Hi-Jack continued...

Pulled the trigger last weekend on a 2015 F150 3.5L EB with 56K miles. So far the truck is a dream.

I really like the layout of the F150 over the Hemi.

What axles came under the 14+ 2500 trucks? AAM?

Anything change with the 6.4s over the years?

For 2014-18:

Front AAM 9.25
Rear AAM 11.5

Those may have changed in 2019, but Im not sure.

Not sure if anything has changed on the 6.4 over the years. Seems like some people have issues with the mds system. You can go with the hellcat delete, and it addresses the issue.

What years are the radius arms vs the 5 link?

19 gets the HD8speed auto. I haven't driven one but have read reviews. All of them were extremely positive.

D45 03-29-2019 10:22 AM

All the previous year trucks use the 6 speed auto......Dodge, Ford, GM

Ram 6.4L
410 HP @ 5600
429 TQ @ 4000

Ford 6.2L
385 HP @ 5750
430 TQ @ 3800

GM 6.0L
360 HP @ 5400
380 TQ @ 4200

GM 6.2L
420 HP @ 5600
460 TQ @ 4100

Does the GM 6.2L require premium fuel?

gunracer1 03-29-2019 10:32 AM

IIRC you need premium to see the 420/460 numbers but is still just fine on 87.

I have my eye on a 2015 2500 with the 6.4L

Not a fan of the rear coil setup.......rides great for a 2500, but I have heard that it sags fast under load

Any issues with the 2015 model year?

Dont know of any issues specifically.

I would suggest finding a truck with 4.10s if possible if you plan to tow a lot.

The springs are only part of the problem, the rear track bar is the other issue. The problem seems to be when the truck starts cycling a lot, the rear track bar causes a decent side to side motion. When towing this can cause some instability. The stock springs are progressive, the initial is fairly light, and then a much heavier 500ish lb/in rate. You basically want a decent amount of tongue weight to get the rear well into the secondary spring rate and keep it planted.

I swapped in some 1" taller lower rate soft ride coils in the back to get rid of some of the harshness. I then found it had too much "but wiggle" when hitting large bumps and dips at highway speeds. Towing was fine however as the suspension sagged a bit. I threw a 3" rear track bar raise on it and that fixed that issue when empty. Its solid and drives great now. I do wonder if a track bar raise would benefit a stock height truck also.

These are the only problems I've seen so far. I do wonder if the rear link design being so high and leveraged on the rear axle will cause premature bushing wear? The rear bushings are larger than any I've ever seen on a 3/4 or 1ton truck however.

Not sure if it's the same engine but my tuner buddy was saying that the pistons in the 6.4 are weak if you want to do power adders of some sort. They did that in the challengers so you could buy the 6.4 and throw a blower on it and have a hellcat for less.

Would a 2015 Power Wagon have coils then?

Yes, 2014+ will have the coil sprung rear. It will also have 4.10 gears instead of the 4.56 in the 2013 and older PW.
