Above the emblem is my business logo. I don't believe the lift effects warranty. Just go to friendly dealers. I've only ever had one service mgr mention lifts. And they had new lifted trucks on their lot. I lose 1 mpg.
I used a Revtek 2" spacer in the front. It came off my '16 srw 350. U can use stock shocks, but they suck..... I took the 0-2" Bilsteins off my '16 and they are night and day better than stock. Even with 40k mi on them.
On the rear I put 5" blocks. You'll need special 450 blocks because the spring pins are bigger. I drilled mine out but it was a pain.
I also put on an ICON adj track bar up front. I bought the 2017 style but had to return it for the 2016 style. Wierd that the 350 and 250 have a redesigned steering system but the 450 doesnt.
You could skip the track bar, but it centers the front axle and keeps the geometry stock. Its small but noticable.
Any chance we can get some more pics of those two trucks from the side?
Seems that a few guys are running 245's on the stock wheels. Are there any negatives with running 265s or 285's on the stock rims? Is there any space left between rear duals running the 285's?
