Powerflex PFR36-407 Rear Link Arm Inner Bushes - Position 7
Replacement Powerflex rear link arm inner bushes for Mazda MX-5 MK3 / MK3.5 / MK3.75 NC (2005-2015) models listed in the compatibility table. This part is shown as position 7 on the Powerflex suspension bush diagram.
These polyurethane bushes are fitted to the inner mounting points of the rear suspension link arms, helping reduce unwanted movement and maintain more consistent rear suspension geometry. They are designed as aftermarket replacements for the original rubber components.
Two bushes are required per vehicle, with one used on each side of the rear suspension. This Powerflex kit supplies both bushes required for one vehicle.
Ageing original rubber bushes can soften, split or deteriorate over time, allowing additional suspension movement. Typical symptoms can include reduced rear-end precision, inconsistent alignment under load, uneven tyre wear or knocking from the rear suspension.
