Bilstein 5100

Hey guys, I have made up my mind on a 5100 level but I am curious to know if anyone got new coil springs and which ones you got. I am not keeping stock ones. Thank you

 

If you want to replace spings as well, then I would just order a set of complete coilovers. The 5100 are just a hair better over stock. So you'll get a better system pre assembled with better shocks.

 

Question about this...

Previous owner installed 5100's rear, and I plan to have the fronts changed to 5100's as well.

I would like to lift the front a small amount using the 5100's adjustable settings.

The thing is, I know the original springs have some rust on them.

But I would not be able to get the slight lift I want with the stock coilover replacements (shocks and springs), true?

So, am I best off just replacing the shocks with the 5100's and replacing the springs with new ones?

Thanks,

SPP

 

Surface rust on springs will not effect they're action / performance.
Time of use is far more important to look at.
If you were happy with the springs before, just bead blast them to remove any surface rust then if you want, spray em with rust proof paint.

 

5100s are stiff as hell, run away.

 

I have not heard this.

Its true, now you have.

 

Not everyone likes the digressive valving ride/ performance.

 

That's not what I gathered as a new member trying to sift through an overwhelming amount of information.

What would you suggest that would be similar in cost to achieve what I described in my post above?

Thanks,

A little more expensive but much higher quality.

 

Yup if your gonna look at replacing springs, this is definitely the way to go. Wish I would have went Toytec or Falcon over the 5100s.

 

Eibach for both shock and spring.

 

This looks great, and not that much more money.

My only concern is the 2" lift.

I have 5100's in the rear, but not sure what setting they are on.

the rear definitely sits higher than the front of the truck, but I have a Fisher Minute Mount plow up front...

* wouldn't want to end up with the front higher than the rear,

* not sure how high I can go in the front before I have an issue with the plow

* also not looking to create any drivetrain angle issues.

Thoughts? and as always, really appreciate the information and the patience.

Eibach makes an adjustable shock just like Bilstein in which the OEM coil spring is used. And it can me adjusted less than 2’.

I am agree with some of the above posts...the 5100’s can ride very stiff. You’ll notice it a lot when driving down a road that is covered with potholes. Eibach has a much better valving system which softens the initial blows. It makes for a more comfortable and controlled ride on rough rides.

 

5100’s (And all the other kits we are talking about here) don’t have adjustable shocks in the back. They come with no lift, but each allows for some amount of lift via shackles, blocks, or adding a leaf.

If budget is your #1 concern, you can add blocks under your leaf springs that raise the back an inch for very little money! If you want to spend another couple hundred bucks you should look into Firestone air bags.

Easy to install yourself, adjustable so you can have a level truck when not hauling/plowing, but fill up the bags to add rake when you need it.

Geometry issues usually show up at 3” of lift and over.

 

So ... I measured the space between the top of the tire and the bottom of the fender, and the rear is about 4" higher than the front, so I am thinking 2" of lift in the front would be just right.

Thus, the popularity of 6112s for the front.
Installed at 1.9 should do the trick and if your happy with the rear end, leave it alone until it's time to change shocks for the rear.
The setup "for me" with the stuff that I do with my Tundra is 6112s in the front to set up as levelers with better shock performance and the rear is stock with the exception of a pair of Blue Sumo-spring bumpers.
Handles towing my single axle trailer that is enclosed, handles all the crap my boys need moved or taken out to the dumps and handles all the baggage from both their families and my wife's stuff when we do our family trek to Tahoe for a week on the fourth of July.
Fire roads, snow / inclement weather stuff our Tundra is more than capable.
Also as a side note, Running our four grand kids to places when it's my wife (whose a school bus driver for more than 20 years) gives me piece of mind that our brood is safe when in the Tundra.

 

Love my 5100s on all four corners with the front set at top setting utilizing the factory springs. I can definitely see what some are saying about the stiffer ride. However I personally like the way the truck rides with this set up.

 

Lift amounts are approximate -
2" average lift is achieved with coils and setting the shock adjustment on the 1st C-clip setting)
3" average lift is achieved with coils and setting the shock adjustment on the 2nd C-clip setting)
Use of top setting to get more than 3" of lift may cause damage and is not recommended.

With the plow I would use the 3" setting, the 2nd clip.

 

I know the 6112's are in short supply, and are more money...are they that much better than the eibachs?

On Amazon right now, the Eibachs front pair assembled runs just under $600.00.
People say they are more compliant to the small stuff than the 6112s.
If the small stuff is big to you then I would go with the Eibachs.
Both very good at front end leveling.
