I searched and didnt have any luck finding the part number or specs for our trucks. I was thinking of replacing my dry rotted, split harsh, stockers with some timbrens. I know they are no replacement for air bumps but they seem to be leaps and bounds a head of factory style.

What specs or part numbers would I want to get if i am going to go with a 3 inch lift?

Edit: this will be for my 87 k5 with 10bolts

I have talked to a couple of guys who have them. Better than stock for sure. Not sure what they used to mount them.
 
subscribed for future reference:waytogo: Ihave the same setup on my burb and want these also. I know theres info in the "Iron Maiden" thread. but he has alot more lift to:dunno: may help though

Did you check their application guide?
I would imagine that with a 3" lift you might have to fabricate your own mount.

I have seen the application guide but I have no clue where to even get the data I would need. I currently do not have the lift on my truck so I was hoping to go by some one elses experience. I know I will need the compressed length to be my final spring stop and I will want some "squish" before the fully compressed length. However, I have no clue what weight or force I will be applying to the bumpstops.

I was thinking of comming up with some way to mount them to the facroty bump stop location as they mount with the single threaded stud that can go into the factory mount hole. I am unsure at this time how I will keep the bumpstop of twisting or getting pushed over. Any advice on how to accomplish this is much appriciatated. :thumb:

I saw iron maiden had some info on them in his thread. I though he went with the s10 bumpstops or something like that?

I saw he also has way more lift. I guess if I could figure out fully compressed length and fully extended length then I could just assume his weight / compression ratings on his bumpstops would work for me?:dunno:

I think i want to put them on all 4 corners. It seems like some people just mount a single up front or a single in the rear.
 
I had them on the front of my old sonoma. Can't remember the part number but when I ordered them I talked to burke spring where I got them and told them about the rig and weights and they recommended the ones I bought.
 
They aren't sold as bump stops and so there is no application listed for use as such. They are air springs. Odds are good that you will have to fabricate mounts. It's possible that with the right amount of lift you might find a model number with the right spring rate that also is about the right length to work with stock mounts, but that would just be lucky. The normal approach is to find one with the right characteristics (call Burke spring with weight on axle, etc. or copycat one of the CK5 members who has already posted part numbers) and then fabricate mounts that put them in the right position for your rig.

You also might prefer to ditch the stock rear bump-stop location, which has the axle tube hit the bump. This is fine for a stock rig with 2" of uptravel, but if you have a lot of articulation, the u-bolt plates might hit the sides of the bumps. The rear spring hangers are outside of the frame, where the front hangers are under the frame, so putting the bumps under the frame has different results front and rear. If you search you will see a lot of good setups.
 
I will see if I can find the part numbers.

You will have to custom mount them.

They are sold as an overload spring, not as a bumpstop.
 
The part #s are in Dave's thread on the Maiden build. I put them on my truck too and have to say I'm very pleased with them.
 
I made mounts from 1 1/2" tube, 1/4" plate and some welded in nuts to make my mounts. I'll see if I can find it in my thread, but it should be fairly close to the end, maybe 15-20 pages back. I'm on my phone though, so no guarantees...

Thats fine. I appriciate the help. My phone wouldnt let me copy and paste. After an update it works fine (android)

I did have to make custom mounts, and also had to figure out suspension compression and set the bumps accordingly. The particular bumps I used compressed to about 1/2 of unloaded height, so with that in mind I set them to leave about 1" of travel left on the shocks.

here is a video of how they work:

I used the A520-75 front and back, I have nothing to compare to, but the work well. No harsh crash at full compression, and I've caught air a few times with them....they are no air bumps and coilovers but a very good upgrade from a rubber or poly factory type bump.
