Adjustments and modifications to the engine can cause a risk of leaks, especially when gas or fluid pressures increase – so having the correct 2014-2017 gaskets & seals for your GMC Sierra is an important part of certain upgrades. Working on the cylinder heads of your truck so that they won’t leak the increased pressures of a powered-up engine, for example, means that stronger head gaskets are useful and maybe crucial. The 2007-2013 gaskets & seals carried by AmericanTrucks includes head gaskets made from steel with fluoroelastomer semi-rubber coating that can endure boosted pressures, plus temperatures up to 482° F. Oil pump installation kits also include upgraded gaskets to contain the bigger pressures and make sure they do their job – all using parts made to high quality standards by leading aftermarket companies.
