H\u0026amp;R's DRM (Dual Ring Mount) design provides full hub-centric contact at both the wheel hub and the wheel center bore, distributing load forces evenly just as the factory hub does. This eliminates the vibration and imbalance risks associated with lug-centric spacers. The HRS3085738 is machined from H\u0026amp;R's proprietary aluminum alloy, which has a higher tensile strength than standard 6061-T6 billet, and includes the necessary hardware for a complete installation. Adding 15mm per side widens the track for a more aggressive stance and improved cornering stability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eHubcentric DRM design with full hub contact for safe, vibration-free installation\u003c\/li\u003e\n\u003cli\u003e15mm spacer width per side (30mm total track increase per axle)\u003c\/li\u003e\n\u003cli\u003e5x120.65 bolt pattern for GM and Chevrolet performance platforms\u003c\/li\u003e\n\u003cli\u003e73.8mm center bore machined to match factory hub diameter\u003c\/li\u003e\n\u003cli\u003e1\/2\" UNF stud thread for correct wheel bolt engagement\u003c\/li\u003e\n\u003cli\u003eProprietary H\u0026amp;R alloy with higher tensile strength than 6061-T6\u003c\/li\u003e\n\u003cli\u003eTUV-approved engineering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eHRS3085738\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPN\u003c\/td\u003e\n\u003ctd\u003eHRS3085738\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpacer Width\u003c\/td\u003e\n\u003ctd\u003e15mm per side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrack Widening (per axle)\u003c\/td\u003e\n\u003ctd\u003e30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBolt Pattern\u003c\/td\u003e\n\u003ctd\u003e5x120.65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter Bore\u003c\/td\u003e\n\u003ctd\u003e73.8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStud Thread\u003c\/td\u003e\n\u003ctd\u003e1\/2\" UNF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eProprietary H\u0026amp;R Aluminum Alloy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDRM Hubcentric Wheel Adaptor\/Spacer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eSet of 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eH\u0026amp;R Springs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eNot specified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2x H\u0026amp;R HRS3085738 Trak+ 15mm DRM hubcentric wheel spacers\u003c\/li\u003e\n\u003cli\u003eRequired mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout H\u0026amp;R Springs\u003c\/h4\u003e\n\u003cp\u003eH\u0026amp;R Springs is a German manufacturer with over 40 years of experience producing suspension and wheel fitment components for both OEM and aftermarket applications.
