Bilstein 5100's installed

Postby slow_90firebird » Wed Jun 08, 2011 9:07 pm

Well my new shocks showed up today in the mail from AJ usa. So like anytime I get new parts for a truck, I couldnt wait to put them in.

The part numbers used were

33-186542 Front
33-185569 Rear

if you are all stock suspension, and dont plan on ever lifting or leveling your truck, you might consider the 33-185590 for the fronts, as they will be the closest match to OE replacements... the ones I got will leave me a little room to level the truck in the future if I want, but still fit in there stock because of how close the bumpstops are they wont bottom out.

Now, if I knew how much of a pain these were gonna be to install, I wouldnt have been so excited to install them. These shocks are fricking tight!!! The rears were longer and came with green straps to keep them somewhat compressed in the box. The fronts bring shorter, fit in the box fully extended.

The first thing you will notice is the apparent quality. If you are used to parts store shocks, or cheap lift shocks, you can appreciate what I mean. The machined finish looks great, and they came with the boots installed already. And they have the apparence of quality, not the cheap spraypainted look.

I think I already said it, but these shocks are tight. Im a pretty small guy so it took all my weight to compress them. This is what makes them hardest to install. On the rears, you need to use 2 of the metal sleeves included in the upper bushings. Then I bolted the tops into the frame and started the nuts. Now, with the green strap still on, I couldnt get them compressed the 1/4" i needed to slide them on to save my life! After much sweat and cursing, i had to have my dad come out and jump on the hitch to get the shocks onto the lower studs. Make sure to grease the bushings those fit really snug too.

The fronts were no better. The bushings on these shocks are a little different, they fit but not very easily. The best way I found was with a hammer and a socket, so you dont mar the threads. I Started the bottoms first and then and to use every last ounce of myself to compress them under the truck and swing them up. The top bushings were a huge PITA. I had to hammer for a while just to get them on enough to start the nuts. Again, grease is key.

I took the truck around town tonight and noticed a decent improvement. The rear actually rides beautifully, and the front is still very stiff, but much more controlled. They helped alot with the bouncy bounce over bumps. I would say they were worth the price paid. I will have to report back again though after I ride on them a while, and go to work with them. I think this is probably as good as it gets for these worn out stock front springs.

The shocks I took out were in pretty sorry shape. The rears both still rebounded out, but very weakly and they made fluid noise while doing it. Those are god knows how old monroes from the previous owner. The fronts I just put in last fall, and only one still rebounded out. And very slowly and choppy. It took very little effort to compress. The other took almost no effort to compress or extend, and then it just stayed where it was. This probably contributed to the harsh bouncy ride.

Here are some pics:

So they're THAT stiff :shock:
Now I'm beginning to second guess my decision to buy them...
I think my biggest problem is the stiff springs, I really hope it doesn't get even worse with the Bilsteins... :?
Well, I guess I'll just have to try and see

I think you will like them after they are installed and driving around... you might have second thoughts during the install tho.

But you do have that tractor though and that will make it way easier for you. So will having the front end lifted a little. I did them in the driveway with all 4 wheels on the ground.

Please keep us updated. I have heard a few people say the bilsteins are too stiff but i wonder what they would be like with some aftermarket soft springs? I am thinking about going this way.

Ok, now I've installed mine too.
And I see what you meant with the hard install :shock:
I think the bushings actually are the wrong size for our trucks...
Since the sleeves that goes in the top rear bushings are much smaller
than the studs we have to pry them on in every other mounting point :?

But I finally came up with a way that wasn't so hard.
First I removed the bushings from the springs.
Then I chamfered the inner diameter of the bushing with a knive, on the end that goes on the stud first.
Then I pushed the bushing halfway on to the stud, before I pressed to shock loop over it.
And don't forget a lot of soap for lubrication.

There was a noticeble difference in handling compared to the old Skyjacker nitro shocks
(they where only about 1 year old, so they weren't worn out)
But not as much as I had hoped for...
But I guess it's my really stiff lift springs thats the real culprit (don't know what brand they are)

I have actually started thinking about installing longer springs to get a softer ride.
I've done it with my K30, but that was mostly for the flex.
I'm thinking a 52" rear springs from a chevy would be nice in the front :grin:

Well I'm glad you at least like them better than the skyjackers.

I bet my springs ride worse than yours. Usually the lift springs get a little softer the higher you go, as there is more room before you bottom out. I had someone I work with that weighs 350lb try and jump up and down on the front bumper, and he couldn't move it even 1/4".

I don't think you could fit much longer springs under the front without making the frame longer past the bumper. But I wonder what would happen if you put 4" or 6" lift springs from a gasser and let the diesel sag them?

so i have i was tired of hitting the bump stops on my truck everytime i hit a bump. (and tired of having the dates complain about it to ). so i found deaver springs that made me a set of custom springs for the front and rear. the front 11 leafs for the front with a 3 inch lift. and the rears are 12 leafs but 9 were wear the spring and than 3 for the over load. and also i had the rears extended i think about 3 inches for better ride, and more to flex.
i also had deaver spring get me a set of 4 custom 5125 bilstien shocks that were set up for my w350 with a 3 inch lift kit
and i also had to get a extended brake lines, so i bought a 2 stainless steel braided lines made by skyjacker, these are the ones that go to the axles not the caliper. (i cant seem to find the ones that go to to the calipers so i will have those ones custom made by someone (im up for sugestions let me now on a stainless steel company))
so i will get to my point is when i get my lift kit on i will let you now how much better my truck rides with spring and shocks.
but i have to finish this first gen bronco first, and than i have to put the steering box and pump back in my k5 blazer so i can drive that well i put the lift kit on the dodge.
if you want pictures or questions let me now

Sounds really interesting, I'm looking forward to hear how it works.
Do you have any pics of the spring packs?

I'll only have to move the front spring hangers about 2" forward to fit 52" springs,
if I wanna keep the axle in it's stock location.
So I think it's possible without interfering too much with the bumper.
And I've got a tube bumper anyway, so I could always adjust it some.

Wow, that's a lot of leaves :shock:
But on the other hand the leaves are pretty thin aren't they?
Is it supposed to be softer than regular lift-springs?

ya it thinner so it can ride a lot better, but it has a lot of springs so it can carry as much weight as stock or more. that is why i went with deaver for spring casue they made the effort to meet those specifications when they made the springs

Im interested too, to see how they work for you.

I would only want front springs though, if you dont mind me asking, how much did those springs run you? Or specifically just the fronts... I am prefectly OK with the ones in the rear, they ride ok and not too many leaves, i believe they have been changed by the PO, because when I had this guy change my spring hangers he said none of the bolts were siezed in the bushings (as would be expected after 17 years) and there was still some anti-sieze grease on the bolts.

The fronts, on the other hand, I am sure are origional. Those ones are all rusty and have grooves worn in them where the leafs rub together.

I think I have to revise my first impressions.
The Bilsteins are a LOT better!
I think I over analyzed the handling when I first tested them.
Now I've realized that on dirt roads that I've completely avoided with the dodge earlier cause of the rough ride,
I now drive with full throttle :mrgreen:

I guess stiff springs needs stiff shocks to dampen the bounce...
