I found just about zero consumer sourced info on this steering system as it is relatively new, so I hope I can help someone else decide to order it for their truck from Paul at CJC Off Road.
Synergy Manufacturing Dodge Ram 2500/3500 Heavy Duty Steering Kit
I just got through doing the suspension on my truck. I have been doing my homework and planning out exactly what I wanted under my truck since about June of 2011 or so, when I first got into my '95 360/NV4500 truck. I went through a few Dodges of varying vintages before I settled on my '04 as being "the one". Meaning the one that was worth me building to be my long term keeper, not worrying about getting my money back out of it etc.
Over the course of that time I have always kept my eye on what's going on with suspension and steering in these trucks, who is making the best stuff for the right value, etc. I am also a big 4x4 nut, I have been reading the 4x4 magazines and surfing Pirate4x4 since way before I had my drivers licence. I have read all kinds of reviews, impressions, and experiences with every steering and suspension setup under the sun. Why this works, that doesn't, and why they did this from the factory.
I have watched every steering setup that comes out looking like the ticket end up having some sort of design flaw. There are some almost great options available that have a flaw or characteristic that turned me off for one reason or another.
My truck is my daily driver. I haul motorcycles of many varieties on a regular basis. I tow cars alive and dead. I tow my Jeep. I drive long distances a couple times a year, with or without the trailer. I need to be able to get into the hills on rough roads and be comfortable on the interstate for 10+ hours when the occasion arises.
My requirements were this.
-T-link (No Crossover for a 3" lift, no Y-link)
-No Drilling (Why? Unnecessary modification is great on my Jeep, not on my DD)
-I don't like heims. In general. I have to run them for clearance reasons on my drag link on my Jeep, but I don't want them on my DD.
-Tough and serviceable
These requirements narrowed it down to pretty slim pickings. I read about lots of guys going to the 08.5 steering, being dissatisfied with it, and then continuing to replace it over and over. I would rather spend more money (even a lot more) only once. Thankfully EMF and Synergy recently released some sweet options that fit the bill!
I was planning on EMF steering until I read Rhinopkc's Product Spotlight on this system.
I was a bit hesitant about going with a product from a big (relatively speaking) company, but his personal testing of the product sold me on the durability and quality of it. At $750, it is about 1/2 the cost of the EMF system. I have ZERO experience with EMF or their product. I fully believe their product is probably the baddest steering setup available, but if the Synergy steering is good enough for Paul's truck, it's beyond good enough for my application. Also, a benefit of going with a product from a bigger-ish company is that replacement wear parts are likely to be around for a while. I ordered the Synergy steering.
It came packaged very thoughtfully in 3 different boxes. There were separate instructions for the tie rod and drag link. I also received double the hardware for the tie rod, but that is irrelevant. I got a total of 4 stickers. I like stickers.
The tie rod is 4130 1.5" diameter 3/16" wall heat treated chromoly tube.
The drag link is 1018 cold rolled solid 1.5" steel bar.
The adjusters are pretty trick, and work very well. They allow the links to be adjusted from one side only, without removing any tie rod ends. A pinch bolt secures them so that they don't move on their own.
It comes with a matching steering stabilizer bracket as well. Some other retailers advertise a lower price, but do not include the bracket at that price.
As you can see everything comes powder coated in a sweet gun metal grey metallic color. The tie rod ends themselves are a Synergy Rod end, no plastic inside like OEM style stuff, all metal.
CJC Off Road even offers the 08.5 style pitman arm at an awesome price when purchased with this steering (it's necessary), WAY less than it costs to source one separately.
Time to install it on the truck! I ended up replacing my steering gearbox with a reman from Redhead, but if you use the gearbox that is already on the truck, and have a 03-08 Y-link steering, you'll need to remove the pitman arm in addition to the old junk steering. Torque spec on the 1 5/16" pitman arm nut is 225 ft/lbs. The rest of the info needed for install is in the Synergy instructions. It was all very easy and fit together very nicely, I enjoyed the install. Here's a few pics of it under the truck.
Angles are all very nice, fit and finish is great, and it looks killer under there. I feel that the geometry is much simpler and sensible than the factory Y-link.
As far as driving goes, I put a few hundred miles on the truck with the lift installed, but still running the Y-link, so I was able to get a true "controlled" experience of replacing just the steering. The initial install of the lift included Thuren 3" springs/shocks, Carli track bar, Carli ball joints, and Synergy shackles. So the front end is all fresh, the unit hubs have no play. My Y-link had some mileage on it, but there was NO slop or play in any of the joints. I even greased it up when I put the lift on. My steering stabilizer is functionally in great shape. My old steering box was in perfect shape, I only replaced it because I cracked the cap trying to pull the pitman arm without a puller (My cheap one broke a while ago, just go buy the puller). I never once had any problems with death wobble. All that being said, going from the Y-link to the Synergy T-link completely changed the way the truck drives. I can't express how much I loathe the entire idea of a Y-link. Every time the suspension moves the slightest bit, the toe angle changes. With stock tires and factory suspension it's not the end of the world, but even when I was bone stock I could feel it doing weird things during some cornering situations. Bump steer was present with the Y-link, not bad, but present. This well designed T-link transformed the truck into a sports car. I can now plow over anything the suspension can handle without any bump steer. Steering through corners whether fast, slow, bumpy or smooth is now predictable and precise. There is no "dead spot" in the steering that is sometimes associated with a T-link. It drives down the freeway perfectly. The truck drives better than any of the Dodge 4th gen company trucks that I drive regularly for work, and they are all well maintained.
I will update this periodically as I put miles on this setup, but initial impressions have me fully satisfied with my purchase. I want to say thanks again to Paul at CJC for "steering" me in the right direction for putting together my suspension and steering package. Give him a call, he has personal experience with a huge amount of aftermarket off road products available for our Dodges.
