Overview

The Dobinsons TB43-300 is a pair of heavy-duty torsion bars designed to improve front-end suspension performance and ride height. These torsion bars feature an increased spring rate to better handle additional weight, providing improved handling, ride height, and off-road performance.

Constructed with cold-rolled splines for increased strength and a precise fit, the torsion bars are finished with a durable black powdercoat for corrosion protection. They are directionally preset and scragged to prevent sagging and breakage, with clearly marked left/right and front/rear sides for simple installation without modification.
Show original supplier description
The Dobinsons Heavy-Duty Torsion Bars (TB43-300) are engineered to significantly enhance the front-end suspension performance and lift of your vehicle, particularly when carrying extra weight from accessories such as bullbars, winches, or dual battery systems. This design effectively combats sag and improves handling, ride height, and off-road capability, reducing suspension bottoming and enhancing overall vehicle stability. The bars are precision-fitted with cold-rolled splines for superior strength and reliability. For durability and longevity, the Dobinsons torsion bars are finished with a thick, protective black powdercoat to resist corrosion. They are directionally preset and scragged during manufacturing to ensure they maintain their integrity and prevent sagging or breakage under load. The ends are clearly marked for left/right and front/rear fitment, simplifying installation and ensuring correct placement without the need for vehicle modifications.
