part numbers or specs would be appreciated.
also- what tire size is max and good all terrain?

I don't recall having those options when I got my struts. I assume any of them will work.
I fabbed the strut mounting plates to simplify the next strut replacement. It is absolutely not necessary to the project. I made that point perfectly clear in the original write up.
My opinions about tire sizes are also well stated in the original write up. I am on my second set of 215/85R15 tires. I have no relevant opinion about tire brands or tread patterns.

It's been 6 or 7 years and 30K miles since the lift. I recently replaced both front half-shafts because that was cheaper than replacing just the torn boots. The CV joints themselves were fine.
I don't believe the boot failures were exacerbated by the lift. And, FWIW, I was able to R&R the half-shafts without removing the wheels or disassembling the hubs and steering knuckles.

Lastly, I still haven't found a good solution to the rear shock problem. I am currently running some units that have the correct upside-down mount configuration and are a couple inches longer than stock, but they will top out at full droop.

1965 mustang, 6 cyl shocks have a stud on each one.
my Previa has an eyelet on top. Anyone know what rear shocks work?
Going with AWD struts- hope they work.

KYB 343131, but you have to remove the "dog bone" from the upper eyelet. Not an easy task. You'll probably need to reuse the rubber bushings from your old shocks.

Just found this out for rear-
98 Tacoma 2 wheel drive
ordered gas adjust today.
Ordering TRW struts- can’t find anything good.

I bet this is my car, but this photo was probably taken when the previous owner had it. It looks just about the same just a rack on the back now. It does have a dent on the tailgate.

For a second I thought that could have been my new van but then I looked at the date...lol

Mine and yours are almost twins. I also just camperized this one, my third Previa, here's the YouTube tour link: https://youtu.be/W_HXFEsSquM

I bought this one from Samay last year, dual sunroof, 4WD, lifted unicorn with JDM lights. If anyone is wondering, wheels are 15" with +6 offset (I wanted -6 but couldn't find these in stock) with 215/75/15 AT tires. The wheels dropped by MPG by about 1-2.

I have a 94 LE Alltrac n/a. Did the 2" lift with sienna struts, mustang springs, and added threads to kyb rear shocks.

Just yesterday I felt something different when I pulled into my parking spot. Got out and saw that my rear left shock was broken right at the coupler for the allthread.

Now I'm searching all the different options for replacements without having to modify the threads to get the correct length so they don't clunk over bumps, and also have that weak point where it broke.

Do these shocks with the dogbone in the eyelit work well? Can i cut and press that dogbone out and use bushings? They seem to have over an inch more extension and about the same compression as the stock Monroe.

I just ordered some stock Monroe from oreilly to put on the van to get me by until I figure out the best solution.

This really is a horrible mounting design for the rear shocks. They sit so low and close to the ground where rocks and curbs can reach them. The angles on the bottom seem off and looks like it puts unnecessary strain on the shocks.
What do you think? Is there any good solution to this?
Attachment 12425

This isn't a good suggestion honestly, but I have wondered errantly if one could flip the axle so everything would sit on top.

I don't know where you would get the range of motion though. Seems like youd have to put strut towers inside the rear of the van body.

I've been running the KYBs for a couple or three years now. After removing the dog bones and installing steel bushings the mounting works well. Overall the best solution I've found for what should be a simple problem.

What steel bushings did you get?

Been a while, but I think I just used the bushings from the old shocks. Or I might have found some in my drawer of shock grommets and bushings.

As a bonus, the springs should be stiffer than the Previa because of the Sienna's front engine configuration.

Has anyone confirmed the strut top bolt pattern, and/or fitted complete sienna assemblys?

My dream lift like this so that I don’t have to use a jack anymore

You'll just need a much larger one. :)

What are the groups thoughts on doing the Sienna strut/spring assembly swap in the front and using the Journeys Offroad lift parts in the rear? It seems like that might give equal lift in the front and the back, and avoid the rear strut issues. I realize this would waste some money for the Journey's front parts I would not use.

Thoughts?

My proposed parts list would be:

1. Journeys offroad kit - $385
2. Bilstein rear shocks B6 4600 - $170
3. Front KYB SR4177 and KYB SR4178 - $300

I think that combo should get me all the parts i need and com in at $855 plus shipping and any services related to the front knuckles.
