The TR10013 TRX-4 rear door mount Type1 was created to replace the heavy rear spare tire and mount on the stock Traxxas TRX4 Defender body. This design allows you to reconfiture the stock gas tanks whilst still keepin the highlift jack in the stock position (those come included with the Stock TRX4 Defender)
We recommend this version if you want to fit the optional Knight Customs TR10015 TRX-4 rear ladder (sold seperately).
PLEASE NOTE: You can also repalce the stock gas tanks with our officially lincensed RotopaX fuel packs (sold seperately).
