Review on National Seal 6818 Differential Pinion by Joseph Burnside

I recently upgraded my differential with a high-quality pinion from this brand and have been impressed with the results. The seal has held up through multiple high-speed runs without a leak. The only downside is that it`s slightly pricier than other options on the MARKET. Overall this is a must-have for any automotive enthusiast looking to enhance their vehicle's performance. .
