  View original topic: More travel out of FRONT SHOCKS?? Page: 1, 2, 3, 4  Next

My van sits high and the front shocks are close to topping out.

I have Bilstein HD's and want the Koni's to get a little firmer.

So the Koni's are shorter than the Bilstein's so it is a no go unless there is a way to extend the travel.

Thanks Jeff

If you have a now stock front ride height you are probably going to need a non stock shock. You will just have to get out a catalog and see what is available.

How high do you sit?

I am at 18.5 and the crappy KYBs fit fine in the front.

I have read, recently, the the Konis may be too short.

I find this hard to believel

Guess some comparisons need to be made.

I would love to put Koni shocks in the front, as I am not happy with the KYB.

I have Bilstein HD that have 14.98 and the Koni's are around 14.5.

My van sits at 19".

jrobewesty,

Excuse my ignorance, but how do you know the shocks are close to any limit? Is that on compression or extension? I am a bit confused. Stock on the 85 was pretty high at 18.5 and the standard shocks which these aftermarket ones are supposed to replace should not have much issue with your extra half an inch. So I want to know how you figger this is an issue?

I made the switch from Bilstein to Koni and didn't see any appreciable difference in extended length when I compared the two. If you're liable to top out with the Konis, then you'll do the same with Bilsteins.

Its from a post I put up after i couldn't get the koni's to fit with the GW springs. Billstiens did & I do like them, the koni's were sooo sweet tho!

How did they not fit? What did you do to determine this? Usually a half an inch for a shock is not that much of a deal. We are all VERY curious.

The brick and mortar part of Shox.com is a short drive from my house. I want to go there and buy some new front shocks. I REALLY like the Konis, but do not want to be playing musical shocks.

BlackDogVan Wed Jun 10, 2009 1:04 pm

The shocks reached full extension before the suspension did. Drive off a curb or a big speed bump & the sound it makes will NOT warm your heart. My koni rears seemed to be better off but after topping out the suspension too much one has blown its seal. Koni's measure out a little more than .5" shorter.

Hey there are lots of members here running GW lift on a 2wd, anyone have success installing the Koni's???

I'm not getting up on a soap box saying i'm super-duper right, just sharing my experience.

r39o Wed Jun 10, 2009 2:51 pm

UNDERSTAND.

Maybe they have a longer shock available? That will be a good question for the guys at Shox, then.

Thanks,
Walt....

And uhm, just to drive the point home, don't forget that the shocks are mounted inboard of the ball joint centerline. This means that 0.5" of shock travel becomes 0.82" of travel at the ball joint.

JeffRobenolt Wed Jun 10, 2009 7:15 pm

At 19" my Bilstein's are close to the limit. They aren't hammering when they top out but you can feel them just reach there limit through the gas pedal on some bumps.

My rears hammered when they topped out. I ended up using Chevy Astro Van shocks.

I think I might try these extender's. They say they are 12mmx1 and fit Bilstein's.

Does anyone know the thread size of the Koni's. I rather get some stiffer shock like the Koni's.

JeffRobenolt Wed Jun 10, 2009 8:17 pm

I did call Koni and Bilstein tech departments and told them of my problem.

I asked if they had another shock that was a little longer and they both told me they can only look them up by vehicle application.

So if anyone has a catalog that shows specs please chime in.

I did order the 1 1/4 extenders for my Bilsteins.

Can anyone with a set of koni's check the thread size?

Thanks Jeff

1621 Wed Jun 10, 2009 8:49 pm

IIRC the thread sizes are different. I think the Bilsteins had a finer thread pitch. Sold my Bilsteins to another Samba member, so I can't compare.

Search around through Tristar Eric's old posts. I think he modified some shocks to gain some extended length and included photos and instructions.

Another way.

Sorry, no photo of the front configuration...digicam on the fritz. Will post shot when it or a replacement allows it.

Monroe Sensa-Trac load adjuster #58253 is second from the top, left column, page 15...compressed length: 10.5", extended length: 16.125".

Rockauto's got em for $58/pair...search under part: 58253, manufacturer: Monroe, type: suspension, shock absorber.

Killer performance:cost ratio IMO.

BTW, riceye had pointed out some time ago that #58275 may work well for a non-lifted van...my experience with it's longer brother strongly suggests that it would indeed be excellent in that application....also at a killer performance:cost ratio.

Konis = M10x1.0

Look close at the catalog. Those two shocks have different mountings and helper springs. One pair will likely not work. Plus the helper springs may mess things up. Maybe there is abother Monroe that will do the trick?

Whoops...thanks Walt...s'what I get for going off of memory...I've changed the post to reflect the correct non-lifted vanagon part #.

snoop Thu Jun 11, 2009 6:49 am

Here's a pic of the model I'm using...the 58275 has the same mounts.


Note: one does need to use collars or washers to center the lower shock mount in the lower control arm. There are several ways to optimize the top mount...easiest is to use a golf weight ring which nestles into the top of the shock housing and the bottom of the shock tower cup perfectly...they do come in colors other than pink...

JeffRobenolt Sat Jun 13, 2009 9:24 am

The Monroe pfd catalog is a lot of help but I ran into a problem.
The stock front shock part # for our vans is 34970.
It shows a mounting # of S4 for the top and bottom which can't be right.
The S4 is the stud.

Is there any other shock vender that has a spec sheet like monroe's to compare?

Snoop, the model you are using has a LS38 bottom mount, I could go that route and shim but it would be nice to find a bolt on.

Thanks Jeff
