How do You Raise The Suspension on a Camper Trailer?


There are different methods to do this project. the first one, which many RVers use is flipping the axle. This will provide you with that couple of extra inches you may need without buying expensive parts.

The drawback to this option is that you can do it wrong and cause damage to your tires and decrease your handling ability. The next method will be to use new suspension spring hangers. Get them in a longer size to get the clearance you want.

However, it is possible that by using this method you will add more stress to the frame if you do not include some extra support. Then you can go to lift blocks or lift kits. One owner had the dealer install them, then weld them to the gusset for that additional support that is needed

So far, according to that owner, there has been no problem despite what others say. The drawback to using lift blocks is that the trailer may become more bouncy and ride rougher. This will put more stress on your suspension and wear out the trailer faster.

If you already own a Winnebago, some of their models already have an adjustable lift system installed. The company put about 3 to 4 vertical bolt holes that allow you to make adjustments without having to go to blocks or use lift kits.

Travel Trailer Lift Blocks


There is a wide array of retailers who will sell you a lift kit. That is the name you should use when making your own search for this product. If you say lift blocks, you will get the standard blocks that your RV or trailer drives over to get off the ground and secure the wheel in place.

The kits come with the U-bolts and hardware you need for installation. They are also priced between $50 and $100 on Amazon. There are other retailers that are more expensive and their blocks do not come with the U-bolts.

Plus, you should be able to find these kits at different outlets including RV parts and supplies, big box stores and hardware outlets. Their prices will vary depending on if you get the kit or just the blocks.

The blocks are designed to fit into the axle and suspension mechanism and lock into place so you do not have to worry about movement or losing one. It would be best to get the kits as they will have the U-bolts you need to compensate for the additional height.

Your old U-Bolts may not have the length to handle that addition. That would mean that you would have to run back to the store to buy new and longer U-bolts if you did not buy the kit.

5th Wheel Trailer Lift Blocks


You can get these blocks but one of the first things you need to check before you buy is the axle rating. The weight rating will determine which lift block option you should buy. There are companies out there that sell lift blocks that are designed to work with axles with a 1000 to 7000-pound weight rating.

The other thing you should be cautious about is your warranty. Some RV brands may state that they will void the warranty if you install lift blocks. On older trailers, this may not be an issue but on newer ones, it can be.

RV makers are good at pointing to any modification you make to your trailer and claiming it was responsible for the accident or other issues that arise over your use of the trailer.

Check your warranty first or call your dealer to see if that will be a problem for you. If it is, you may have to plan on staying at those campgrounds that have ideal access roads.
