    KYB AGX adjustable strut install on TD!!!!

    This thread will show you how to install KYB AGX 4-way adjustable struts onto your turbo dodge. As we all know the KONI's were our only option for a quality and adjustable strut but, NO MORE. YOU ARE DOING THIS AT YOUR OWN RISK SO PLEASE BE CAREFUL

    Struts are from the 93-01' Subaru Impreza RS. I got these from TireRack.com for 116.00 each on special plus 7$ shipping. I recommend replacing the strut mount and upper spring perch if your unsure of the condition of your current ones. For this install, I am using the eibach pro-kit but MP springs might be a easier/better fit, i'll address that later. Pictures are worth a thousand words so, here we go!......

    KYB's are RED and factory is BLACK.

    Here are the struts side-by-side. You can clearly see how similar the struts are.





    Here is are the strut bottoms. Same spacing to fit the spindle so no modifications needed here!




    Here are the tops. This is were the first and most important modification need to be made. Stock is on the left.....notice how there is a "lip" after the threads on the KYB strut(right)but not on the stock strut(left)? This needs to filed/lathed down so that the strut mount can slide on. Also, notice how the stock strut goes down about 3/4 of an inch farther? If you keep the KYB strut the lenth it is and just machine down the lip area you won't have a lot of thread engagement. You can lose one of the washers for the strut mount to gain a little back and use a nylon lock nut if you wish. I had my struts lathed down the extra 3/4inch(see pic)so that I could have complete thread engagement and I highly recommend going this route. This is the "hardest" mod and it's not really hard, any reputable maching guy should be able to handle this job.

    Stock on left


    strut mount won't slide on...


    after some dremel work....

    slides on now


    after lathe for extra room...



    Here are the bottoms. This is the second mod, pretty easy. The holes don't line up so you need to make a template from the stock strut and copy it onto the KYB strut. The top hole will be fine but, you need to slot the bottom hole and then reweld. Picture will show better...



    After slotting and rewelding....


    Last thing, We had to adjust the spring seat just a hair for the springs to seat nicely. Just used a wrench and pryed down on the edges of the lower spring seat. The KYB AGX's have a seated area where the spring rest and the stock ones just are a lot wider and flat as you can see in the pictures. As an added measure, we added slots and installed hose clamps just to make sure these things weren't moving, overkill? Maybe, but better safe than sorry!






    Here is the finished product! 4-way adjustable shock from a Subaru. Even better is that these Subaru's have a huge aftermarket! You could buy Koni's for the Subaru or coil-overs and use them instead of the KYB AGX's!!! The possibilities are endless and they won't be getting discontinued anytime soon.





    I have to thank ADAM at HYD rally racing for giving me this info! I can't take credit. I did go a little farther with the lathe and such but, he is responsible for doing this mod years ago!! Thanks Adam!!

    And I have to thank my friend Brian Slowe for doing all the mods, without his lathe and welding modifications skills I wouldn't be sharing this with you all! Thanks Brian!

    yes, thats Adam! His screen name is Rallycsx on the other forum. Please thank him and rate his videos!!

    Struts will be installed tomorrow and I will keep everyone posted on impressions, etc. For the rear struts I will be using bilstien shocks off of a ford ranger pickup. I also got that from Adam. You need to use the bushing from your stock shock on the bilstein and everything else works as is.

    I knew there had to be an adjustable shock/strut set-up out there that would be adaptable to our cars...

    Nice! Other than the bottom hole mod they actually look closer to Daytona struts than than the neon struts do...

    I've been complaining about the lack of AGX for our car for ages. Ive got agx's for other cars sitting in boxes that i try to avoid looking at cuz they just make me jealous. Cheap adjustable yummy!

    This is super awesome for these cars. Cant wait to hear driving impressions!

    Re: KYB AGX adjustable strut install on TD!!!!

    Alright guys, got the struts installed a few days ago. Went pretty easy besides one issue; we used the stock top hole and modified the bottom hole, bolted up fine but once I tried to set the camber I couldn't get it into spec. I was at positive camber on both sides, passenger side was in spec at .4+ camber and left was out of spec at 1.2+. Just need to bring the top hole closer to make it all better. If you do this mod just make sure you use the template from a stock strut to get the spacing right, not only for the holes distance from each other but, also for the holes distance from the strut. Lesson learned.

    Other than that I love the struts! Drove around trying to find the best settings for the street and settled at "2", "3" is a little too hard and "4" is like being in a horse and buggy. I post some more pics when I get a chance.
