These fit Toyota 2ZZ powered Lotus models w C6X transmissions. They are an improved versions of the OE part.
Each pair comes with replacement inner and outer boot, moly grease, and clamps, sufficient to reboot 1 axle. The boots are the same for the left and right axle.
The outer joints are knock-offs and the inners are retained with a clip. No special tools are required for axle disassembly. You will need crimping pliers for standard Oetiker style clamps.
If you are going to the trouble of rebuilding these joints, you might consider using REDLINE CV-2 grease, available here, rather than standard CV greases.
