SHOCK ADAPTER from Independent 4X

[Joe_Black]

Reg Hinnant had shared some great info he put together a couple years ago when we last had a major shock discussion. Here's what he had...

Hi Joe, I want to share what I have researched on the 7100 shocks. It may save you a little time.
I am basing this on an unlifted VX but I believe you would be concerned with the same collapsed spec's with a 2/3" lift.

Rear shocks
Original VX ext=19.25" col=12.56 eye to eye shock
AK7108R ext=22.29" col=14.06 eye to eye shock
Extended position is approx 3" longer. You may need extended length stop added to prevent rear spring from falling out when fully extended. 2/3" lift may be OK.
Collapsed length is approx 1.5" longer which will be close but should work with our bump stops being the size they are. I have not got under the vehicle to measure this yet.
This shock does not come in a "short body" version that would reduce the col length but the 10/12 &14" does.

Front shocks
Original VX ext=15.35 col=10.24 stem to eye shock
Class 11 front ext=18.58" col=12.00 stem to eye shock
Class 11 rear ext=16.22" col=10.86 eye to eye shock
My measurments show the the class 11 front too long collapsed and it would bottom out before the bump stop would.
I believe the class 11 rear with the adapter possibly would work as long as the rod to eye adapter did not extend the length. I would need to assemble a shock & adapter to know for sure
The part # for the class 11 front is B46-1085R.
The part # for the class 11 rear is B46-0930R.
All of these are the 7100 series with all valve settings available.
They come with reservior & reservior mounting hardware.
Best online price is at jack-it.com & offroadwarehouse.com

Also, Independent4X suggests that you contact them for fitment to your particular application. As they are a Bilstein dealer and do a lot of Isuzu mods that would be good and prudent advice to follow.

Thanks, Joe... Reg seems to be the resident expert as upon further digging I also found this very informative post:

Here is the start of a master list of shock part numbers that most VX'ers would consider.
The big problem with a lot of shocks, that look good, is that the manufactor does not offer them in anything but eye to eye config. (OK for rear but not for front) Nor do they offer them in the correct length, extended to compressed. You can use some additional extended length in the rear. (to the point that the rear springs will fall out at full extension) These variations get into truck lift, etc and personal preferance.

So I'm listing what will be a standard replacement for a stock VX.

This is by no means complete but a starting point for your own research. You can do a search on the forum by shock manuf name & come up with members who have them and comments on them.

Performer IAS Series Shocks for Trooper
“They are different sizes and have different strokes. We do not recommend using our shocks on vehicles they were not designed for as the inertia valve is vehicle specific. Your vehicle has a shorter chassis which makes it lighter -we do not recommend using our shocks as the valves are not calibrated for your vehicle. Please contact Bilstein for a recommendation.”

Specify 9/16" steel sleeves for rear shock or you will get 1/2"

This is an OEM manufacture who will build up custom shocks to order.
(As of this date 7-01-04, Doetsch was not able to build an exact equivalent to the VX shocks. This was determined after shipping a pair of original shocks to them for disassembly & examination. The shocks that they build are much softer than stock.)

No minimum quantity requirements.
Rebuildable by the factory for $35.00 each or by any shop that rebuilds shocks.
All styles of shocks including "In cockpit adjustable type" like the 9000 adjustables.

I already contacted Summit and another retailer and neither of them could help me, but I'll take your advise and contact Independent4x.

I need to replace my shocks and have been searching the forum for what would work best for my specific application. And I haven't been able to come up with a definitive answer so I thought I would ask. I have the OME 912's and will soon be stepping up to 33" tires and lifting another 1". So I see people talking about the Rancho 9000 and the Bilstein 17-series H1 and getting the OEM shocks rebuilt. BUT! What would best control 33" tires for the next 50,000 miles? I want the best handling I can get without skipping a CD at every bump! Thanks for any input...

[UtahVXer]

Why don't you guys like the stock shocks?
Though mine are still going strong, I understand they are also rebuildable upon failure.

[Triathlete]

They are not built to be rebuildable although I believe someone found a place that would tear them down and re-do them. The price to get it done was still fairly expensive and I have heard no reports of anyone going this route or how succesfull it was. New factory shocks are over $400 each. So most are looking for something that performs as well as the stock shocks but at a more reasonable price.

[johnny010]

getting back on topic, did anyone try out the shock adapter kit? what's the verdict? i don't need shocks at this point, but am doing the standard lift w/33" tires.
