As the load increases, the hollow rubber springs push back harder, which cuts sag, sway and body roll when you tow or haul without spoiling the unloaded ride. Rated at 8,600 lb per set, it comes with helper springs, brackets and hardware; total load must still stay within the vehicle's gross weight rating.\u003c\/p\u003e\u003ch3\u003eFits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1999-2018 Chevrolet Silverado 1500 — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2020-2021 Chevrolet Silverado 1500 — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2007 Chevrolet Silverado 1500 Classic — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2001-2003 Chevrolet Silverado 1500 HD — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2005-2006 Chevrolet Silverado 1500 HD — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2007 Chevrolet Silverado 1500 HD Classic — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2019 Chevrolet Silverado 1500 LD (old model) — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e1999-2018 GMC Sierra 1500 — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2020-2021 GMC Sierra 1500 — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2007 GMC Sierra 1500 Classic — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2001-2003 GMC Sierra 1500 HD — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2005-2006 GMC Sierra 1500 HD — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2007 GMC Sierra 1500 HD Classic — rear, RWD\/4WD\u003c\/li\u003e\n\u003cli\u003e2019 GMC Sierra 1500 Limited (old model) — rear, RWD\/4WD\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFitment is from the manufacturer's application data; check your year, cab, drivetrain and wheel setup before ordering.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEliminate suspension sag: when towing a heavy trailer, Timbren SES helps you avoid bottoming out and extends the life of your suspension\u003c\/li\u003e\n\u003cli\u003eControl trailer sway: stabilizes the vehicle with unbalanced loads, in crosswinds or when passing heavy trucks\u003c\/li\u003e\n\u003cli\u003eControl body roll: progressive-rate rubber springs resist lean in corners and add stability\u003c\/li\u003e\n\u003cli\u003eImprove the ride: Aeon® rubber springs absorb road shocks and bumps, so towing doesn't have to mean poor ride quality\u003c\/li\u003e\n\u003cli\u003eEconomical and trouble free\u003c\/li\u003e\n\u003cli\u003eSimple and easy to install\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Timbren\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e GMRCK15S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e SES helper spring kit (jounce spring)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad capacity:\u003c\/strong\u003e 8,600 lb per set (not to exceed vehicle gross weight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Set of 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring material:\u003c\/strong\u003e Aeon hollow rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting type:\u003c\/strong\u003e Frame mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Helper springs, brackets, hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting hardware included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated install time:\u003c\/strong\u003e 1 hour\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWarranty:\u003c\/strong\u003e Timbren limited lifetime warranty.\u003c\/p\u003e\u003cp\u003eGenuine Timbren.
