Giant motorsports ddl kit install

so its ready for saturday? i don't know how even stock you were never wanting more power, i personally think the truck needs more power especially in the gravel

Bedsides won't be done until the end of next week. They're getting line x coated on Monday.
I suppose stock I may have wanted more power due to having to slow down for stuff so often, but generally still traction limited.
With the long travel front and leaf rear, it was limited on a safe top speed due to random donkey kicking. So it was pretty much traction limited power wise in that speed range as well, except for on smoother, damp, hard packed clay.

Now you can more or less hold it down until you run out of nerve, so spending more time accelerating in the 60 to 100 mph range, where it does feel a bit more sluggish. I'm still running 4.10 gearing with 37's... Can't bring myself to regear the stock axle since I plan on changing to a 9" as soon as possible.

ya after doing a few more runs in the truck I'm thinking i may be regretting my tire choice with the 37" red letters i have in the basement waiting for rims. when you go to the 9" are you going to run a 10" gearset, or do you think it would not be needed?

No 10" if I stay with the Ddl setup, if I get silly and decide to do a full four link this winter, then 10".
Those axle torsion bumps really seem to damp any driveline shock compared to a traditional three or four link...
The 37 red letters would need some healthy gearing just going by the 35 red letters I had. 37's with lower pressure really smooth things out off road though, they are worth the trouble and short steering rack life.

Looks ****** sick all painted up.

looking forward to finally seeing this beast in action this weekend

Well, it was blazing fast for about 15 minutes in the sand trails/whoops.
Under hard deceleration one of the axle control shocks went bang:

this is what I found on disassembly:









That's a fundamental design issue, there's no way to strengthen those shafts sufficiently that I can see. So I've got parts on the way to truss the axle and mount a third link that will control pinion angle and absorb those compression/tension loads that the axle shocks were unable to cope with.
I will strongly urge Geoff to change this over to a three link kit.

Looks like it could have used some more thread engagement on the nut, but looks like that would not have been enough.

It had thread showing out the backside of the nut.
I'd give it one more chance, but I've heard of this happening on a tundra as well.
And I was just feeling it out, wasn't even getting violent with it.

Yikes... that's concerning. I know you had the air shocks charged up pretty high, do you recall your final psi?
I was considering ramping up the pressure a bit, but am wondering if that can contribute to a failure.
