Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension which improves handling, driver feedback, and tire wear. Powerflex uses their own premium polyurethane formulation to provide minimal NVH (noise, vibration, harshness) and increased longevity over stock rubber bushings.
Bushings are produced in one of three durometers – Yellow (70A, approximately 25% stiffer than stock), Purple (80A, approximately 30% stiffer than stock), and Black (95A, approximately 80% stiffer than stock). Unlike other brands using only one urethane grade for all applications, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each location while minimizing unwanted NVH.
Powerflex urethane hardness is standardized per fitment and location. This takes out the guess work, so when you choose Street, you know our design engineers have selected the optimal polyurethane hardness for your specific application. Select parts are also available in an optional stiffer urethane (Black Series) for track and autocross performance where NVH is less important.

Great Supplements. Good prices. Made in the USA
Size: 90 Count (Pack of 1)
I love this company for all my supplement needs. My only complaint about the magnesium supplement is that the capsules are pretty large. If you have a problem swallowing pills/capsules you may have a bit of trouble swallowing these. However, I’ve never had magnesium that was easy to swallow. Most of Pure Supplements are small and very easy to swallow. The magnesium is the exception. All magnesium pills are large.
