Gen 2 SCAB rear end kicks sideways over bumps??

[carguyohio]

1) If you require a planted rear-end, you shouldn't drive a pickup.

That. My Ram 1500 RCSB will "jump" to the side at higher speeds when in a corner and hit a bump of certain size. The tires simply loose firm contact with the road for a slit second. Not an issue on dry roads, just be careful in weather.

I restored a 88 Toyota once (Back To The Future Truck). The bed was way past the point of repair and I put a fiberglass bed on it (ultra light). One winter I "skipped" a little and to complicate the roads were a little wet and slick. Went into a fishtail, did everything I could to keep that truck from rolling, but once I completed that task i was in the median heading for the other side at 45+, I narrowly avoided oncoming traffic before ditching on the other side.

T-R-U-C-K-S.

And this is not just a truck issue, although trucks do make it worse. Watch the Chevy exec hit a high spot on a corner while applying power to a ZR1..... Even the commentator mentions the issue around 1:20.

Getting ready to pull the pin on a set of 3" Deavers, longer shackles and a SVC IFP bump stop kit...yeah I know lot of cash to throw at a brand new truck, but I believe this will make a difference...

It makes a huge difference. I did the +2 and the SVC bump kit. The stock springs have like 4 leafs and are sprung way too tight making them inconsistent and twitchy. The Deaver springs have 12 leafs and are much heavier. The Deavers also help with traction in 2wd. If Ford missed the mark on any one thing in the Raptor it is without a doubt the rear springs. Ford should have used Deaver as the OEM spring.

Deavers are definitely an improvement. Stock leafs were sloppy and became sacked out pretty quickly.

My only gripe is that I have to grease the friction pads on them every so often to keep them quiet. Not a big deal tho.

Which bump kit did you go with?....I just ordered a set of +3 Deavers and the 2" IFP bump kit...going to install with longer shackles for now and then down the road throw a chase rack in the back and go back to the stock length shackles to get my stock ride height back

Can I assume they work good?....hopefully not too stiff?
Thanks

Sadly I haven't had time to really put them through their paces yet... I have hit them a few times though here in the concrete jungle of Los Angeles, where the paved roads are worse than anywhere else - yes, they are smooth as silk. You can hear them too if your windows are down, you will hear a slight click. It's like a super soft landing compared to the OEM solution.

I have the Fox 2.5" with the Schrader valve on top. You can adjust the pressure if needed for desired "stiffness." Being a SCAB, for the weight im carrying and how hard im driving 100-110 psi is perfect. In the roughest conditions I used about 85% of the travel.

You know when they hit thats for sure, when your flying theres a war going on back there. They do work great compared to the alternative of hitting that stock bump stop wall.

Any idea if the deaver +2's make the truck tow worse or better?

From the company "Most Deaver springs are not designed for heavy hauling and heavy towing." Take from that what you want.
