just fitted double adjustable shocks. Arrived with spring rest plate and adjustable plate to sit spring on and adjust same .
question? how do I lock adjust plate from screwing loose.

should have a small grub screw in the rotating plate.

If you mean the two halves of the spring platform you just do one up against the other

They don't unscrew on their own, well mine don't

Alex the weight of the car will keep them locked in place no need for anything else

Hi

As said they do not move when they are preloaded with spring pressure. However if you a situation where the spring has no preload during droop travel they will sometimes move small amounts. Which is why i offer the option of having a grub screw fitted when ordered from myself.

Other notes, are you fitting them to the front of a Indy R. If so have you had the needle valve changed and valving set to suit. If not you will retain the same basic problem as the single adjustables have.

Cheers Matt

No grub screws on the shocks. If I put a ziptie tight against base of adjuster plate once final setting achived might keep in place.
