ST Racing Concepts Aluminum Rear Pivot Block Set (RF/RR) (Blue)
Very good upgrade and well worth the cost. Stock ones broke every 2 weeks, these have lasted for months now. Be sure not to use the steel bushings on the hinge pins with this block set as it will wear it out... you have to use the white plastic ones from Kyosho or just the stock black ones.
