Rather than replacing the factory rubber bushings entirely, these precision spacers work alongside them — limiting left and right deflection of the trailing arm bushing under load to suppress abnormal rear beam angle variation, reduce tyre wear, and sharpen cornering response. The 85A durometer polyurethane delivers a low NVH impact, maintaining the comfort characteristics of the factory rubber while meaningfully improving suspension geometry stability under hard cornering, track use, or spirited mountain road driving.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e85A durometer polyurethane construction delivers effective NVH suppression alongside improved durability compared to standard rubber\u003c\/li\u003e\n\u003cli\u003eLimits left and right trailing arm bushing deflection under load – reduces abnormal rear beam angle variation for more consistent suspension geometry\u003c\/li\u003e\n\u003cli\u003eReduces rubber torsion on the factory bushing – extending its service life rather than replacing it\u003c\/li\u003e\n\u003cli\u003eImproves cornering precision and road feel feedback while maintaining factory ride comfort characteristics\u003c\/li\u003e\n\u003cli\u003eLow NVH impact – suitable for daily street driving as well as track and mountain road use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCondition: 100% Brand New\u003c\/li\u003e\n\u003cli\u003eType: Rear Trailing Arm Bushing Limit Spacers\u003c\/li\u003e\n\u003cli\u003eMaterial: Polyurethane\u003c\/li\u003e\n\u003cli\u003eBushing Hardness: 85A Shore\u003c\/li\u003e\n\u003cli\u003eMounting Position: Rear Trailing Arm\u003c\/li\u003e\n\u003cli\u003eNVH Impact: Low – will increase steering wheel feedback and road surface transfer\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Street · Track · Mountain Road\u003c\/li\u003e\n\u003cli\u003eItem Weight: 0.119 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eFitment:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eBMW 3 Series E36 (1992–1999) – excluding Ti and Z3 variants\u003c\/li\u003e\n\u003cli\u003eBMW 3 Series E46 (1999–2005) – excluding Ti variants\u003c\/li\u003e\n\u003cli\u003eBMW X3 E83 (2004–2010)\u003c\/li\u003e\n\u003cli\u003eBMW Z4 E85 · E86 (2003–2008) – excluding Z4M variant\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eContents:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e1x Set Rear Trailing Arm Bushing Limit Spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eBenefits:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCorrects abnormal rear beam angle variation caused by excessive trailing arm bushing deflection under load\u003c\/li\u003e\n\u003cli\u003eReduces tyre wear associated with inconsistent rear suspension geometry during cornering\u003c\/li\u003e\n\u003cli\u003eExtends factory rubber bushing service life by reducing torsional stress on the bushing during dynamic loading\u003c\/li\u003e\n\u003cli\u003eMaintains stable suspension geometry under severe road conditions for more predictable and precise handling\u003c\/li\u003e\n\u003cli\u003eLow NVH increase makes this a practical upgrade for comfort-oriented daily drivers as well as performance builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eInstallation Notes:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003ePolyurethane spacers must be greased during installation – do not install dry\u003c\/li\u003e\n\u003cli\u003eIf the original factory rubber bushing cover is already badly damaged, the rubber cover must be replaced before fitting these spacers\u003c\/li\u003e\n\u003cli\u003eNot compatible with polyurethane, Delrin, or monoball rear trailing arm bushings – for use with factory rubber bushings only\u003c\/li\u003e\n\u003cli\u003eNot compatible with adjustable rear trailing arm brackets\u003c\/li\u003e\n\u003cli\u003eFor optimal suspension performance, pairing with M3 bearings (part number 33 32 6 770 817) is recommended\u003c\/li\u003e\n\u003cli\u003eNot compatible with BMW E36 Ti, E36 Z3, E46 Ti, or Z4M variants\u003c\/li\u003e\n\u003cli\u003eIf unsure about compatibility with your specific build or bushing setup, contact our team before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eWarranty:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e12-month standard warranty from date of purchase\u003c\/li\u003e\n\u003cli\u003eContact our support team for assistance with any issues\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K2 Industries","offers":[{"title":"Default Title","offer_id":54604439126321,"sku":"1005009562896888","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0813\/5727\/5441\/files\/S7c7cb48e27794324a2e9e5566e0d0501e.webp?v=1781489143","url":"https:\/\/acmtechnik.com\/products\/bmw-3-series-e36-e46-x3-e83-z4-e85-e86-85a-polyurethane-rear-trailing-arm-bushing-limit-spacers-1992-2010","provider":"ACM Technik LLC","version":"1.0","type":"link"}
