Question:

Hi, I have a 2016 Outdoors RV Timber ridge model 26RLS. The max. loaded weight for this trailer is 9200 pounds. It is 32foot long with hitch. I had a previous half ton truck that handled it well and just upgraded to a new 2020 GMC 1500 Denali crew cab short bed same configuration as my previous Chevrolet. Now my 2020 GMC has a sag of appx. 4inch when the trailer is connected. I do not want to void the warranty of the new truck but I do want to get rid of the sag. I already use a weight distribution hitch, I believe it is a E2 weight distribution hitch E2 Trunnion Hitch 1000 lb max tongue 10,000 max trailer. Can you recommend something to help me with the sag that will not void my new truck warranty and wont affect my ride quality when not pulling a trailer? Is that possible?

THe RoadActive Suspension Custom Leaf Spring Enhancement Kit part # RAS4611 that you looked at is a good option. It will not completely remove the sag but it does help. It also makes an improvement to the unloaded ride quality. Less body roll and and more responsive steering are great side benefits of them.

Another option is the Firestone Ride-Rite Air Helper Springs part # F2609 these will allow you direct control for 100 percent level ride.

Of the two I recommend the Airbags. In your situation you will be able to add or remove air to get the perfect ride height.

I would also readjust your weight distribution system. With the weight of the system and camper you should be able to get the camper back to close to level. You will need to adjust the arms of the system so they are lower on your Fastway e2 Weight Distribution w/ 2-Point Sway Control part # FA92-00-1000. I have included the instructions for this.

With any of these you choose you will not have any issues with a void being put in your warranty.
