Heavy duty drive flanges for Toyota solid front axles. These flanges are much stronger then factory drive flanges or lock out hubs. Flanges feature a larger center section with more support for the splines. Made from hardened tool steel (4340 Chromoly), these hold up much better to the kinds of toque possible with today's heavy duty aftermarket axles. Kit includes 2 flanges, 2 dust covers, 2 cover seals, drill bit and 12 heavy duty studs. Additional studs share the load, preventing hub stud and bolt failures common to stock drive flanges and hubs. Flange covers feature a Trail-Gear exclusive O-ring for a water proof seal. If your running stock hubs on your truck, drive flanges make a great trail spare for your tool box. If your stock hub gears fail on the trail, drive flanges can be quickly installed to restore 4wd. Fits 1979-1985 Toyota Pickup/4Runner solid front axles. Recommended for off-road use only, not recommended for use on the street. We recommend that flanges be painted before installation.
