Each assembly combines a durable aluminum spacer and a flexible rubber grommet to cushion the bolt, maintain torque, and lower the risk of cracking or stripping the valve cover when tightening. The parts are vehicle-specific fit components intended for truck and light-truck LS engines and are sold new as an eight-piece set.\u003c\/p\u003e\n\n\u003ch3\u003eWhich engines and model years are these grommets compatible with?\u003c\/h3\u003e\n\u003cp\u003eThese valve cover bolt assemblies are compatible with most GM LS-family engines produced from the late 1990s through the mid-2010s.

That spacing prevents bolts from bottoming out and transferring excessive force, which is a common cause of cover cracks and stripped threads.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum spacer prevents bolt over-travel into the cover\u003c\/li\u003e\n  \u003cli\u003eRubber grommet cushions vibration and seals around the bolt\u003c\/li\u003e\n  \u003cli\u003eUniform length helps maintain consistent torque across all bolts\u003c\/li\u003e\n  \u003cli\u003eSold as a matched set of eight for even installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction details should I expect?\u003c\/h3\u003e\n\u003cp\u003eThe assemblies pair a lightweight aluminum spacer with a resilient rubber grommet to balance strength and sealing. The metals resist deformation under torque while the rubber helps isolate engine vibration and form a snug seal around the bolt shank.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum spacer for structural support and anti-bottoming\u003c\/li\u003e\n  \u003cli\u003eRubber grommet for sealing and vibration damping\u003c\/li\u003e\n  \u003cli\u003ePrecision fit for vehicle-specific LS valve cover holes\u003c\/li\u003e\n  \u003cli\u003eSold new in an 8-piece package for one cover set\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I install these myself, and what should I watch for?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable removing a valve cover and re-torquing bolts to factory specifications. Use a torque wrench and follow the engine manufacturer's torque sequence to avoid uneven pressure; the spacers help, but proper torque values are still essential.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRemove old grommets and clean the bolt holes before fitting\u003c\/li\u003e\n  \u003cli\u003eInstall each assembly and tighten to OEM torque specs in sequence\u003c\/li\u003e\n  \u003cli\u003eDo not use on early perimeter-bolt LS covers—verify fit first\u003c\/li\u003e\n  \u003cli\u003eCheck for leaks after initial run and retorque if recommended\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This Jetuplusllc 8-piece valve cover bolt grommet and crush sleeve kit is aimed at DIY mechanics, professional technicians, and restorers working on Chevrolet LS-series truck and performance engines from roughly 1997–2014 who want a reliable, vehicle-specific solution to prevent valve cover damage during installation. If you maintain or rebuild LS engines and need consistent bolt spacing and improved seal\/vibration control, this set offers a direct-fit replacement. Confirm your valve cover type (perimeter vs. center-bolt) before ordering to ensure compatibility.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these grommets fit all Chevrolet LS engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They fit most LS-series engines 1997–2014 listed (including 4.8L–6.2L variants) but do not fit early perimeter-bolt LS valve covers from certain 1997–1998 models.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these easy to install at home?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
