the axle end with the factory track bar mounting bolt. It helps to have someone push the chassis side to side to help align the bushing to the bracket hole when inserting the bolt.

10. Center the axle by turning the adjuster sleeve, counterclockwise will extend the track bar. Use a ¼” punch or similar tool to turn the adjuster sleeve.

 

11. Once you have the axle centered tighten the pinch bolt to 80 ft-lbs. You will need a 3/4" socket and Combo wrench.
Note: After tightening the pinch bolt, try to spin the adjuster sleeve. Make sure the pinch bolt has adequately clamped onto the rod end shank so that the adjuster is not movable. If movable, increase torque on pinch bolt but do not exceed 90 ft-lbs.

 

The track bar bolt my rub the coil spring on some applications. This is often due to spring bowing because the pinion angle has incresed. Some solutions are:

1. Trim the end of the bolt sticking out through the nut.
2. Flip the bolt around so the head in adjacent to the spring.
3. Rotate the spring so the bolt is inbetween the coils.
4. Cut and rotate the lower spring mounts
5. Install lower coil wedges.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work.
