2017-2021 Super Duty Lift Points

[CRF250Rider]

I just finished installing my two post lift (Challenger SA10) and was reading the ALI lifting guide. For anyone who has a super duty, where do you place the lift arms? I am not very fond of the radius arms as specified in the ALI book because it would not allow for front end work to be completed easily. I saw this on the Atlas website, but I would rather be on the frame with the frame engaging truck adapters.

Thanks!

Depends on how your truck is configured. You need to find the safe balance points. Trying different configs at low heights is probably your best bet. Frame, Leavespring mounts, and such are usually safe locations to lift from. Aligning the truck('s balance point) against the centerpoint (lift post in most cases) is important. Service boxes, flatbeds, pickup bed, box, etc will all change that along with the amount of stuff you have in it.

I scaled my truck and calculated the balance point to be almost exactly at the driver’s door handle. I am going to center that on the post so that all arms should be loaded equally. Mine is a 2018 F250 CCSB with the 6.7 diesel so there is definitely some weight up front. I scaled at 7980 with just fuel and myself in it!

Only thing to watch is read driver side arm which is next to gas tank. I got frame extensions as mine is so close. Just f150 but tank is same locations.

Radius arm under the bolt to bracket eye
Lift them all there and it’s only ever affected me once out of 10,000 times

I will have to take a look at that. How far from the end of the radius arm are you placing the pad? I just wonder why ALI listed the radius arm when that wouldn’t allow the front suspension to droop out which is one of the main reasons for getting a two post lift. For tire rotations and oil changes I see no problem with the radius arm though!

Because with modern long radius arm suspensions that the only option you have to lift them safely with proper arm spread.... late model dodges even have a flat bar welded to the angled radius arm for a spot for you to lift safely on...


I lift directly under bolt on the fords

What do you feel you need to do that the suspension has to “hang”. Unless your doing lift kits all the time it won’t effect you, as it’s in 95% droop already when being picked up there

The radius arm bushings/brackets don’t go bad.....


Lifting in the trans crossmember would effect me more often in the repair work than that...

Also lift all 2005-2016 off radius arms. The 2005-2010 you can get frame also behind it. The 2011-2016 not many good options other than radius arm.

You can see in this 15 there isn’t a good spot other than radius arm to lift frame without getting to far back if I had whole truck up like I did during disassembly.

I work on the daily, do major power train work and lifting by radius arm has never been bad to me other than a crash repair radius arm replacement. Only thing in day to day problem will be thinking your doing lift kits all the time, at that point lift it the same and use a pole jack under front frame horn to remove some weight transfer till coil spring is light

I’ve gone so far as to make home made lifting arms for cabs to be faster,.... so if lifting by radius arms was a problem I’d have a solution

 

[CRF250Rider]

I see what you are saying now. I don’t have plans to do a lift kit... yet.

I’ve been lifting from the radius arm since they came out with out issue. Both Ford and Ram have the same lift point at the arm. It does make it interesting to do front end work but we just use the frame just behind the arm and do it on the ground with a creeper chair. Basically the coil, arm, and complete axle housing are the only things you would need to lift from the frame to do work.

I run quite a few Super Dutys through my shop and just like the guys above me, they all get raised with the front pads on the radius arms.

I believe there was one time the hired man raised one on the frame or ****** cross member because we wanted to check the bushings at the back of the radius arms, so we didn't want a load on them. Only time I recall not using the radius arms.

 

[CRF250Rider]

Thanks for all of the help! I just raised the truck using the radius arms in the front and as far back as I could get on the frame before it turns up in the rear. I gave it the shake test when I got the tires off the ground and everything feels solid. I have truck frame adapters on order from Challenger, but honestly the regular pads have ridges on each side anyways so they cradle the frame.

You need to be picking father back on rear of frame

I think I can get there on the passenger side but the driver’s side has a vertical plate bolted to the frame right before the spring perch. I am currently using the tall adapter in the rear to clear the cab steps. Can I stack adapters in the rear to reach the upper frame or how is that accomplished? Thanks!

Yep, get those arms as far out as you can. I will admit there's been plenty of pickups that I will stick the rear arm at the rear most part of the lower section of frame (before it angles up) and been fine. Use your better judgment on that. I usually only do it on short beds that have the original box though. There is a buttload of weight at the front of these diesels to offset the weight of the rear.

CC/LB trucks and can just reach radius arms and high spot of frame. I stack adapters but it's not fun, especially on Ford's because you have to be so damn high to reach the frame and clear the steps. I made extra tall adapters with threaded holes on the bottom and a plate so it will keep the adapter tight in the hole at the end of the lift arm. Also made 'pads' out of C channel so there is a 1" lip on two sides to cradle the frame.....because Ford

Rear spring hanger eye works best

I have a 2015 F350. I need to use double 6" stackers for the rear a single 6" stacker for the front. The rear goes directly under the spring bracket and the front under the radius arm.

ON the rotary 12k symmetrical, I am like the 2 above.......frame cradle adapters on the radius arms up front, and extra stack adapters, stretch those arms as far out as they go, and catch the front leaf spring bracket on the rear. Rock solid!!

Yep perfect situation!

Extended cab long bed diesel yesturday with a vbox full of salt in the back, you couldn’t lift this truck up way you did the 17’ or it would have flipped backwards off the rack. This trucks even in the bay tad crooked as that’s how it came off rollback

 

[CRF250Rider]

I need to get my truck back on there this week and see if I can reach the spring perch both length and height wise. I can definitely see why you had to be farther back on that plow truck! I do plan on purchasing two of the tall jack stands from northerntool shortly. I will place one under the hitch and one up front probably when actually working under the truck (give me a little better feeling about having 8000lbs over my head)

 

[CRF250Rider]

I got under the truck and looked at things. My truck adapters aren’t in from challenger yet but I think they will be perfect for the rear spring perch if I turn them. I put the pad under where I circled originally. I’m thinking of using the new adapters (shown in the left side of the accessory kit) where the arrow is.

Very suitable lifting point

 

[CRF250Rider]

I removed the bracket on the left side frame and my lift arms are just long enough to make it to the ALI front and rear lifting points. I am happy with the lift so far and can easily stand under the truck at full rise. I did buy a couple of two ton support jacks to make me feel better about having 8000lbs over my head.
