Well here is some comparison shots to some parts I had laying around off or my OR Xterra (same as the Frontier except the rears might be different?)
The front Coilovers:

The Rear Shocks:

The Rear Lift Shackles:

And I couldn't find my UCA so I'll get that shot tomorrow, But holding it to the truck, man it is huge. I'll also get some shots of other part size comparisons as things are pulled off the truck.
