I'm just recounting my experiences (I bought a used truck with the 3" unleveling kit) the headlights were not adjusted at all by the previous owner who added a 3" front lift. The AIM/visibility was made much worse by towing (truck was pointed even more nose high). The 1st time I towed at night (new mexico) with my front bouncing and steering going light over dips and seeing the lights aimed at the stars I decided the leveling kit had to go (up to that point I hadn't looked at the front suspension closely to see there was a spacer kit there).
I didn't realize initially when I purchased the truck the previous owner put the kit on, as I'm used to buying work trucks where people don't do visual only mods. I bought the truck for a job in Colorado, so put it to work immediately after some fluid changes, but up to that point had only driven it during daylight hours. I'm well aware you can re-aim the lights, but I didn't like the ride, the look and towing out of level with 3" of front spacers plus the alignment was never quiet right.
I suspect the leveling installation without a headlight re-aim isn't unique by the number of trucks glaring me. Some people I'm sure do it correctly and re-aim their headlights. But lets be realistic here, spacers are for people who want the cheapest path forward to a visual mod. They're less concerned about the consequences and more about the price. Shop's that install spacers wants to sell the cheapest lift which often means cutting corners with headlight aim, shocks, alignment and etc to keep labor costs down.
My bottom line is there is a lot more downside going to a 3" level from a 2" level on these trucks. I wouldn't bother unless you just love the look.
So I'm new to truck mods. I purchased a 2019 Ram 3500 SRW truck used. It has stock 20" wheels/tires, and I use the truck mostly as a tow vehicle for my company. I noticed when trying to level my vehicle and trailer my truck is nose high. Unloaded the front measure 43" high and the rear is...
