I have that exactly setup 08+ 4x4 coils, 5100's in the middle setting. Zero coil bucket contact. I tried a .85 spacer (PRG 1 1/2 level kit) and I did get contact but like NorCal said that happens on some but not all Titan's.
I wasn't really trying to level my truck I wanted more room in the front wheel well. I think I ended up with about 2 1/2 inches of lift which actually had my front end slightly higher than the back on level ground. I installed a 1" spacer in the rear to get the back end slightly higher. Here is a picture leveled before the spacer in the rear. The front tire is sitting on a storm grate so it is hard to see but the front end was higher than the rear. I would say it is a safe bet that the setup will get your truck perfectly level at the least. Make sure you go with the 08 4x4 coil (part# 54010-ZR40A) and not the stiffer pro-4x (part#54010-ZR41A).Is the truck pretty level after doing this??
In theory should gain 1 1/2 inches of lift with 08 coils and 5100's not using the level rings. The shock is 1/2 longer than stock and the 08 4x4 coils are 15" long uncompressed compared to the 04-07 4x4 coils which are 14" long.so I wonder how it would look with the 08+ coils and the 5100's at the lowest setting??
