Sumo springs

Just installed 1500lb sumo springs, I'll be towing a tt about 2000m here in a month or so. I have a topper and bed slide and keep a bag of assorted stuff in back of truck. Put new ubolts on it as well. I was amazed, my pro usually has a 1" or so of squat, it now has a 1" of rake, with my wdh I expect to be really level towing now.

 

Yes, Sumo springs are good for carrying a load, but they limit axle articulation with stock leaf packs. Check out Roadmaster Active Suspension. I have both plus HD leaf packs. Good luck!

 

I'm not sure I'll run them long term, but I definately need them for this trip, won't be doing any off roading where I'm worried about full articulation, but has to be better on those leaf springs to not have that constant load, expected to get back to level, didn't expect to see rake, felt fine in the short amount of road time so far. I may cut them down after the move as an oversized bump stop or may leave them on since the springs can't support the topper and load in back of truck.

 

Trust me, I've been there! Stock leaf springs have one purpose, connect the axle to the frame during initial sale of the truck. Great for Toyota shareholders, as for the guy who loads his truck....he's SOL. Cost me about 3k to get a decent load carrying/towing suspension in place just for the rear. Another few grand up front, plus some decent E Rated tires. I also chose to put in the tranny cooler that cheap ass Toyota removed from the design. Still wanting to do a high performance valve body and extra deep pan. Did you add a tranny cooler?
