I really like the way the 08 Superduty looks, it's grill, it's mirrors etc and especially the way is sits looking all level and tough. Is it all in the front clip? If you put a 08 front clip on a 99-03 will the older truck sit just like the 08 or is the suspension different?

 

If you install the front clip it shout set as it is know I don't see how it would give the look of it being leveled since the front bumper would still be bolted in the same bolt holes. But it would definitely look awesome! I too like the 08 looks I couldn't justify a whole front clip change so I added the 08 fender emblem to my 02. Remember your truck has leafs on the front and the 08's have coil springs they for sure look like they set higher.

 

Changing the front clip doesnt change how it sits, and doesnt even really change how it LOOKS like it sits, height wise.

Also, an 08 front clip conversion is very extensive, including frame modification.
