It all depends on what you want done. He can source the powdercoating for the springs also. Elka and other suspension will run around $1500 up last I looked. Jogaca will be much more affordable and be a pillow….
If you have r or se model front shocks, they are 100% worth having done. If you have non-reservoir style, buy some r or se model front shocks off ebay.
Last year I had Yfzr fronts and raptor rear done through jogaca which includes powdercoat, paint, revalve, respring, triple rate springs on front, and shipping for $900 range.
A more standard setup would be closer to $700 if I remember right.
