Sumo Springs or Timbren

Im getting a new lake boat that is about 4k and sag drives me crazy.
Not sure how much there will be till I get it.
Just found out about these products.
Do they mess up offroad performance?
Does upward travel change when unloaded?
Can anyone enlighten me about these product
Thanks in advance

 

I have the black Sumos and I really like them. My boat is about 4500lbs and with it and the box and back seat area full of vacation stuff have less than 1.5" squat. I really can't answer your other questions, although I fail to see how they could mess up off road performance, unless having less compression is a problem.

I can't compare the Sumo with Timbren as I've no experience with Timbren. I'm very happy with the Sumos and there also 15% off this month when bought thru SuperSprings International.

 

I was considering them and asked a similar question earlier this year and my take is that the way to prevent disproportionate rear end sag and still utilize the full mechanical design of the suspension is to use airbags. Sure others will say otherwise YMMVJMHO

 

I will agree that air bags offer the ability to tailor the amount of resistance to suspension, but I wanted something simple and reliable, without compressors, lines and multiple ways for failure. SumoSprings offer that, cheaper to purchase and easier to install, should last as long as the truck with no moving parts or failures to be concerned about.

But I agree YMMV, good luck!

 

I run Timbrens and pull a 6000lb travel trailer and they’re awesome. When not towing you will feel them going over speed bumps

 

I have the blue SumoSprings and tow a 5k boat. No more sag. The ride is a little more harsh in the rear while towing but definitely feels more controlled. There is no noticeable difference well not loaded. If I do any kind of major off-roading I remove them. About 10 minutes each side. Other than that I leave them on. Hope this helps!!!

 

Just thoughts, I've had the air bags on heavy trucks pulling 5th trailers that work well but when MTY you gotta drop air pressure and not allow air bad to have a vacuum. So to think of off roading could be a problem adjusting and a pain to get them right. The Sumo's or good for heavy loads and have them on motorhome but not good when light loaded. I have had travel trailers with equalizer hitches on them that levels out the load and keeps truck level. When done towing you take all off and you're back to normal on your truck. I've never done this on a boat but seems it would work, just thinking. Maybe you know someone who has this setup that you can borrow to test determining if this is an option.

 

Looks like you’re leveled too?

 

Equalizer hitches won't work for a boat. Especially going down a ramp in reverse

 

Im have. 3/1.5 lift. SumoSprings were able to make me a custom set to accommodate the lift. When towing I am just about level.
