Is a Lift Kit Available for Rockwood Fifth Wheel Trailer?

Question:

Torsion Axle Lift Kit - Rockwood 2895WS 2014 Fifth Wheel. I own the fifth wheel above and find there is only about 1inch clearance between the top of the tire and the undercarriage and this seems too small. Also the RV now scrapes as we pull it out of its park when we pull it up the drive and return it. It scares my wife that we have so little clearance. We had a blow out last March 2017 with no damage but on our haul down to Sonora MX from BC Canada we blew another tire right rear and this thing took out all the electric cabling and propane connection. US$3,000 later - Insured thankfully. The dry weight on our rig is around 8,000 lbs and its a signature ultra Lite. Cheers

Your wife is not wrong because an inch of clearance is not going to be enough; there needs to be roughly 4 inches for the suspension to have enough room to travel. If your tires are rubbing when you drive this will be the reason for your blowouts.

The torsion axle lift kits you were asking about will provide you with a decent amount of lift but you'll need to make sure they fit your specific axle. The # K71-724-02 will provide 2-7/8" of lift and works with # 11 Torflex axles that have a weight capacity between 4,100 lbs and 6,000 lbs. The # K71-725-02 provides 3-1/8" of lift and will work with # 12 Torflex axles that have a weight capacity between 5,500 lbs and 7,000 lbs.

If you have a round axle and double-eye springs you can use an over-under conversion kit to "flip" the axle and gain the amount of lift that your axle is as well as the width of the leaf spring stack. The Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 is for a round 2-3/8" axle while # K71-385-00 is for a round 3" axle. I've added links to video reviews of these parts for you to take a look at.

Aside from those products you are also going to want to make sure you have the correct tire size that is recommended by the manufacturer and that you are not overloading it. I also recommend taking a look at the suspension components to see if there is a worn-out or otherwise damaged part that needs to be replaced; if you are not experienced looking over these parts I recommend taking your rig to qualified shop that has experience with RV suspension and they will be able to tell you if there are any parts that are damaged or worn.
