Overview

The Powerflex Rear Diff Front Mounting Bush is a high-performance polyurethane replacement for BMW F20, F21, F22, and F23 models. This Road Series bushing minimizes suspension flex to address imprecise handling, uneven tire wear, and braking instability common with aging rubber components.
Show original supplier description
The Powerflex Rear Diff Front Mounting Bush is a performance-engineered polyurethane replacement designed to replace original rubber bushings in BMW F20, F21, F22, and F23 models, including M140i, M135i, M235i, and M240i trims. By replacing factory-installed rubber with durable, precision-engineered polyurethane, this kit significantly reduces unwanted differential movement, directly countering issues like imprecise handling, uneven tire wear, and braking instability under load. As part of the Powerflex Road Series, this product is specifically formulated for standard and fast road use, offering improved road grip and chassis response without the harshness often associated with harder track-only components. Each set includes two bushings and is engineered to provide a direct-fit improvement over OEM part number 33176760287. This product is backed by a lifetime warranty from Powerflex.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
