SPL Solid Differential Bushings - Nissan 370Z / Z / Infiniti G37

SPL Parts solid differential mounting bushings (SDBS) for the 2009+ Nissan 370Z and Z, plus 2007-2013 Infiniti G35/G37. They replace the soft stock silicone-filled bushings, notorious for tearing under hard driving, to hold the differential solidly to the subframe. This cuts diff "bounce" under launches, reduces wheel hop, protects the driveshaft and half shafts, and improves power transfer. CNC machined from 6061-T6 billet aluminum; bushing driver tool included. Made in the USA.
