Dealer. You'll never match the factory ride by going aftermarket.

Exactly my thoughts!

Hence why I say factory springs and traction blocks over aftermarket springs!

Doesn't the F450 have a different frame?

depends if it is a pickup or a chassis cab. And if it is a chassis cab, what the gvwr rating is...

Question for you hoppers.... without going through all the responses in this thread.

How many guys that have a dually or Dana 80 or a Dana 110 have the hop....

Did you guys make a brace to tie the frame by the radius arm mounts together? Also, do you sell those shocks with the special valving?

On my OBS, there is a crossmember by the front fuel tank and the trans crossmember. Both crossmembers have brackets coming off them going to the frame flanges.

You have any bounce issues on that body style?

sootie · Mar 3, 2016

the 2017 250 and 350 have fully boxed frames. i bet no more hop...

Arconalloy · Mar 3, 2016

Yea probably right ^^^, I want to get mine situated but I just don't see all that crazy bracing like that completey necessary but I've been wrong before

Layson · Mar 3, 2016

Yeah I don't think the bracing will get rid of the hop. That may improve slightly the handling but that's it... the frames are plenty strong in these trucks.

I looked at a cclb truck the other day that didn't have the hop and it had a different driveline then normal....

i can watch my entire body line in my mirror and when the hop occurs, i can see it flex between the bed and box.

live life full throttle

god bless america and the farmer who feeds your fat ass

I don't get why people want one piece drive lines. I'll still take my perfectly dialed 2 piece any day..

I much prefer my one piece shaft over that two Ive maintained for 16 years. After working on it once it becomes obvious why a single shaft is desired.

I made an adjustable bracket for my carrier bearing but its still not as smooth as a single. No spot @47 where it starts to vibrate, etc

As long as the angles match, and the carrier is adjusted I've never had a 2 piece vibrate

But on a high horsepower situation it takes so much more to make a 1 piece take what the two piece can. These guys have to make these huge driveshafts when a stock F450 2 piece takes it all day every day @ 1000..
