New Ultra Pro Magnumª Rockers are made from investment-cast 8650 chromemoly steel, utilize upgraded trunnions and needle bearings over stock and are stronger, stiffer and more durable than the stock parts. They also feature a 1.8 ratio (compared to the stock rockersÕ 1.7) and utilize a roller tip instead of a slider. The higher ratio and increased stiffness make these rockers a great option for increasing lift without changing cams. This increased stiffness, along with the upgraded trunnion package and roller wheel, also makes them a perfect choice when running aftermarket valve springs. The rockers are also available in a bolt-on design that uses stock rocker stands. The stud-mount version is perfect for individuals running mechanical lifters as well. Kits do not include pushrods, but they are available separately.Increased (1.8) Ratio & Stiffness Make Rockers a Great Option for Increasing Lift w/o Changing CamsInvestment-Cast 8650 Chromemoly Steel Body That is Stronger, Stiffer & More Durable Than StockÊIncreased Stiffness, Upgraded Trunnion & Roller Wheel Make Rockers Perfect for Aftermarket Valve SpringsLimited Lifetime Warranty: So Strong That We Guarantee the Rocker Bodies Against Breakage for LifeStud-Mount DesignÊConverts GM LS to Convenient, Adjustable Valve Train; Bolt-On Version AvailableALSO AVAILABLE FOR LS1/LS2/LS6/4.8/5.3/6.0/Cathedral-Port Head Equipped LS ApplicationsÊAll Available Ultra Pro Magnumª GM LS RockersÊLS3/L92/L76 - RectangleÊPort HeadsÊUltra Pro Magnumª GM LS Rockers (16) - Bolt-OnÊUltra Pro Magnumª GM LS RockersÊ(16) - Stud MountÊUltra Pro Magnumª GM LS Rockers (16) - Stud Mount Kit w/ Studs & Guide Plates ÊLS1/LS2/LS6 - Cathedral Port HeadsÊUltra Pro Magnumª GM LS RockersÊ(16) - Bolt-OnÊUltra Pro Magnumª GM LS RockersÊ(16) -ÊStud MountÊUltra Pro Magnumª GM LS Rockers (16) - Stud Mount Kit w/ Studs & Guide PlatesÊ*Guide plates require chromemoly pushrods.
