Hi all,

 

I recently bought a used ATC Ocelot and have it on a 2019 Toyota Tundra. I beefed up the rear suspension with Ironman4x4 heavy duty leaf springs and shocks (rated up to 880lbs). I haven't taken it offroad yet but, on pavement (freeway/highway) it has horrible bouncing when going 65mph. 

 

I am wondering what will fix or reduce this bounciness. Should I add air bags or Timbrens? What are your thought? Thanks!

It looks like you have an Access cab with a 6.5' bed. Good! I call those crew cabs with a 5.5' bed "toy truckers" because a serious working truck has at least a 6.5' bed! 

 

 I have a 2013 Access cab Tundra with a Hallmark Milner which is heavier than your rig. I had an extra set of leaf springs installed after I had a leak in my airbag system. When they installed the leaf springs I had them check my airbags and they found a leaky brass elbow and with that fixed, no airbag issues. My rig rides rock solid even at 75mph. No sway either. I adjust the pressure in the airbags depending on the load(how much water, and stuff).

Haha yeah, you can't do much with a 5.5' bed. The new Crew Max Tundras finally have an option for the 6.5' bed but those new trucks cost an arm and a leg, a few souls too. 

 

Thanks for your response. I guess I'll be on getting some airbags with cradles since my rear is lifted.

If your truck rides level with the camper on, the issue is far more likely to be shocks than springs, and adding air bags won't accomplish much if anything (neither will Timbrens). It's the shock absorber that attenuates spring oscillations such as you describe.

I would get some good weights front and rear. Then call a good shop that times the shock to your use.

I used Accutune and am very happy with the way my fox shocks are working.
