Outer Limits 4x4 Board

Hey jus upgraded my old 88 75 to a 79ute, wanting around 3-4'' lift n run 315's.

Now iv got a few questions, its got a lift in it (2'' aprox) ironman foamcells up front, ome shocks up back, leaves unknown but seam lifted a bit, dobinson coils front. Nice n comfey but the rear shock is leaking after this weekend.

Whats a good brand coil? I like dobinsons, but keen to see what others run.
Also whats the go with shocks that will handle lots of offroad use, I been lookin at Amanda xtreams.

Any advice greatly apreciated

Also what are profender shocks like?

I've got 3" lift in my 76 with the amadas, can't fault em so far. Put them in with 50kms on it and done almost 30,000 now
