This is the CVD Kit for the Center Drives of the TRA T-Maxx Truck Only. This goes between the front or rear gear boxes and the transmission. FEARUTES: Black metal dogbones Black steel wheel shafts Included thread lock and lubricant Contains front and rear CVD Two dogbones Two wheel shafts (axles) Two couplings Two output cups Two 4mm set screws Two cross pins One tube CVD lube and One tube thread lock One MIP decal sheet One instruction sheet Removing original half shafts, then installing CVDs. The CVD takes the place of the original half shafts. This Will Not Work with the E-Maxx because it uses 6mm output shafts and the T-Maxx uses 5mm output shafts. jim 1/03/01 ir/jl &
