The Timbren TORTUN4 Suspension Enhancement System is built to improve rear suspension performance for trucks like the Nissan Titan, Toyota Tacoma, Toyota Tundra, and Isuzu D-MAX. Featuring Timbren’s patented progressive Aeon® rubber springs, this system automatically engages when carrying heavy loads to eliminate rear-end sag, reduce sway, and improve stability while towing or hauling. It also helps reduce bottom-outs when driving on rough trails or uneven terrain. The bolt-on kit includes durable steel mounting brackets and all required hardware for a simple DIY installation. Once installed, the system requires zero maintenance and is backed by Timbren’s lifetime warranty.
