Valve springs are an essential upgrade that are often overlooked in many performance builds. The factory valve springs in your engine are not intended to handle the increased engine RPM and elevated boost levels that are typical in modified applications. Even common upgrades like an aftermarket turbocharger and performance tuning can cause valve float that may result in serious engine damage. In addition, your valves can be blown open by boost and drive pressure causing reversion. Reversion is when exhaust gasses flow backwards and enter the cylinder on the intake stroke, hurting your engine performance. This is why upgraded valve springs are a must-have on modified engines! \u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003eThe XDP XD313 Valve Springs feature a conical design that provides more valve control than a standard straight spring. The conical shape allows for a smaller and lighter spring retainer that is also stronger due to size reduction. Unlike other valve springs on the market, the XD313 Valve Spring Kit can be used on a wide range of trucks, from stock all the way up to competition builds making 2,000 HP. This makes them a perfect choice for a \"one-and-done\" upgrade that lets you modify your engine to support more power down the road. Each spring is computer load mapped and then matched within 1 lb of seat pressure followed by a stress relief process to ensure quality and long-term reliability. Each set comes complete with springs, locks, retainers, and is backed by XDP's 1 year unlimited mileage warranty.\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/div\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\n\u003ch5 data-mce-fragment=\"1\"\u003eFEATURES: \u003c\/h5\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e100 Lb.
