DR. NANO Heavy-duty 4WD Torsion Bars offer a spring rate that is approximately 30% higher than OEM bars.
This dynamic increase in spring rate eliminates hard bottoming out when travelling off road and gives better handling in street applications.
They can be installed with a moderate pre-load to raise the vehicle for better clearance off road, or to revitalise the handling characteristics at the standard height.
These performance-proven, easy-to-install bars are especially beneficial when oversize tyres or frontal accessories are installed and are backed with 2 years warranty.
The OEM torsion bars fitted to the vehicle will not withstand the additional weight placed on the vehicle and will be prone to sag and will offer poor handling and offroad performance. DR. NANO heavy-duty 4wd torsion bars feature increased spring rate (thicker bar diameter) to better handle the additional weight and provide far improved handling, ride height and offroad performance.
DR. NANO heavy-duty 4WD torsion bars feature cold rolled splines to increase strength, reliability and ensure a perfect fit.
As torsion bars have load applied in a particular direction during compression travel, we have our torsion bars directionally preset and scragged to prevent sagging and breakage.
DR. NANO heavy-duty 4WD torsion bars feature an increased bar diameter, thicker than the original vehicle torsion bars. DR. NANO uprated torsion bars provide a far superior ride that will greatly reduce bottoming of the suspension and will improve the vehicles handling whilst also offering far greater reliability at increased ride heights.
A thick durable powdercoat is applied to provide protection against corrosion.
DR. NANO heavy-duty 4WD torsion bars have precision end fitment and are marked both left and right hand side, and also importantly front and rear to ensure correct simple fitment the first time. Fitting torsion bars on the incorrect side or back to front will damage the torsion bars as they are preset and scragged in the required direction.
