The Powerflex Black Series rear differential mounts are a highly sought-after performance upgrade for road and track cars, offering unparalleled stiffness and response. Building on the success of their Yellow and Purple Shore 70A/80A ranges, Powerflex has introduced their new Black Series range, featuring an even more extreme compound designed specifically for the most demanding track use.
The Black Series bushes boast a staggering 25% increase in stiffness compared to the Purple Series, and up to 80% stiffer than stock rubber bushes. This means that the bushes will never be the weak link in your suspension setup, allowing every other component to perform exactly as intended without any compromise in performance due to worn bushes.
The Powerflex Black Series is optimized for extreme track use, utilizing their toughest Shore 95A compound. This results in unparalleled response and control, making it the perfect choice for those who demand the very best from their suspension setup.
It's worth noting that these are the stiffest bushes Powerflex produces, and should only be considered by those who require the most extreme level of stiffness. For more compliant options, please consider the Yellow and Purple ranges.
