Got one for you

[TNRGreene]

2 trucks, one question
First has a triangulated 4 link, 1 leaf spring & solid block in the rear instead of bump stops. Front has adjustable bump stops, Rs 9000's & Cv's slighly negative.

2nd has factory rear suspension, bump stops, long bars. Front has t bolts in glove box, stock shocks.

Both hang weight, both have agressive tires up front & A/T's in the back. Fronts both have sleeves & center links

At a hook last night both hopped so bad they have to lift. WTH

Looked like a pretty shitty track to me. What tire pressures were u guys running?

 

[RichLMM]

seems like it was just the sandy track and maybe pressures a little hard for the sand?

 

[TNRGreene]

This is a must though. This happened about 5 hooks in & 15 trucks/tractors before us.

Tires were:
25 front
39 rears

I hated to see the only Duramax's there not pull like they should, but it was seeing you Todd! I just figured it was the track....

Did they even drag anything to compact it or just run the semi empty up and down the track?

I wonder when the tracks that soft if you might need some weight in the bed instead of out front. We have some soft tracks but nothing that bad. I've gone as low as 30 in my duals and 18 in my fronts on really soft tracks but I don't think thats your problem. With no weight on the sled and all that weight up front it looks like that is making the rear end chatter.

Soft track

I'm leaf sprung at all 4 corners and on a biting track where I can hook and load the suspension (and keep it loaded).....balls to the walls. On a loose track where the tires try to bite and find nothing, or bite a little then nothing (as the suspension loads and unloads) it chatters. Tire pressure and weight distribution help but cannot negate all of it (especially if it's really soft). We were on a really loose track on Saturday with very similar results.

I might get a "bounce" on a hard track, but it chatters on the loose stuff.

Def too high of pressures. When I take my truck on the sand without dropping pressures it does the exact same thing. Drop the PSI and smooth as butter. Cant bounce a flat ball...
