Synergy Manufacturing 8069-04 Front Track Bar & Sector Shaft Brace Kit

Pros: Very heavy 1/4" thick plate Powder coating is thick and durable Oversized trackbar bolt holes to use with wallowed out frame holes, and oversized trackbar bolt provided This item is so good, Jeep should install them on all of their Jeeps at the factory! Best fit is with Oversized Monster (TeraFlex) or Yeti trackbars with the oversized 9/16" trackbar bushing sleeves.Cons: If you plan to use it on 2012 or later models with the factory trackbar, you must use the 14mm factory sized trackbar bolt provided, it is longer than the factory bolt, but will be small and have about 0.013" play if used with a HD trackbars that have 9/16" ID bushings. Best bet is to use SYNERGY'S trackbar, or TERAFLEX Monster, STEER SMARTS Yeti with oversize bushing sleeves. Expensive, but worth it! It will fit, but it is a tight fit between frame and coil spring. It takes some finagling and holding your mouth right. Don't give up, it will fit. I'm 66 years old, and installed with the Jeep on the garage floor no lift, no jack stands. Synergy supplies a 3.25" long 9/16"-13 NCT bolt, the one on the right in my picture. I used a Grade 8 9/16"-18 NFT bolt. It had a longer shoulder, so no threads cutting the Trackbar bushing, and fine threads are stronger too. My frame holes were wallowed just a tad, so I had to use an old used and abused 9/16" reamer I had. I put a TeraFlex Monster HD Trackbar that has the 9/16" ID bushing in it on too. Factory trackbar bushing were shot. In the pictures I have the Jeep on a jack stand on the right side, I was putting JKS trackbar axle brace on that end of the track bar. It has to be welded on. I put the trackbar on just to make sure it would work with both after market braces. It does. So it will come off, I will clean and paint, then grind weld surfaces, weld on axle brace and repaint.Make sure you torque all the bolts to the specs Synergy lists. I did with a 1/2" drive Craftsman torque wrench, with the Jeep flat footed on the garage floor, and both wheels on. It can be done. If you do jack the Jeep up to mount the brace, be sure to FINAL torque the bolts with the suspension fully loaded wheels on the floor, so the trackbar is in the right position.As others have stated with a Monster HD trackbar you will have about 1/8" clearance between the bottom through frame bolt head and the trackbar. With TERAFLEX'S Monster HD adjustable trackbar, my trackbar didn't touch until I lifted the trackbar on the axle side all the way up to the frame. See picture with trackbar held up with orange ties. It barely touched even then. Please bare in mind, my JK has no lift, it is stock suspension. If you have a lot of lift, I don't know if you would have full articulation with a heavy duty track bar. It might take grinding the head of that bottom through frame bolt just a tad after torquing. I also beefed up the axle end of the trackbar with a after market brace. Synergy makes one, as does JKS and other. Some need to be welded on, mine did. YMMV. The trackbar takes a lot of stress and strain, if you upgrade your trackbar from the wimpy factory one, I highly recommend you install this brace, and one on the axle end of the trackbar. The factory mounts are thin and weak, and once rusted and stressed with lifted and oversized tire Jeeps they will fail. The factory mounting holes will get wallowed out.

2011 Jeep Wrangler, 85,000 mi developed ‘death Wobble’ Spent $1000 on rebuilding the front end, tie rods, track bar, etc.it’s an engineering issue, this extension to the frame, is like a ‘diving board’ a flex point that allows the axle to move laterally.At speeds over 65 mph hit a bridge joint, pot hole any bump would cause the ‘Death Wobble’After this was installed, only change made. Bumps are just bumps again.I’ve hit bumps at over 70 mph that would have caused server Death Wobble. Live in Utah speed limits up to 80 mphThe front end, never felt this solid. Very happy !!Nov. 21 Update,Still happy with the results, the front end is much stiffer.On a occasion I have experienced the wobble, 75 mph hit potholenot as violent, only needed to slow down to 60 mph for it to go away.Over sized tires with 2.5” Lift

Fit well

Just installed. Research if you will need a Synergy or similar design track bar.Other than that it is a pain to put in, it seems like that helps it stay very rigid. Very well constructed and the directions were very easy to follow.In all, I feel better about my 2016 JKU Rubi running 37’s and not have a major failure on the trail.

Bolts in well. Seems solid. Haven’t had it long enough to know how durable it is, but past experience with Synergy leads me to believe it will hold up well.

I installed this brace at the same time as a PSC big bore steering gear box. Went in super easy and is a big upgrade in strength for the track bar.

this along with the sector shaft brace made a HUGE difference , i had alot of slop with 37in ko2s on my 2 door and went to 38in patagonias and ended up putting the 37s back on as i did not feel safe driving 80 down the hwy , now the 38s drive better than the kos did without the brace , cruises 80 comfortably now . The stock track bar comes really close to the nut on the sector shaft so i will be getting the synergy track bar thats built to fit this setup .

I have Sahara JKU with all stock tires and no lift. This brace reduced the steering play, and helped the Jeep to not wander when hitting road imperfections. Worth it.Installation difficulty was medium for me as I’m not a mechanic. The shop can do it under 2hrs I’m sure.** As per instructions, use M14 bolt (silver coloured) vs the slightly larger 9/16 bolt (gold coloured) when using stock track bar. You could jam in the larger bolt, but good luck taking it out.
