Bumpstop's and front bumpstop extension

Found out i need some bump stop extensions for the height of my icon's and figured I might as well upgrade the entire bump stop at the same time. What's everyone like for front bumps? what about the rear? Worth doing or should i bite the bullet and get the icon rear hydraulic kit (which Ill never use to its full potential).

 

Everyone seems to like durobumps. What I'm about to purchase for mine

 

Can you please elaborate a little more?

What about the Icon coilovers require a drop in the bump? I see Icons bring run by a lot of people, haven't seen them shim the bumps though.

The lift height should not affect your bump, the coilover dimensions affect this. The compressed total length would play factor to this.

Or, unless you swapped out springs for a longer length - then a shim would be needed to prevent coil bind.

Edit:
So, after thinking about it....I get it, now it makes sense. Your block height changes as you add preload which is why they tell you not to preload past 2" of threads. Basically shaft is fully in the shock body when the block height is reached with 2" of preload.

 

I used the Durobumps on the front, ICON on the rear. Very happy with them both.

icon sells a bump stop extension kit, it is recommended if your coil overs have over 2in of thread showing. Mine are at 2 1/4.

 

Link?

All I see are shim kits for Raptors.

Where is this recommendation noted?
Nvm, found where they tell you simply not to preload past 2" of thread, doesn't mention a shim.

Wheelers offroad sells bump shims or you can just install a washer in there. Bilstein provides simple washers with their 5100s.

 

@Coachbuilder1 sells some great ones for a good price. We’re talking fronts, eh? I have them and like them.

 

What do you have in the front for lift?

 

6112 set at 1.9 and 1 inch of shims. Total lift is 3” but I used shims and that’s an automatic bumpstop extension. Not sure if you need them but if you do, the coachbuilder ones are quality and easy to install.

 

I have 5100s all the way around. The front is at top setting. I want to add (1) CB shim on front passenger side and (2) shims on driver's side. Do I need bump stops?

 

Wheelers bump stops up front for me, total chaos and king in the rear.

 

Is that how close your rear bumpstop is at ride height?

 

bed is loaded with about 1200 pounds in that picture

 

I was gonna say that looks rough.

 

I build my own!

 

Is the CV Axel boot that stretched or is that designed so the creases don’t contact each other?

 

I actually pulled them out a little when I installed the new axles to prevent rubbing,the dimples are just from me leaning on them and they will pop out!

 

+1 for the wheelers front bump stops. Currently on a 2” leveling kit and by far they have been 100% more noticeable when going over large bumps. I feel like pictures don’t do justice to the size of the wheelers ones so I’ll leave this here for comparison.

 

Your 5100s came with a shim that should have been installed to space your factory bump stop lower, they provide it because of coil block height issues when fully compressed.

As far as running an aftermarket bump stop, that is all personal preference but you don't need to. They compress to the same height as OE.

 

I don't know if the shop installed these shims. How can I tell?

 

Look at the bump, is there a washer between it and the frame? If so, it's there. If not, then no.

 

I'll check it out when I get home. Thank you for your time.

 

No problemo, if you can't tell just post a pic

 

One thing to consider when changing to aftermarket bumps.
Since most aftermarket (duros /superbumps / timbrens) engage sooner (Taller compared to OEM)to progressively dampen a full bottom-out condition, they take away the advantage of high end coilover adjust-ability
while more is typically better, the bump stops can start contacting the LCA after a 1-2in of suspension travel depending on if the truck is lifted or not.
Once contact is made the bumpstops abosorb energy and take it away from the coilover. This can be good or bad.
If you are bashing your truck and using the full suspension travel all the way to the OEM bumps then upgraded bumps are a good idea.
If you spent money on a good set of coilovers for overall ride improvement with no to minor lift, then you likely won't get to enjoy the fully ride benefits of the coilover because the bumpstop take over first.
While the most expensive option, Hydro-bump stops are the best way to go because they can be infinitely adjustable. ( travel/ pressure/initial contact can be adjusted per application)

 

@DexterL

Why are you needing so much preload?

Instead of preloading over the recommended threading, why not jump up a coil spring rate?

 

Are you running a 6 inch lift with these bump stops? Like this set up!

 

I used wheeler super bumps front and rear. With my icon lift. Also I have 2” of thread and 1.75” of thread showing. No spacers. Gave me just under 3” of lift

 

Yes, 6 inch with CB shackles and OME springs

 

Rear, sumo springs, 1 full set full time ,1 set cut down to bump stop for when axle articulation is needed. Swap in minutes with the hi lift.

 

Perfect as I’m running the same set up! Did you install the rear bump stops yourself?
