Giant motorsports ddl kit install

[Aramco Raptor]

@ntm
When you ditched the mini dampers, how did you fix the axle housing to the lower links? Would be curious to see that.

No changes to the link to axle interface. Just tabbed the tops of those axle shock mounts to use for a sway bar link connection.

As a wrap up to this adventure, I'd have to say the ddl does not work as delivered.
The axle dampers had no hope of controlling pinion angle, regardless of valving, oil viscosity, and nitrogen pressure adjustment.
The anti squat behaviour was very poor, and required excessive damping in the bypass to tame.
And the axle shocks self destructing under braking is a no go of course.

It works great now as a third link/panhard setup, is much more durable, and should be designed and sold as such by Giant.
The bypasses should have more tubes though, as I'm stuck with single tube free bleeds now. Valving on the bypasses should be in the 15/10 range, rather than the 20/12 provided, due to the short lower links motion ratio. And spring rates should be 400/400.
I'm posting this information here, as Geoff seemed very unreceptive to the notion that the ddl will not work on a raptor.

Are you swapping it out for something different?

I wonder if that has to do with the weight and power of the raptor

I'd say so.
Geoff says he has put them on diesel f250's.
I think we might be using them harder up here than they do down south ?

street queens maybe?

Bumping this thread back to life. Just read the entire thread. Awesome write up, technical specs and feedback.

Curious where the truck is at now? Updates???

Hey @ntm can you post some of the 3 link set up. I have been building one in a computer simulator. Curious where you landed with yours.

How is this build years later? any updated photos? Interested in doing a custom build like this.
