Use something like an oil filter band clamp wrench if needed.

 

Hadn't thought of that, thanks for that idea.

 

I’m confused. On my ‘05, I just loosened the leaf suspension U-bolts, pulled out the stock ones and inserted the Sumo Springs. Done.

 

Sumo springs are just long, rubber bump stops. Easy install.

I'm not changing their actual springs, but the bumpers. Looks fairly easy. I also have a pair of filter plyers that I can use.

FYI, the factory bumpers pull right off without having to jack the vehicle up. I reached over the tire and pulled and they both came right off. Now to get the bolt out.

 

It sound like your setup is a little different than my 1st gen Titan. I had to jack the truck and loosen the u-bolts for the “cups” to clear for removal.
Now I can load a pallet of wood pellets (1ton) and the truck sits level. I bought the highest rating Sumo Springs. I think 1500 lbs.

Took about 30 minutes to change them out. Never had to put the tires in the air. Maybe 1/2" clearance which is much less than the stock. SS recommended I use the 1000# springs since I don't haul fulltime. Should take out the occasional bounce when hauling my 26' travel trailer once a month.

Edit: Yes, mine mounts above the leaf springs.

 

This is what it looks like.

 

The 2018 TITAN mounts the unit on the frame, not the axle. Sumo provides the base, hardware and loctite to complete. Did the install in the garage in 45 minutes with floor jack/stand. The factory bottom stops were easy to twist out. The bolts in the plates to secure to the frame were the pain. Installed the Sumo plate with the blue loctite, then screw the Sumos to the plate. Let mine sit 36 hours and instant success. I have to travel on dirt/gravel but after 8k miles not a problem. Guys at Discount Tire were impressed by my 'heavy duty' bottom stops when I put the Firestone load range E rated tires on.

 

Good to know when I decide to upgrade to a 2nd Gen. Thanks!

 

Pulling the travel trailer 4 1/2 hrs tomorrow. Looking forward to testing the performance.

 

You are using a WDH, right?

 

Yes, I am.

 

Looks like if you adjust the stinger down some more and get the spring bars more level with the tongue you will get a little better weight transfer.

 

Agreed. Just got back with it and noticed I likely should add a link.

 

If you tilt the top of the hitch away from the truck a bit more, and stick with 3 links dangling, and the bars are parallel to the trailer, you should have it set.

 

The Transcend campers are very nice. Look very well built.

 

I did a lot of research before deciding on the Grand Design brand and we are very pleased with the rig. Wish I had gone with a different WDH system but for now, this one will have to do since it is fairly new. A learning thing.

 

I set mine up the easy way. I let the guys at the camper yard set mine up when we picked the camper up. They had it done in no time. My setup was free with the camper purchase. I would have bought a trunnion bar setup if I had to do it again.

 

The RV dealer set mine up also. Problem was, I had bought one through Amazon that looked like it had been drug behind the UPS truck when it got here. No chains on that one but it went back and I had no choice other than taking the one the dealer had at the time since I was taking delivery the next day. I would have preferred a Husky Centerline. It pulls fine with this one so it's hard to want to change at this point.

 

Good info - based on this and other research I've ordered the Blue (1,000lb) SumoSprings for my 2018 Pro4x as well. Same as BillM I also removed the Pro4X decals from the sideboards - I think it's a cleaner look. I'm pulling a 2016 Outdoors Recreation Vehicles 23BHS - it a 27.5' trailer that weighs in about the same as your GD so am glad to hear you seem to be able to tow it well. I'm a little concerned with my payload (or lack thereof) so know I will have to pack carefully and selectively. Thanks for the good info.

 

I've made several trips with my Sumos. My trailer is a 2018 Jay Feather 23RL with one slide, weighs in at 5,500 loaded. I switched to Andersen weight distributing with sway control after using an Ultrafab spring bar for eight years. I put Sumos on my 2015 F-150, Timbrens on the 2019 RAM, when FCA Lemon Lawed it, replaced with the Titan...and Sumos. (Don't think Timbrens makes anything rated less than 6,000 lbs) I had to pull another trailer I own last week (25 mile round trip) and did so without weight distribution or sway control. Sumos kept the ride height within a couple of inches of unloaded height dragging a 7,000 lb 30 ft rig. Would not try this again without the full compliment, nor try any long distance run.
