Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers - Tandem 7K Trailer Axles
Very good quality and quick delivery
Install wasn’t bad. Grand design welds a V bracket inside the spring hangers for more strength so that was my only challenge on install. This caused a problem on the center hanger as the spacer wouldn’t fit. Had to grind about a quarter inch off the spacer so it would fit as I could only bend the bottom of the hangers so much. Will be towing about 100 miles this weekend so it will be nice to hopefully not have broken drawers in the back of the trailer as well as shelves in the fridge door dislodged. I also did the X factor cross braces on the front and rear hangers for more strength. Will post back after we get more miles on it, but given all the other positive reviews I don’t think I’ll be unhappy.

U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles - 7" Long U-Bolts
I upgraded my leaf springs to 4000lbs springs and needed longer axle U bolts and Quinn at etrailer was helpful getting the correct bolts headed my way.
These seem to be working ok but do not appear to be designed for use with the HD upgraded Moryde greaseable shackle kit that I purchased with them . You can see in the photos that they rub and bind

Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 3" Round Axles - 7,000 lbs
I used these to replace the leaf springs and equalizers on a 20’ gooseneck cattle trailer that I rebuilt. The ride is great and the usual rattling and clanging of the trailer going down the gravel road is gone. So far I am very happy with the ease of installation and the performance of the suspension. I guess only time will tell about the durability of the rubber components in the long run.
Happy with the online ordering.

Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 3" Round Axles - 14,000 lbs
Been great so far..fabbed removable axle system with the timbrens
Seems like a great product and service was excellent. UPS lost one of the three parts and was a week long in delivering it, and then said that it was because it was packaged poorly from etrailer. I used a 4x6 steel rectangular tube spacer to get my trailer back up to the original height. Seemed pretty straight forward, but it would be nice if the system could be designed so the user doesn't have to cut the mounting brackets off the axle and re-attach the Timbren brackets.

Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 5,200-lb to 7,000-lb Axle
Very good quality and quick delivery
Installed a year ago, I made a drilling template to help locate the frame mounting bracket screw holes. Installed a set on (2) fivers, spent average of 2.5 hours for total installation per fiver. Helped the ride of the trailer. Would certainly recommend the shock kit.

U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles - 7-1/16" Long U-Bolts
Ordered a lot of parts for a dump trailer rebuild in Sept. Didn't install some of the final parts until Christmas break. THEY SENT COARSE THREAD NUTS INSTEAD OF FINE. I ruined 2 u-bolts and need all 16 fine thread nuts. I'm outside 60 days so I was told I'm on my own. I've spent $5k+ on etrailer. I'll find some place else.......
Exact replacement for original parts, easy install

CE Smith U-Bolt Kit for Mounting 5.2K to 7K, Round Trailer Axles - 7" Long U-Bolts - Zinc
The product themselves are quality however, the customer service and shipping is what was dissapointing. I originally ordered 4 items. I was told only one item was on backorder. Not a big deal. I checked a week later on the backorder and was told that they did not know when an item would come from the namufactuere. However, it was a different item from the first. So two items were not available and turned out to not be available. It was a lack of communication and I had to figure this out by calling after waiting a week and several misguided emails. Next was the packaging. It was all broken up and taped when I got it. Whoever packaged these items threw 4 heavy leaf springs and 2 sets of U-bolts into a box without securing them. They arrived but the two U-bolt packedges were previouly opened and sealed with masking tape and i'm missing all the nuts and lock washers from one package. The box could have come open during shipment but they were not secured inside the box at all, which led to the catstrophy inside the box. Due to all this, I will probably not order again from this site.
The bolts worked great but the base plate was not drilled out enough to be able to fit, I had to reuse the old plates which worked fine.

Timbren Silent Ride Suspension for Tandem Axle Trailers - 3" Round Axles - 35" - 14K
I installed this on a 2018 wildcat 383mb 5th wheel which has a GVWR of 14,059# and with a weeks worth of stuff for a family of 3 I have 10,700# on the campers axels per CAT scale so this is a perfect fit for the application. Now the hard part was figuring out what the ride height (bottom of my frame to the center of the axels) would be since Timbren's documents only show the unloaded ride height at 6.125", with the stock leaf springs my ride height was 9.375” so that is a 3.25” difference but that doesn’t account for suspension sag. I called timbren they said the ride height at 14,000# would be 4” so basically the suspension would sag 2.125" so I guessed my ride height at 11,000# would be 5” or 1.125” of sag. Based on those numbers I would need to make up 4.5” of ride height so I put a 4”x4” 0.25”wall square tube between the frame and Timbren suspension. Well the Timbren sagged more then I expected, and my final ride height ended up being 8.25”, a full inch lower than factory. I have a lot of overhang behind the rear axel and would drag on occasion at the stock ride height so this inch lower is going to make it worse. I’m going to make a few trips and see how much more the suspension settles then I might go back and add a 2” spacer to raiser camper. The install took me 2 8hr days with the first day being removing the stock leaf spring setup and prepping the axels/removing the leaf spring pads. The hardest and most time-consuming part was removing the spring hangers off the frame man they did not want those to come off. The instructions don’t tell you where to set the axel camber/arch so it set it to the same angle as the suspension arm when unloaded, 19deg which when loaded and on level ground turned out to be perfect. The instructions also tell you weld the axle to both sides of the axle seat well you can’t get to the inside axle seat since it’s so close the rubber spring. Now as for the ride what a major difference I used to dread hitting bridge expansion joints now it’s no problem, the bucking has been drastically reduced. We would always have open doors and draws when got to a location now they all stay closed. Items in cabinets are still where we left them, cereal boxes are still upright.
This system is a 100 times better then the spring system that was on it new. We put about 5000 miles on our 5th wheel per year. It is a 2015 Columbus and we love it but the suspension was the typical junk under most RV’s. Springs that are as wide as the frame so the perch mounts stick out past the frame. Basically they are like what you would buy at [generic retail]. They sheared off at the frame and the axle cocked. Over a short amount of time the tire blew and wiped out the side of the RV. The suspension I bought from etrailer was great and fixed all the problems the original suspension had. It was a bit of a trick to figure out ride height of the new suspension. You have to add spacers under the original frame to achieve original ride height. Sounds hard but it is pretty easy.
