This aluminium rear upper chassis link fitted with plastic end caps is an aftermarket direct-fit replacement for Axial Racing Yeti XL models, identified by model number YTL014RPN. It locates the upper arm on the rear suspension and helps maintain consistent arm position through compression and rebound cycles.
Installation is a straightforward swap: remove the original rear upper link, refit this unit using the same hinge pins and fasteners, and reassemble the rear linkage. The aluminium shaft increases torsional stiffness compared with stock plastic links while the plastic ends preserve the original pivot interfaces.
Tuning notes: swapping rear upper links is a common way to change roll center and fine tune suspension reaction. This aluminium-with-plastic-ends option gives more repeatable geometry under load while keeping some factory pivot compliance for predictable behaviour.
A practical upgrade for builders wanting improved repeatability at the rear without altering mounting geometry.
