Roadsafe 4wd Diff Drop Kit for Toyota Landcruiser 300 Series - DDLC300!!! FREE POSTAGE !!! When lifting a Toyota Landcruiser 300 Series, the Constant Velocity (CV) joints are put on an increased angle. This increased angle of the CV joint during operation can accelerate the wear on the joint, as well as putting additional stress on the CV boots leading to splitting and eventually premature failure of the CV. The Roadsafe IFS Diff Drop Kit is supplied complete with all the necessary replacement diff arms and fitting kit.
