Truck Bed Height

I have a 2018 RAM 2500 4x4 that I use to pull my fifth wheel. Great truck but it sits too high. Has anyone modified the OEM springs or replaced them to lower the bed height. I need to lower it at least 2", but would like 4" front/back.

Thanks for any input you have.

I lowered my 4x4.....took spacers out of the rear leaves and had new coils made for the front......and don't have a bit of drivetrain problems other say you will have.....bed floor is 34 3/8" from ground........no axle flip with my trailer, as a sub frame would be required and I don't like the looks of a raised trailer....

The 2018 RAM has front and rear coils. Who did you use to make your coil springs?

The Kelderman kit will replace your rear springs, and I read they will get you 2Ē lower.

Anything that drops you 4Ē in the rear will leave you almost no suspension travel, and will probably drop your capacity so low you canít tow the fiver any more. I have the same problem.

As a test, you could always clamp the front coils together to get what you think will work, then test drive.........I have a friend that works for a spring co in Portland..For the rears, I had to add more threads on the U bolts, so no cost there...the rear anti loc brake arm just moves upward a small amount and that just adds a very small amount of fluid to rear brakes....

Raise the RV, do not lower the truck.

Itís Maximum Steel Metallic. I call it dark blue. Most people think itís black until they get close, and when itís dusty people think dark gray.

What they do when lowering a truck is make shorter coils, and to keep the cargo carrying the same, they use heavier gauge wire......

May I ask why you think your truck is too high?

Because I have to have a step ladder to get anything in or out of the bed. I'm too old to be climbing on a step ladder. There is no reason the tail gate be more than 36" off the ground, My RAM is 42"!!

So this isn't about the 5er sitting too low for the truck this is about you not being able to get things out of the bed, your original post didn't really make that clear. Put a bumper step on the RAM or trade it in for a new GMC with that goofy tailgate or the Ford with the ladder built into the tailgate or remove the tailgate altogether. Lots of ways to skin that cat without compromising the suspension on the truck.
