Our SDHQ Motorsports traction bars are adjusted and ready to go!
We tested the SDHQ Motorsports traction bars doing burnouts and drag starts, in cornering, hard braking, towing and off road as well as daily driving on all sorts of road surfaces. We found that the traction bars help traction in a drag start quite a bit by totally eliminating wheel hop. Even when doing a burnout, the wheelspin is totally smooth with no added stress to the drivetrain. Wheel hop we experienced when spinning the tires off road is completely gone as well. Perhaps the biggest positive difference is on the street when accelerating away from a street corner. The huge wheel hop we used to experience that would set off the traction control is eliminated. This greatly reduces the auto bog where the truck would lurch out into traffic only to have the traction control cut power right when you needed it the most.
In high speed cornering, with the swing links articulating eliminating bind, there is no effect on roll stiffness and the trucks cornering understeer/ oversteer balance remains the same. Also when transversing ruts and uneven dirt off road, the rear axle can still freely articulate so traction is not affected in this way. The traction bars also help with braking, the rear wheels have better traction and ABS activation seems to come later. Despite all the solid delrin bushings and heim joints, the traction bars add no detectable noise, vibration or harshness. By stopping axle wind-up and severe pinion angles, the traction bars will also reduce wear on the driveshaft and the differential.
The SDHQ traction bars are pretty amazing, they help in many ways and have absolutely no negative issues that we could find, there is usually some sort of trade off with any higher performance product but not these. We recommend these in everything from a stock to a highly modified Tundra, they are a great asset if you drive hard!
