You did the 2-1/2" front and 2" back so the overall effect was raising the front 1/2" over the stock setting so in effect the front is higher in relationship to the stock front to back relationship, if that makes sense. You are of course right the center line is now 2-1/2" higher. I'll curious to see what you think after you've had a chance to drive it.
You're right I was just thinking about that after I replied. So driving tonight I didn't notice any difference with the headlights (no angry oncoming motorists flashing their high beams at my low beams)
Ride quality IMO is improved. You definitely feel higher and the step into the truck is noticeably higher even with the power running boards. Stock handling was not bad, but this kit just makes it feel a little more "floaty" which is just fine by me.
A few other things, definitely will need to move the rear brake lines down about 1.5" put the spacer on and let the rear go full extension and the OEM placement of the rear brakes had the lines screamin'! 5/16" drill bit made a hole that held the OEM screw in just fine.
On our models, the rear inner top strut mount bolt is very difficult to reach on the driver side due to a fuel line in the way and extremely difficult to reach on passenger side due to the exhaust pipes. Barely enough room to get the wrench back there to loosen which took roughly 5 minutes per side as I only had standard wrenches for this part. Will also need to remove spare tire to break the rear LCA bolts loose.
Highly recommend DC'ing the battery to avoid messing with the EPAS like I said before.
Overall I am extremely happy with how it turned out and can't wait to get some new rubber under her later this year!
