Mazda's CX-5 and it's larger sibling, the CX-9, have been regarded as some of the best small and mid-sized SUVs on the market - and on top of that have proven to maintain Mazda's record of outstanding reliability...... with a few small exceptions. Among those exceptions is the center rear differential mount. Fast-wearing and the source of unwanted noise, harshness and unchecked movement these OEM bushings have proven to live short lives. Making matters worse, they are only available from Mazda as part of the complete rear subframe making for incredibly costly out-of-warranty repairs and unfortunately, one you may be subjected to more than once if you're a long term owner. Based on feedback and demand from Mazda dealers worldwide SuperPro has developed and released a lifetime replacement option at a far lower cost; our SPF5108K. Maintaining new car levels of comfort and isolation our bushing design does not degrade or fail like the factory design; this is a true 'fix it once' solution warrantied for life - not matter how long your Mazda is on the road.
