Boss Dropbox Kits

Toyota Landcruiser Dropboxes – suit 3″ and 4″ lifts

Australian company, Boss 4WD, has designed & engineered a Dropbox system specifically for the Toyota Landcruiser 80 Series, that fits and works perfectly.  These Dropboxes solve the problem of track rod clearances and castor correction issues when fitting 3-4″ to 6″ lift kits.

They are simple to fit, deliver a desirable degree castor angle, and allow further tuning of castor angle using offset bushes to trim the final angles using your original radius arms. The Boss Dropbox design is strong, negates any transverse load issues, and delivers correct angles and clearances at the nominated lift.
