Anyone Running Bilstein 5125 Rear Shocks?

I just received Bilstein 5125 Rear Shocks from ToyTec yesterday and scheduled them to be installed at my local Toyota Dealership this morning. I went with the 5125, because they seemed a little more appealing then the 5100's that come with the ToyTec Ultimate Lift and Doug from ToyTec advised me that they would fit properly using the ToyTec rear springs (which I already have installed). After 2 hours at the dealership, the mechanics told me they wouldn't install them without proper written instructions because of a list of fitment issues they had - top bolt of 5125's might be too thick, they didn't come with new bushings for top mounts, the top bolt is too short, etc, etc, etc...:redbrick: As I have no experience in mounting shocks, who was I to argue...ToyTec says they fit, Toyota Techs say they won't.

I searched the forum and found very little on the 5125's (probably my first clue that I should have purchased the 5100's instead). I wanted to know if anyone is running these shocks and/or if anyone could offer any advice with regards to install or possibly an alternative rear shock that will work well with a 3" lift. For the time being, I have $200+ worth of rear shocks weighing down my stock shocks in the back of my truck.

EDIT: Doug from ToyTec has cleared up some of the issues that had the Toyota Techs perplexed. Another example of why ToyTec is first rate when it comes to customer service.

I am still wondering if anyone else is running this shock...

I run the 5125's in the rear. You need an eye-to-stud adapter to install them, which should have come with the shock. Toyota was probably weird about using that adapter. Mine didn't come with busings, or washers, for that matter. I had to go and buy my own washers since the stock ones didn't fit.

But I wouldn't take it back to Toyota, rear shocks are super easy to install.
 

Not trying to be a jerk here...but does anyone who actually have them know which 5125 part number it is? These are universal shocks and come in like 30-40 different sizes, lol.

I've always been curious as to what the actual shock length and stroke are as compared to say the 5100s or 5160s. We can look that up here: http://www.bilsteinus.com/uploads/tx_templavoila/5125_Applications.pdf once someone gives us the part number that's on their shocks :)

I called ToyTec and found this thread. (I know it's from 3rd gen section)

They both referenced 6252.
Which brings up this. (Shows 5100 series though)

But lists part # 33-185590

Great, thanks for calling them and the info! So according to that chart, the 5125s have a total of 8.13" of travel...and I just looked up our 5100s replacement shocks (#33-187174), and they come in at 8.59" of travel. This is what I always suspected that you might actually end up loosing travel due to the loss in height from the eyelet to stud adapter...

That part number you found seems to make sense though, the 5125 length is 21.5" vs the 5100 length of 23.5", gotta leave some room for the adapter I guess?

What do all these numbers mean from a practical standpoint? I have no clue, lol. Not smart enough to understand all this geometry business :tape:

Sorry. It's almost 5:00 on Friday.
 
5125 Series

Hey man, i hope you still check this site. I have blown a right rear 5125 and now i have to replace them...and found this thread. They ride great, i get great flex and they were pretty dope. Only thing i don't have a steel rear bumper, so it needs some more weight in the back.
 
I just (last week) put the OME 891's and Bilstein 5125's from Toytec on my truck and it rides like SHIT! I double checked everything to make sure I didn't forget to reconnect anything, but NOTHING.

Is anyone having problems with their setup?

I'm getting severe speed wobbles, body roll, and when you hit a bump in the road, it's like riding a teeter-totter. I took it to my Yota mechanic, he said the shocks were either blown or too soft (he jumped on the back and it bounced up and down a couple of times).

ARGGGGGG. HELP?!!?!?!
