following up on my question yesterday.. What is the difference in performance / ease of installation between this and the 1139-143? ( JOHN TAYLOR, 02/08/2019 )
This sway bar is much easier to install as it bolts to the lower shock bracket instead of having to take the u-bolts loose and adding big mounting plates. Better performance with the 1139-145 as well because the attachment points give it more tension on the suspension to provide the best sway control possible. ( Support )
can I install this with the trac bar (UTF53V10R) ir will they interfere with each other? ( John Taylor, 02/07/2019 )
You can install them together, they do not interfere with each other. ( Support )
