From highway driving, to heavy load applications, the Timbren TORTUN4 will protect your Toyota Tundra suspension, and will improve the performance of your vehicle whether you are hauling hay, performing commercial jobs, or just doing some weekend boating.

The Timbren Suspension Load Booster is designed to provide stability, reduce swag, eliminate sway, and level the vehicle for an overall improved, "rubber cushion" ride - on or off the road. All while maintaining the current ride height.

If your Toyota Tundra leans on turns and curves, drifts on the highway, bottoms out, or provides a general bumpy ride when loaded, a Timbren Suspension Kit is the solution for your suspension problem.

The Timbren Kits we offer are extremely simple to install, require no maintenance, and come with a lifetime of use backed by warranty. The award winning "over load" systems are made of Rubber Aeon Springs and designed to provide maximum performance for stock suspensions. Our Tundra owners love the upgrade it gives to their current supsension. The TORTUN4 is one of the best suspension upgrades you can make for under $200.

  • 6,000 lbs. Level Load Capacity
  • Reduces sag and sway
  • Eliminate vehicle from bottoming out
  • Perfect for handling heavy cargo loads
  • Ride quality unaffected when not loaded

Put these on a 2015 Tudra. No sway or squat when towing a 3 horse gooseneck or when pulling 6 tons of rock. Very easy to install. It takes longer to get your tools out than it does to put them on. They work exactly as advertised.

Easy installation. Need air wrench tho. Towed for first time today and noticed big improvement in ride and handling. It is as good as advertised. Buy the kit. You won't regret it and it's 1/3 the price of airbags without the need for maintenance.

Kit was easy to install and works perfectly... no load ride is unchanged from factory ride (2007 4x4 Tundra LTD with a 2.5" level kit and towing a 7000lb trailer). When fully loaded, the truck/trailer rides a bit stiffer but remains level by preventing full compression of the leaf springs. Sway is significantly reduced as well. I would highly recommend this product to anyone.

Worked as advertised. Would install again on a new truck. The only issue I have is if you have a older truck the bolt you have to remove will be corroded, rusted and down right nasty to remove. I broke one and could not even get a socket on the other. Took it to the local shop and they charged me a hour labour for the install. I can now haul a huge load of wood with out issues.

Easy installation. The Timbren Blocks work perfect. I am now able to tow a larger trailer with more hitch weight. This is what I wanted with no air bags to maintain.
