Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag, and help stabilize the load.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEliminate Vehicle Squatting And Sagging\u003c\/li\u003e\n\u003cli\u003eCushion Road Shocks\u003c\/li\u003e\n\u003cli\u003eImproves Handling\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty\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 PF357\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Jounce Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity:\u003c\/strong\u003e 20000 Pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Air Compressor:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Set Of 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range:\u003c\/strong\u003e Not Applicable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Frame Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Bellows:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Air Line:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Roll Plate:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Valve:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Type:\u003c\/strong\u003e Not Applicable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWith Mounting Hardware:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated Install Time (Hours):\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Timbren, shipped from our warehouse in Upland, California.
