Powerflex Rear Beam Bushes (PFR50-610) are polyurethane rear mounting bushings for Peugeot, Vauxhall, and Citroen vehicles. Made in the UK, these purple (80 hardness) bushes fit models with OE part numbers 5131.
These bushes are excellent and certainly tighten up the suspension. They are far superior to the OEM replacements on the market. I have used Powerflex before on another of my vehicles and the bushes transformed the handling. They are an excellent product at an excellent price. Thoroughly recommended.
