I always enjoy threads where I find pictures of my QX4 that I didn't post...

 

Dude, you don't even realize how much inspiration your truck has done for me! I think you have the BADDEST Path/Q on the planet! :aok:

I am wondering if 3 inch sfd would work? I beleive I read earlier that its fine but just make sure before I order all my stuff. And if I do 2 inch spacers do I still need extended brake lines. And how many splines is on the steering shaft? Any help will be great. thanks

Hey Guys,

 

New Here, new to nissans doing my own SFD for the wifes pathy, all ive ever lifted was jeeps and fords before this. just have a quick question.

 

F250 coils?? Are you guys using them in the rear? What year F250 spring is applicable, and how many inches will this net?

 

Thanks

Tom

F-250 coils are too large on the outside diameter of the coil to sit in the top spring perch (From what I read).

 

And for 3"-4" you shouldn't have to extend the front brake lines. I have a 4" SFD, jacked up the front of the truck, to full droop, with no problems to the front brake lines. The REAR on the other hand, had to be extended to something like 30" (with no Sway bar)

now i'm confused. i'm pulling everything together for my sfd hopefully to start this weekend. how are people using f250 coils inthe rear if the perch is too teeny for them?

 

and reading over, the 99-04 f350 2wd shocks are a go with a few extra washers?

 

and the autocad for the shock mounts is now a dead link. i'm gonna have a fab shop make those, can anyone repost the file?

Who is running F250 coils? I've heard of people saying they COULD work, but no-one saying whether or not they work without modification.

 

shift220 is using the 99-04 350 2WD shocks... I went with the ProComp ES-9000's from Summit (PN - 929500)

good point, never actually found someone thats used them. :scratchhead: i guess i'll have to be the first known to actually try :chairfall:

Ok, tried to order some steel today, and got confused on 2 things.

 

The pic/specs of the blocks in the first couple of pages show the blocks as 2.5" x 6".. There's a measurement missing, so I assume that for a 4" SFD that it would be 4"

 

My steel guy says there's no such thing as 2.5" x 4" steel, just 2.5" x 3.5" or 3" x 4", so I ordered the 3"x4".

 

Also, Rod, the pics you sent me show the upper strut spacers as 3" high, but the SFD spacers are 4" is that correct?

 

I would have thought the strut spacers should be 4" as well.

I know there is no 2.5... but DON'T ORDER 3 inch wide tube!!! It won't fit between the pinch weld and the subframe on the front Subframe blocks! Just order all 2x4 and cut them in 6 inch lengths... that way you get thicker walled tube and you don't run into space issues. I did 3" x 4 on the rear.. but most of the tube isn't even touching the "frame".

And yes.. do everything 4" tall. You'll be fine... 2x4x6 and 4" tall (including strut mount flanges) for the strut spacers

Ok, so by what I understand, the measurements listed in the pictures on page 5 are wrong..

 

They show the subframe spacers as 2.5" underneath the pics and 63.5mm in the pictures.

 

From what I understand, they are supposed to be 2"W x 4"H x 6"L (or 50.8mm W x 101.6mm H)

 

So this also throws all the measurements for the bolt holes out of wack.

 

Also, the 4" OD tube for th subframe spacers should be cut at 3.5", with a 1/4" top and bottom plate, that would make it 4" overall height.

The measurements listed on page 5 are not wrong, shift220 used 2.5" x 3.5" tube, cut to be 6" long. The measurement missing in his drawings is the 3.5" tall measurement, which he listed in text.

new4x4r used 2"x4" tube (and also 3"x4" tube), cut to be 6" long, so that's why the confusion...

Ok, well that's where the confusion is, because I got the impression that everyone was talking about a 4" SFD, not a 3.5".

 

Then the spacers listed at 3" + 2x 1/4 in plate top and bottom would also = 3.5" and everything then add's up.

 

 

If someone compiles this thread into more of a "how to" sticky, rather than an "information" sticky, we should try to clairify the differences.

 

Rod's lift at 4" seems to have worked out ok for him, so I'll stick with the 2x4" steel I've ordered, instead of calling my steel supplier and changing my order for a 2nd time.

I just ordered some Rancho RS5000 Shocks for a 2000 F350.... Will these fit or are they to long?

 

I dont know about those, but when I originally put on my lift I thought I was going to have the sfd on as well, and ordered some pro comp es 3000 shocks for the rear. They bolted up just fine, they were for a 2in or maybe even 4in lifted explorer but I had problems with getting my sfd here, so I put them on anyways. They work pretty dang well, except they are just a tad bit long, but id assume that they would be perfet for after I get my sfd on :)

I am going off of this post, it says he is using "99-04 350 2wd shocks"... that being said is it F350 or chevy shocks?

Sorry about the confusion guys. The drawings I posted are for 3.5" tall blocks yes. If you are going with a 4" SFD, then the measurements will be different. I used 2x4 in the front and 3x4 in the back for the kits I made. Muddfildvaynes, how did the blocks fit your Pathfinder in the front?

 

I took down the link because that file didn't fit perfect. Here is an updated CAD file.

 

Here is the plan I used for the 4" rear blocks

The front blocks are exactly the same as the 3.5" lift but only 2" wide with the holes centered.

 

And the rear shocks are from a Ford Superduty

OK, for the confsuion about the blocks being 2.5" wide. No, they don't make them in this measurement. This came from another board member who said these are the size he used for his SFD. He said that he had them custom cut and welded to this size because they fit better, This was only done on his kit. Don't let the 2.5" wide size confuse you. Thank you.

Ok, I've got my head around the blocks...

 

Now I'm onto the brake line..

 

I was at my local speed shop this afternoon, and according to their book, 30" braided brake line IS avaialable, but is NOT D.O.T. approved. The longest dot approved line was 27".

 

Just wondering if anyone who put the 30" lines on is aware of this, (or maybe it was only applicable to their cataloge)

 

I ordered the 27", for the $40 bucks, I can always change it if I need to.

As long as it works its good, DOT.... there are alot of rigs out there who are not up to DOT standards.....

UPDATE* 2000 Ford F350 Shocks will work but you have to replace one of the bushings in order to get them to work because they have a metal sleeve that will not slide over our bolt... I burned mine out with a torch and hit it out with a hammer then let it cool off and a quick clean and hit with WD40 and the new bushing slid in.... Also I went with Ranch RS5000's

The brake lines I had made up were custom made to the length. From what I could tell with the DOT-approved vs non is that the DOT ones have a clear rubber sleeve around the line. The only purpose being for abrasion reasons I guess. Non-DOT lines will work fine.

With the way the MOT is around my towns, I'd rather have it at least have the dot stamp on it.

 

They're pulling plates for e-brakes not working, cracked windshields, everything they can get their hands on.

 

One of my tech's drives a 1993 D21 pickup.

 

The thing looks like a rust bucket, but he keeps it in tip-top mechanical shape. He got pulled over and they escorted him to an inspection station and spent forever just TRYING to find something wrong with his truck...

I got the 35's on! Took it out for the day on Saturday... Everything works awesome! Little underpowered when yanking other vehicles out (when I got traction and the other vehicle was stationary)

Rode nice on the road, no power lost when passing cars. The only down-fall was braking. But other than that, everything works awesome! Very impressed with the truck at this point

I had get longer wheels studs and 1/2" spacers made to stop rubbing the strut. Now I need some serious flares t okeep me from getting pulled over hahaha
