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.

It’s practical, user-friendly, and tailored for law enforcement needs.
Format: Paperback
This book has been an absolute gem as I prepare to apply for a law enforcement job where Spanish is a required skill. It’s well-organized, easy to follow, and covers practical vocabulary and phrases that are directly relevant to real-world scenarios. Not only is it incredibly useful, but it’s also engaging and fun to use, making learning feel less like a chore. The structure allows me to focus on the most important phrases for law enforcement situations, and it’s already helping me feel more confident about communicating effectively in Spanish.

Focused and Relevant
Format: Paperback, Format: Paperback
I’m new to learning Spanish. I’ve been at it for only about 9 months, but I chose to learn it for my job as a 911 dispatcher. This book was recommended to me by my Spanish tutor who has a family member that is a cop. This book contains SO many job relevant words, phrases, and cultural tips that I am learning a ton! And the book breaks things down by type. For example, the “traffic” chapter is a little less relevant to me as a dispatcher because I won’t be doing traffic stops or field sobriety tests. But there are also sections dotted throughout the book that are very relevant to dispatcher phone interrogation. Very pleased with this book, now they just need to write one specifically FOR dispatch. :D
