Truck looks good man but, i have heard that whiplash and full throttle suspension kits have major problems with coils sagging. Probly why it doesn't look like you have 16 " of lift. I run 8 " of lift and clear 39.5's just fine. But I do like the chrome. Not over kill but just enough.

Looks like the truck lift was well done. Good job!

 

you should be running 4.88 gears.. You'll be running at about 2k to 2500rpms and going through hub bearings.
Thsi is at high way speeds assuming you have an auto tranny.

the coils look pushed out the sides. Have you tried to flex it yet? They look like they wil buldge out and hit the trac bar bracket

 

nice lookin machine. you need more color on that thing!! IMO drop those mud flaps.

 

oh man tell me about it, the paint job is coming soon, i just cant decide for sure on a color. unfortunatly if i lose the mud flaps I gain a ticket ive got one already and untill the peckernose sherrif that patrols my area retires or moves im screwed.
