The J5D Rear Suspension Holder Set takes our Brass Narrow RF Suspension Holder and our 7075 Narrow RR Suspension holder and pairs them together at a discount for our customers.
About the Brass Narrow RF Suspension Holder:
Our new Brass Narrow RF Suspension Holder features the new narrow pivot geometry that is standard on the 2017 XB2 DE, as well as the 2018 XB2 CE. Weighing in at nearly 21g (20.8g to be exact), the J5D version is just over twice the weight of the optional factory brass RF suspension holder. It utilizes factory hardware, and has a nice relief on the left side to allow fan mounting behind the motor.
Compatibility: XRAY XB2 CE (all), XB2 DE (all), XT2, and J5D XSC2.
About the 7075 Narrow RR Suspension Holder:
The J5D 7075 Narrow RR Suspension Holder was designed for the J5D XSC2 to utilize the new XRAY narrow pivot geometry for better traction and driving feel, while also allowing the use of the rear bumper on the XSC2.
As shown in the pictures below, the new narrow suspension holder can also be used on 2017 XB2 and 2017/2018 XT2 models, and when paired with the Kyosho RB6 rear bumper (part # UM725), provides a rear bumper for added protection of the chassis, rear pivot, and trans case. NOT compatible with the 2018/2019 XB2.
To run the 1 down\in position in the suspension holders it is necessary to bevel the outer edges of the chassis for arm clearance. We find ourselves running the middle or upper positions so this has not been an issue for us thus far.
Also, if running the 1 up/in position, it is necessary to shave the bottom of the trans case for arm clearance- or purchase the updated 2018 trans case which is already relieved in the proper places.
Lastly, the J5D 7075 Narrow RR Suspension Holder will NOT fit the 2018 XB2 as the rear of the chassis has been narrowed and is does not support the hanger correctly due to the cutout for the rear bumper.
