Has any one else had this problem of the front coil springs dropping out and how did you fix it.

Probably a too long shock, or a too short spring.

This was a 3 inch lift kit from superior engineering,I asked for a 3 inch leagal lift kit that they would certifie and these were the shocked they recommend and supplied in the kit

Your springs are too heavy. Even in the pic those Dobinsons look like they have a large diameter wire. You'd hardly be compressing them with the weight of the vehicle

That makes better sense, if it was bought as a kit. Get the springs and shocks part numbers and contact superior engineering. Maybe they supplied a wrong product.
The 2" lift that was in my RB30 Patrol was meant for a TB42 which is way heavier, and was almost like a 2 1/2" -3" lift.

It's more likely a spring selection issue, as with a vast, vast majority of spring purchases.

This has turned in to a nightmare I asked for a quote from superior for a legal 3 inch lift to get certified, the spring numbers match up with the paper work, I have contacted superior and they said that now the shocks are to long that I have to sell them and buy shorter ones from them what a scam, they apparently have changed there minds since selling the kit, they want me to go from a 5 inch shock to a 3 inch shock to keep the spring compressed.

I will double check again but they sent me a constant rate spring of 50 kg to 100 kg and I have a steel winch bar with a winch on it I have not gotten around to putting the spoties on yet, the first time I got my front springs from superior they were for a Landcruiser not even the right brand.

They sold you gear that was not fit for purpose.

You need to measure the wire diameter and the free height of the spring and cross reference that with the info on the website to see what you've been given

Something very wrong with this info. You cannot have a constant spring rate with 2 values. Second, if it does have 2 values, its a variable spring design. Without a spring diameter given. your coils look very heavy. Superior have sold you a matched set-up, so if it isn't what they defined, send it back. The coil length simply looks like a coil for a different vehicle. This happened to me when the coils were swapped out by the engine conversion guys in WA. I ended up checking the part number and they were for a Pajero of all things - to this day there is no explanation as to how this happened, however the supplier paid for the new coils.
For comparison, and bear in mind my vehicle is a lot different to your, but a 70kg constant rate 40mm nominal lift coil had mine looking like a magna. I punched a hole thru the sump the ride was so mis-matched. I took it to a well known supplier and they spent 2 hrs swapping coils out to get the right height and compression rate. I ended up with 110kg constant rate coils, nominally 75mm in the front. The rears are 400kg constant rate 75mm lift with boss airbags - this combo works for my vehicle.
My advice is simply to state the obvious to the supplier and get them to sort it out.
