This kit is a Discovery 1 Rear Doughtnut Removal Kit. These rubber couplings are very prone to failing - especially on vehicles used off-road or on vehicles with lifted suspensions.
Remove the old propshaft on your vehicle along with the 3 bolt style diff flange and replace with this kit for an instant upgrade that will give you piece of mind in the knowledge that you won't need to replace TVF100000 every 2-3 months.
