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.\u003c\/p\u003e\n\u003ch3 data-end=\"765\" data-start=\"733\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eWhy Upgrade to Polyurethane?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp data-end=\"1076\" data-start=\"767\"\u003eOEM 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:\u003c\/p\u003e\n\u003cul data-end=\"1506\" data-start=\"1078\"\u003e\n\u003cli data-end=\"1220\" data-start=\"1078\"\u003e\n\u003cp data-end=\"1220\" data-start=\"1080\"\u003e\u003cstrong data-end=\"1110\" data-start=\"1080\"\u003eImproved Handling Response\u003c\/strong\u003e: Firmer poly bushings reduce unwanted suspension flex, improving alignment stability during cornering and braking,\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1373\" data-start=\"1221\"\u003e\n\u003cp data-end=\"1373\" data-start=\"1223\"\u003e\u003cstrong data-end=\"1242\" data-start=\"1223\"\u003eLonger Lifespan\u003c\/strong\u003e: Polyurethane resists cracking, rotting, and deformation over time much better than rubber, especially under performance driving conditions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"1506\" data-start=\"1374\"\u003e\n\u003cp data-end=\"1506\" data-start=\"1376\"\u003e\u003cstrong data-end=\"1400\" data-start=\"1376\"\u003eBetter Road Feedback\u003c\/strong\u003e: Enthusiasts appreciate the more connected feel polyurethane bushings bring, enhancing driver confidence.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eReplacing 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.\u003c\/p\u003e\n\u003ch3 data-end=\"1539\" data-start=\"1508\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eInstallation\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp data-end=\"1874\" data-start=\"1541\"\u003eUpgrading 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.\u003c\/p\u003e\n\u003cp data-end=\"2106\" data-start=\"1876\"\u003eIt’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.\u003c\/p\u003e\n\u003ch3 data-end=\"2106\" data-start=\"1876\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eFitment\u003c\/span\u003e\u003c\/h3\u003e\n\u003ch5\u003e\u003cem\u003eWILL THESE POLYURETHANE TRAILING ARM BUSHINGS FIT ON MY E39?\u003c\/em\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e All E39 Non-M Sedan Models (525i, 528i, 530i, 540i)\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement\u003c\/strong\u003e for BMW part no. \u003cem\u003e\u003cstrong\u003e33321091335 \/ 33321091336 \u0026amp; 33326757315 \/ 33326757316\u003c\/strong\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e The following E39 models below will fit with modification:\n\u003cul\u003e\n\u003cli\u003eE39 Wagon Models (528i Touring, 540i Touring) will need to drill out the rear bushing to M14\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003eSwing Arm OEM part #'s  \u003cem\u003e\u003cstrong\u003e33321093723 \u003c\/strong\u003e\u003c\/em\u003e, \u003cem\u003e\u003cstrong\u003e33321093724\u003c\/strong\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eE39 M5 Models will need to drill out the rear bushing to M14\n\u003cul\u003e\n\u003cli\u003eSwing Arm OEM part #'s \u003cem\u003e\u003cstrong\u003e33322229515 \u003c\/strong\u003e\u003c\/em\u003e, \u003cem\u003e\u003cstrong\u003e33322229516\u003c\/strong\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline;\"\u003eIncluded\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOne kit (4pcs) is required per car, no need to order front \u0026amp; rear bushings separately\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThese bushings are an 80A durometer polyurethane\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLifetime Warranty Guarantee\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWe stand by our products 100%.
