    I bought them from Larkspeed but they came direct from Bilstein it seems looking at the packaging and the paperwork. I was going to buy them from Whifbitz but the price difference was over 50 quid per shock, part numbers are the same though.

    Do the shocks have the part number either stamped or on a label on them? Possibly shocks could have been packaged in the wrong box. If not then you may have to contact bilstein or where you bought them from and explain you need to know the size they are supposed to be to check if they are correct

    Yes correct part number is on a sticker on the shock body. Could be the wrong sticker applied to the wrong shock i suppose but the bottom bolt eye to the lower mounting plate is the perfect length when next to the old shocks and its only the piston rod on the Bilsteins thats longer. Ive emailed Bilstein and explained the problem so hopefully will get a reply in the morning, if not ill phone them.

    The spring doesn't move when its seated in the lower support and decompressed so surely this can only happen if you actually have shortened/lowered spring and not the OEM spring. There are no specs I could find on the OEM spring other than ship weight of 3.08kg so if you take your spring off you can at least check its weight against the OE one.

    As you can see, not only is the rod longer, the bottom seat is also slightly lower.

    I'll put a spring on and take a pic of the problem.

    The springs are deffo original Toyota springs. I even have a spare spring not off this car and they are all the same size

    Heres with the spring on. I can remove the top mount with no spring compressors and with everything bolted together the spring can be turned on the shock easily and rattles around

    Turned the base by hand


    You can see that the spring is exerting no pressure on the mounts

    The lower Spring seat being lower than the standard shock seems odd, I'm away from the spare shocks right now but will measure asap for you.
    Number 8 ...........doing my best to keep
    Number 9 ........been and gone!
    Number 10 ........on its way

    Thanks Scooter. The whole thing is so strange but you can clearly see how the difference between the length of piston rod and the slightly lower spring seat is causing the problem. This has got to now be a manufacturing defect at Bilsteins end. I highly doubt all 3 of my springs are oddball especially since one came from another car.

    And now another problem. I just tried to put the car in the garage and it scraped like hell. The front end is a good fingers width lower each side than standard. I could get 3 fingers between the top of the wheel and arch with standard shocks and have a bit of movement. Now I can only just manage to get 2 fingers in! Obviously the lower spring seat has lowered the car.

    Just a thought, are all OEM springs the same? A quick look on toyodiy and I've found at least 3 "EDIT:4" different part numbers between models. Maybe springs for kyb shocks are different to those for OEM bilsteins?

    Toyota part numbers:
    48131-1D561
    48131-1D582
    48131-1D601
    48131-1D602
