Description:

Comfort Ride Slipper Springs

Have you ever opened the door to your trailer after a road trip and looked into your own personal earthquake zone? Cabinet drawers wide open with their contents strewn over the floor? Pictures off the wall? Furniture that's 'walked'? If buying 50 bungee cords doesn't seem like much of a solution, then let Comfort Ride Slipper Springs solve what's actually causing the problem — outmoded components which transfer energy, rather than absorb it.

How are slipper springs different than my trailer's leaf springs? Travel trailers and fifth wheels use traditional 'eye to eye' leaf springs which haven't changed much for 100 years. If you look at a horse buggy from the late 1800's, it has leaf springs very much like your trailer. This is why your trailer is constantly bouncing and swaying. When your front tire hits a pot hole, the front leaf spring reacts to it and telegraphs that energy through the equalizer to the back leaf spring. Then, when the back tire hits the same pothole, it happens all over again in reverse. You basically get twice the bounce with every bump. Comfort Ride uses Slipper Springs to break the connection between the front and rear axle. Both the front and rear springs will slide forward and backward in response to road conditions WITHOUT transferring energy to the trailer. This movement absorbs and dissipates a significant amount of energy that would otherwise make your trailer ride rough, sway and tow poorly.  

Did you know that on a typical highway, your trailer experiences the equivalent of a 3.2 magnitude earthquake?  It is shocking how much force is relayed from the road to the trailer. Forces that twist and flex the frame causing brittle roof seams to crack and leak water. Forces that cause sofas and stoves to vibrate out into the aisle. Forces that require you to remove loose belongings from shelving and walls each time before you tow. Comfort Ride ends this pre-towing ritual by absorbing the forces rather than transmitting them throughout the trailer or fifth wheel.

Stop the white-knuckling! Many trailers and fifth wheels can be a handful to tow. On poor roads, they can be downright scary. A major reason for this is the driver must constantly react to the forces the trailer is applying to the truck. Comfort Ride calms the energy from your trailer, resulting in a better ride and more control.

Improves your trailer life — Comfort Ride can absorb 80 percent of the forces that may create water leaks and damage your trailer over time. If you stop the twisting and flexing, you stop the cracking and breaking of room seams and sealants.

Reduces trailer maintenance — Comfort Ride Slipper Springs eliminate 10 of the 14 wear parts from a conventional trailer suspension. The remaining four parts are replaced with self lubricating bushings. This means less wear and tear, less maintenance and fewer repair bills. 

IMPORTANT! Select the right springs to match the true load of your vehicle!

Choosing the correct spring rating is critical. Either too light, or too heavy of springs, will negate the benefits of the Comfort Ride system. Ideally, choose a spring rating that just exceeds the actual weight on the axles. Don't jump to a heavier spring, if it isn't necessary. Doing so will create a harsh, uncomfortable ride like that of an unloaded one-ton truck. Conversely, springs rated too low for your loaded weight can fail causing non-warranty damage.

To determine the proper rating, visit a truck scale with your trailer fully loaded to verify how much weight is actually on the axles. Use springs rated just above your real-world axle loads. For example, if your trailer has two 8K axles (16k total) but the load on the axles is only 13,600 lbs, then use our 7k spring kit (designed to carry up to 14k total).

For more information about which capacity springs are appropriate for your trailer, see frequently asked questions below.

IMPORTANT!
Trailers with under-slung springs must have the springs relocated to the top of the axle during installation: this raises the trailer and provides the necessary ground clearance for the shocks. Failure to do so may cause the shock to drag on road hazards (pothole, speed bump, etc.) or even during a flat tire. This will result in shock failure and non-warranty damage. Before completing installation, verify that the shock absorber mounting bracket does NOT extend below the wheel rim.

Comfort Ride will significantly reduce the cause of these common symptoms:

Chucking — the truck is rocked forward and aft when the trailer goes over uneven pavement (dips, frost heaves and the infamous bridge expansion joints)

Axle roll-up — during braking, the trailer's rear tires are lifted enough to cause a loss in traction (and a rise in the driver's blood pressure). Axle roll-up is why your back axle tires occasionally lock up momentarily when stopping. The harder the stop, the more prevalent it becomes.

Suspension rebound — when one tire goes over an obstacle, the trailer tips sideways. After the tire clears the obstacle, the leaf springs (and the trailer with them) rebound like a pogo stick.

Although Comfort Ride Slipper Springs can be installed separately, they work best when combined with the Comfort Ride Shock System. When used together, on smooth roads you can expect up to a 50 percent reduction in induced road energy transmission into your RV, over cobblestones a 76 percent reduction, and over gravel roads a 94 percent reduction.

Kits include four slipper springs, patented slipper box, hardware, and detailed instructions. Each kit contains the components for a tandem axle trailer. To get the correct leaf spring capacity, you will need to know your trailer's axle weight rating.
