Addco Larger Front Sway Bar

[JCruz]

If anyone else is interested I arranged for Addco to manufacture an upgraded front sway bar. We began the conversation in March and I just got word that my bar will be shipped next week. I shipped a factory OEM bar for them to reference.

From Addco:
The OE bar is 27.5mm, ours is 32mm. The stiffness increased 76%.

The factory end links should be good, they are typically higher quality than those available in the aftermarket.

Since this is something I will add to my catalog there will be no charge to you. The retail price is $304.72. Lead time will be 8 weeks.

I will give feedback once it’s installed .

Good people to work with.

Nice!

I am used to Addco specifying performance changes with their products so I am curious how this is going to improve cornering power.

Pair this to the Hellwig rear (or maybe Addco will bring one to market) and street handling may really be enjoyable.

Quicm disconnects would pair nicely.

Sounds interesting. Almost certain my 2021 has plastic anti sway bar end links, so not sure how durable they will be long term.

Not sure what the objective is here to make such a substantive change and create a huge change in understeer. Really screws up Roll stiffness balance. Not a change I would make without some increase in Springs or additional bar for the rear... Ford Vehicle Dynamics will always create a bit of push as customers are comfortable with push....But not that much as 76%...

Best,
Phil

Not to mention 76% increase in bobble head action...good call Phil...

Phil, Thank you for your input!
I really appreciate your expertise I am a rookie at this and will now reevaluate.

Wow,

I installed an ADDCO brand rear sway-bar on my 2wd 2k4 Tacoma years ago. [2014/2015]

The kit was supplied with crappy hardware that initially had to go to Home-Depot/Lowes to source replacement nuts & bolts...
I tried BOTH emailing & calling ADDCO directly for replacement nuts & bolts.... all they did was take down my info & claimed it was in the mail...
NEVER received anything from them. Even after both calling & emailing them every month for six months.

Plus their swaybar bushings & endlink bushings were junk after a couple of years where I had to source true-polyurethene bushings from Energy-Suspension & Prothene Companies.

I will NEVER use or recommend ADDCO...

HI John,

This may work for you just fine.....I think you will notice a very large degradation in rough road ride as well as an increased push in handling and it may manifest itself in being more than the shocks can dampen. This in turn can increase front suspension loadings above design criteria... You many end up chasing the rabbit through both front and rear suspension. It depends on what you are looking to do with your truck.

Some balance can be achieved with a Helwig rear bar or Addco if they make or plan to make one.

Here is something folks rarely know. Bar stiffness is proportional the the 4th power of the diameter of the bar, so slight changes in diameter make huge differences.... Example. Double the diameter or twice...so we have 2x2x2x2=16 or sixteen times as stiff.... For my SCCA racetrucks before the blade adjustable bars we tuned in increments of 1/16th of an inch in diameter change... Blades are a different animal and worked fabously...but that is another story

Good luck!

Best,
Phil
