Frequently Asked Questions

Do I need to replace both shafts at the same time?: Not required, but recommended if one shaft shows wear — both shafts experience the same stress cycles and often wear at a similar rate.
What's the difference between 1951 and 1951R?: 1951 uses plastic half shaft bodies with metal U-joint crosses. 1951R is an upgraded set using steel-spline constant velocity (CV) half shafts throughout — a heavier-duty option for higher-power builds. Verify which version your vehicle uses before ordering.
Can I pick these up at your Greeley store?: Yes — JackWagon R/C & Hobbies is located in Greeley, CO and stocks Traxxas parts.
