Coming from ST Racing Concepts are three new option parts for the HPI Venture FJ trail truck. First up is a CNC-machined brass front or rear diff cover that adds precision to the axle and the differential gear mesh while adding more weight – 23g a piece – to the axle. Also new are brass rear lock-outs that add more weight to lower parts of the rear axle – almost 50g – and improve the alignment of the rear driveshaft over the stock plastic lock-outs. Last but not least comes a CNC-machined centre transmission case which offers better transmission components alignment and add another 36 gram to the lower centre portion of the Venture FJ. The centre transmission case is available in silver anodising.
