5th wheel lift

My 08 cruiser fifth wheel is short in height for my truck. I wondering if anyone has put a lift block kit on their 5th wheel to gain some height so it runs level with truck.. any info would be appreciated!

Last year I replaced my 15" ST tires and wheels with 16" LT tires and wheels. This raised the trailer just under an inch. Last week I put a wet bolt kit on the suspension. The springs were originally in the upper holes in the hangers, but when I reassembled the suspension with the wet bolts, I used the lower holes. This added another 1 5/8" to the height. Combined, my trailer is about 2 1/2" higher than before. When I head out on my next trip in a week I'll know how level it now tows.

Let me know how it turns out! I just bought brand new 15”tires so that’s not an option for me at the moment.

Check out the "Correct Track System" it will raise the camper 2" and also allow you to align your axles. Some campers come with it from the factory.

Where do you find 16" rims to fit the 15" rim bolt pattern?

I got them at http://www.tirerack.com. I got the tires there too. They came mounted and balanced and inflated to 80 psi.

You should be able to lower the pin box on the RV.

Some times you run into trouble doing that. Like on mine, if I go any lower I run the risk of the pin box hitting the box rail of the pickup.


The truck makers didn't do us guys with the older 5th wheels any favors when they built the new trucks.

Lloyd, let's think this out. Lowering the pin box will raise the 5th wheel. Since the hitch is at the same height, the bottom of the pin box cannot go any lower than it was when the pin box was higher.



So, in reality, you are not lowering the pin box, you are raising the 5th wheel.


Correct??

You are correct Mark. I had the hitch in my mind. Must be a Sat. brain fart. Sorry.

Lowering the pin box will raise the front of the trailer causing it to tow nose high and putting more weight on the trailer's rear axle, especially with the taller trucks.

I had/have the same problem. From my calculations the trailer was about 4" nose up. I looked into a spring-over-axle but that was already done, adding blocks to the trailer springs but there was already more space there than I wanted, lowering the truck, changing the settings on the kingpin box and/or hitch but if I did that the kingpin box would hit the side/tailgate. So I finally went with a tire upgrade from 15" to 16" (Goodyear Endurance). I bought the tires and wheels from Discount tire. It raised the whole rig about an inch.

I can't say nice enough things about the guys from Discount Tire. They helped us figure out which tires and wheels would fit. We also decided that we wanted TPMS on the trailer. They didn't have one that would work on the trailer but my wife found one on line, ordered it, and they installed it for free.

I just got back from a two week vacation from OKC to the Denver area. The truck and trailer ran just fine. ...except for needing new tires on the truck. ...the upgrades and repairs never end.
