Powerflex Rear Subframe Mounting Insert Set - 335i 2006+

Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension for better handling, driver feedback, and tire wear. Powerflex uses premium polyurethane materials for minimal NVH (noise, vibration, harshness) and increased longevity over the stock rubber bushings. The quality of Powerflex products can be seen the moment you open the box: premium polyurethane, detailed moldings, lube holding grooves and knurls, and 304 stainless sleeves. Each kit is supplied with a copper-based grease for extended squeak-free operation. In many applications (if noted in diagram), we have polyurethane engine/drivetrain mounts and reinforcements to reduce movement for better throttle response and more power to the wheels.

Powerflex bushings do not come in complete chassis kits. Our bushings come à la carte to fit each customer's needs. An automobile's bushings and mounts wear at different rates making "complete-kit" bushing sets unnecessary for many car owners. Replacing only the "weak links" in your car's suspension is a great way to tighten handling without stressing the budget. Bushings come in pre-determined durometers (measured hardness) engineered to reduce bushing deflection while keeping NVH to an absolute minimum. Some locations have an optional stiffer durometer material for an even higher level of performance and feedback. Please contact us for custom durometer applications.

Powerflex copper-based grease is supplied with every dynamic product. We suggest using only a copper-based grease for lubrication. Due to grooves and knurls cast into the material to hold the lubricant, bushings will rarely need re-lubing. We do not suggest using an "anti-seize" product for lubrication.
