AAE Power Steering Pump Kit - BMW E82/88 135, E9X 335 (w/ Active Steering)

Product Details

In the E82 and E9x chassis, steering feedback is everything. Whether you're hitting the apex or navigating a tight paddock, an aging power steering pump introduces inconsistency and heat into the hydraulic circuit. The AAE 5801NKTB Kit is a technical-grade solution designed to restore consistent hydraulic pressure and eliminate the "dead" feel associated with failing factory pumps.

This kit addresses the critical failure points of the N51 and N52 hydraulic systems. By bundling a fresh reservoir, you ensure the internal filtration system is clean—preventing old metallic debris from scoring your new pump's internals. It is a precision-engineered, track-ready solution for drivers who refuse to compromise on front-end communication.
