Not sure what truck you have but i believe this is the one.
newera AVR-512.
It needs to be the six wire one.

Sorry, just saw this.
Standard kit, but it was for a HJ61.
It replaced original springs with some old aftermarket shocks. It was shot 10 years ago when i got the truck.
The TT kit was recommended to me by a few people after a lot of looking around.
I also installed new brake hoses with the kit...
