Question about adding sasquatch suspension to non sas

IL21Bronco

For all the suspension experts out there, what harm would be done if I swap my Non Sasquatch Black diamond suspension with a Base model Sasquatch Suspension? I know the spring numbers are different with sas base vs sas black diamond but would there be any real noticable difference driving on the suspension that came off a base sasquatch? Like if someone has a base sasquatch and adds an off road front bumper would they then need to change the springs?

My first Bronco I purchased was a non-SAS 4 door Black Diamond 2.7. I purchased take off SAS SUSPENSION from a 4 door First Edition. I had 4 wheel parts install it, It turned out great and performed very well. I had some concerns prior since the first edition is probably a little bit heavier with the added features like leather seats, Sway bar etc I had no problems as far as driving dynamics. I will say the MPG did go down on my Black Diamond once I installed the SAS suspension and SAS wheels/tires. Overall it’s a great modification and it looks great.

The only this I can say about your concern adding a aftermarket bumper etc. I think the spring rates are marginal between same engine size. I could be wrong buts that something I would compare as well.

Im hardly an expert but I put 4 door first edition suspension on my 2dr non sas black diamond and no difference at all. Just make sure to immediately get an alignment

Thanks for the reply. Yea both cars have the 2.3L so I figured that there is probably very minimal difference in spring rate but the fact Ford has all different part numbers depending on if you have 2.3, 2.7, tow or non tow worried me lol I guess I can always throw it on, get an alignment and then see how it feels and if the ride is horrible I can buy the proper springs for BD 2 door sas

Yeah you shouldn’t have an issue.

If you were taking 4-door Badlands (heaviest trim) suspension and sticking in on a 2-door Big Bend (lightest trim) I would say your spring rate is going to going to be way too high and it’ll feel super stiff. But Black Diamond 2-door is fairly middle of the road with the steel bumpers and bash plates and should be in the same general ballpark as a Base with Sasquatch.

If you tow near the weight limit at some point in the future you may want to take it easy at first. The short wheel base combined with mis-matched springs may lead to some added vehicle instability/dynamics issues. But otherwise I think you’ll be fine.

And if it ends up being an issue you can always find a VIN of a 2-door Sasquatch Black Diamond and use that to find/order the correct springs at a dealer.

A 200 dollar perch kit is cheaper and works better. You all realize the sasquatch suspension has less travel then the non-sasquatch Bilstein suspension does right?

I swapped my sasquatch off for a badlands suspension with a perch collar, same ride height, more flex.

If you goal is to go up to a larger tire, body lift, perch collar, cut the front crash bar mount. (And maybe think about some steering bronc buster components if you are going to off-road with it.) With IFS you want to avoid the spacer lift at all cost.

"I would say your spring rate is going to going to be way too high and it’ll feel super stiff."

Both Bilstein suspension springs are the same fyi. 2 door and 4 door are the same part number.

The Hitachi springs should NEVER be used with the Bilsteins.....

Part numbers for the springs...

• Front: MB3Z-5310-xx
• Rear: MB3Z-5560-xx

xx = is a 1-2 character code that corresponds to the different variants. There is a dozen or so different springs.

Depends on your usage. I wouldn't use a spacer personally but if I was using it as a daily driver or mall crawler (which I'm not knocking) I wouldn't see why it would hurt. And I'm not sure I'd say cheaper. Plus no compressing of the springs for install on a spacer.

Yes and no. Same number with different letters denoting two or four door, engine, and tow package or not. From 6g:

I think you meant that sas has less travel than non sas which is true. A little under half an inch. But then again sas has the same half inch height difference over badlands. Just all depends on what you're looking for. If you want big flex for rock crawling you might be looking at upgrading over stock parts anyways.

Thanks, fixed the typo.

I was referring to the set, you physically cannot swap front and back springs, they are drastically different.

It's more then just the half inch difference in ride height, the bump stops are shorter as well.

Perch collars are NOT spacers. It's inside the travel of the coilover. You can certainly go to far and get spring bind and bottom out issues, but the Bilsteins are pretty long imo.

Spring spacers are similar but this truck is pretty heavy for those.

Bottom/top spacers are a big no for me, like half inch or less for levelling is fine, over that you start impacting things in a negative way.

For example, say I put in 3+ inch spacers to fit 37s or 40s. On the rear, I am probably fine, it's not going to travel as much but it's a straight axle.

On the front, oh boy.
3 inch of spacer lift removes nearly all down travel. Now you stuff a 37 or 40 in there, assuming you keep the fender the same, you have no room for up travel. So you gained an inch, or 2.5 inches in lift with the tires but lost nearly all articulation to do so.

TLDR To each their own, but I think the Bronco performs better at 35 inch tires with the non sasquatch Bilsteins and some minor adjustments. If someone throws long travel or portals, sure that's going to help, but you can buy a second bronco with that much cash.

If you’re going to upgrade the suspension, might as well go all the way and install some aftermarket shocks, springs, control arms etc. going to get a lot more for your buck.
