## Questions & Answers

**Q: Does this come with 2" or 1.75" leaf springs?**
A: 1.75”, springs are 3/8” thick, ride much harder than original Lippert Springs. Less moving parts, but much harsher ride.

**Q: In the description it says that it comes with Nitrogen-charged shock absorbers. I don't see the four shocks or the hardware to mount them?**
A: This sku is for the Slipper Spring System only.  The shocks are sold separately.  Most trailers have a 3" diameter axle.  If that is what you have then you would need the Comfort Ride Shock kit pn 2460.  If you have 3.5" diameter axles, use 2470.  Some smaller trailers might use 2 3/8" axles which are part number 2450.  Ideally the shocks and slipper springs work together for the best ride, but if I was only going to put one thing on the trailer it would be the shocks.  That said, much of the labor to install these kits is the same regardless of which kit you install.  Accordingly, you can save quite a bit of labor by doing them both at the same time.

## Customer Reviews

### ⭐⭐⭐⭐⭐ If you’ve got a 5th wheel, you need this.
*by D***. on October 30, 2024*

About as close to an independent suspension as you can get without spending thousands. Slipper spring and shocks together make you forget you’re towing anything. Everything in the RV is less rattled and shaken. If you’re going to use your trailer on long trips or often, this will save you money in the end. My 5th wheel isn’t getting beaten up by bad roads anymore.

### ⭐⭐⭐ They changed the spring size from 2 inch to 1 3/4 inch
*by C***. on November 1, 2020*

I installed this on my 5t wheel toy hauler. I ordered this because it came with 2 inch springs. Roadmaster has changed the spring size to 1 3/4 inch springs which is the size of most springs are on 5th wheel trailers. I had purchased special U-hangers to accommodate the 2 inch springs. I talked to the designer of the Comfort Ride kit who sold it to Roadmaster. He deliberately went with 2 inch springs because it is a better spring. I called Roadmaster and they still had some 2 inch springs and they sent them to me free of charge. If you are ok with 1 3/4 inch spring the go with these. If not you can get the the original system from Twisty.com with the 2 inch springs. The only other problem was drilling the holes. It will take you some time. I suggest you use a tap on the hole also. I sheared the last one of the self tapping screws off when installing. It took forever to drill out the self tapping screw. I went with the slipper spring system because my Equaflex equalizer shackles broke. I did not want to happen again. To use this system you need to have a level trailer. If not you will be putting more weight on the rear axle. According to the designer it is a hundred pounds for every inch difference. The trailer rides much better now.

### ⭐⭐⭐⭐⭐ missing screws
*by D***M on July 16, 2020*

2 screws were missing from box. Called Road Master and they suggested we look for replacement at a hardware store. We have looked and searched online to no avail. We ordered on Amazon. The irritation is getting this repaired on our RV, we are only here for a few more weeks.
