This aluminium rear upper chassis link with plastic end caps is a direct-replacement part for Axial Racing Yeti XL vehicles, sold under model YTL014RPN. It secures the rear upper arm location and helps keep consistent geometry when the suspension compresses and rebounds.
Fitting is simple: remove the stock rear upper link, position this unit, and refit using the existing hinge pins and hardware. The aluminium centre section reduces flex versus full-plastic links while the polymer ends retain the factory pivot feel.
Tuning tip: swapping the rear upper link is a practical way to adjust roll centre and sharpen suspension response. This hybrid design gives steadier geometry under load without losing original pivot characteristics.
A sensible upgrade for trail and crawl setups where more consistent arm location is helpful but factory pivot feel is wanted.
