• Air Ride Suspension System for 2011 Toyota Tundra with a 6 inch Lift
  As long as you don't have a 5th wheel or gooseneck hitch installed, then we have a Firestone Ride-Rite kit that will work for you. I recommend installing the Ride-Rite Kit, # F2445, because you can use the Ride-Rite Lift Spacers for a 6 inch Lift, # F2375. These two parts will accommodate the 6 inch lift on your truck. The Ride-Ride kit will not fit if you have a 5th wheel hitch or gooseneck hitch installed in the bed. I'm not sure what type of lift you have, but if your truck is still...

• Best Way to Control Sway for 2010 Toyota Tundra That Has Anti-Sway Hitch
  Ok, so there's a couple of things you'll want to do first, and that's just make sure you check your tongue weight. You'll want to be somewhere between 10% and 15% to ensure your trailer is loaded properly and the weight is distributed evenly. Additionally, a trailer that is 10,000 lbs is very close to the upper capacity of your 2010 Toyota Tundra 4WD, and that truck towing a long 34 foot trailer with that much weight is going to cause some sway, even with a weight distribution system. While...

• Best Suspension Enhancement for 2021 Toyota Tundra
