This aluminium rear suspension mount is an optional RC part for the 4WD YZ-4 series, designed specifically for the L5 suspension arm. The rear-side suspension pin spacing is 2mm narrower than the stock rear mount, producing a subtle change to rear geometry without altering the arm itself.
When installed as a set with the front-side mount Z4-300LRF and the slightly longer L5 arm Z4-008RS5, the setup permits track width adjustment while keeping the longer arm length. On high-grip surfaces such as carpet or artificial turf the mount helps create modest chassis roll even with stiffer suspension, aiding turn-in performance.
For balancing front and rear behavior you can also fit the 1mm longer front arm Z4-008F1 to refine weight transfer and entry behavior. The description applies to RC-scale components and setup choices only.
