Why is there a restocking fee?

Well the first reason is that it was in the terms and conditions on checkout. However there is a better reason.  Honest companies charge restocking fees for a very simple reason: to keep costs (and thus prices for you) down when dealing with the return of items that are not defective. There are a lot of costs associated with processing an order. If you buy something and then return it, there is more costs to handle the return.

All returns must be thoroughly inspected when received back at the warehouse to ensure they are in 100% resalable condition. New packaging materials usually need to be utilized because it is typically only designed to be used two times (initial use and possible return shipment). Time and materials involved inspecting, repackaging and restocking are not insignificant. The bottom line is restocking fees help keep prices low for you!  

For this reason we do not accept returns on any used or previously installed products. We will not sell used products to our customers who are expecting brand new Garagistic parts. At times we may have to charge a higher restocking fee on a return if the parts are damaged during the return shipping. It is your responsibility to ensure the safe arrival of the parts you are returning to us. Thanks!

 

E39 Non-M Sedan Polyurethane Rear Trailing Arm Bushings (RTAB) - 33321091335 / 33321091336 , 33326757315 / 33326757316

Description

The BMW E39, known for its balance of comfort, build quality, and excellent driving dynamics, continues to be a popular choice of mid-size sedan amongst driving enthusiasts. As these vehicles age, suspension components such as the rear trailing arm bushings (RTAB) — also referred to as rear lower swing arm bushings — often wear out, negatively affecting handling and ride quality. Replacing these with polyurethane bushings has become a common upgrade in recent years, offering several performance benefits over OEM rubber counterparts.

Why Upgrade to Polyurethane?

OEM rubber bushings are designed to absorb vibrations and allow controlled flex / toe-in under load. However, they degrade over time, leading to excessive and unwanted suspension movement, imprecise handling, and uneven tire wear. Polyurethane bushings, by contrast, provide greater stiffness and durability, which translates into:

  • Improved Handling Response: Firmer poly bushings reduce unwanted suspension flex, improving alignment stability during cornering and braking,

  • Longer Lifespan: Polyurethane resists cracking, rotting, and deformation over time much better than rubber, especially under performance driving conditions.

  • Better Road Feedback: Enthusiasts appreciate the more connected feel polyurethane bushings bring, enhancing driver confidence.

Replacing the E39's rear lower swing arm bushings with polyurethane is a cost-effective upgrade for those seeking sharper handling and longer-lasting suspension components. Whether you're restoring your daily driver back to its former glory, or building a more capable canyon carver, polyurethane RTABs are a great step towards improved performance.

Installation

Upgrading to polyurethane bushings requires pressing out the old rubber units and installing the new bushings — a task that can be done with a typical BMW bushing removal cup kit or a hydraulic press. The Garagistic Polyurethane E39 RTABs can be pressed or tapped into place when installing into the the swing arm bushing housings.

It’s important to lubricate polyurethane bushings properly with a silicone PTFE grease to prevent squeaking or unwanted noise. While polyurethane offers performance advantages, it does transmit more vibration and noise into the cabin compared to rubber. For a daily-driven E39, this trade-off is generally minimal with high-quality polyurethane, but it’s worth considering based on your comfort preference.
