HIHIAV Valve Cover Gasket Kit for Jeep 4.0L (1996–2006) VS50458R — Silicone Seal + 15 Grommets

HIHIAV VS50458R is a complete valve cover gasket kit engineered to restore a reliable, oil-tight seal for 4.0L Jeep engines (Cherokee, Grand Cherokee, Wrangler/TJ) from 1996–2006.

If your Jeep shows oil seepage around the valve cover or you’re performing routine maintenance, this kit provides the gasket and the necessary grommets to replace worn sealing components in one installation. Built from a high-quality silicone rubber compound, the set aims to resist oil and high under-hood temperatures while matching the original fitment for popular 4.0L Jeep applications.

Which Jeep models and years does this gasket fit?

This HIHIAV kit is compatible with a range of 4.0L Jeep engines across mid‑late 1990s and early 2000s models. It covers both Cherokees and Wranglers that share the same valve cover design, so you can use one part for multiple vehicles.

• 1996–2001 Jeep Cherokee (4.0L)
• 1996–2004 Jeep Grand Cherokee (4.0L)
• 1997–2006 Jeep Wrangler and Wrangler TJ (4.0L)
• OE/aftermarket cross-reference numbers included with the kit for identification

What components are included in the kit and why does that matter?

The package contains the valve cover gasket plus 15 grommets — everything needed to reseal the cover and replace brittle or damaged retainers. Receiving both gasket and grommets helps ensure a complete repair without sourcing small parts separately.

• 1 pre-shaped valve cover gasket sized for 4.0L Jeep valve covers
• 15 grommets to replace those that commonly crack with age
• Packaged in a protective bag and box to prevent damage or loss during shipping

How does this gasket match original equipment and cross-reference numbers?

HIHIAV supplies the gasket with multiple cross-reference numbers so you can confirm compatibility with factory and aftermarket lists. The part numbers align with commonly used OEM and replacement identifiers for the 4.0L valve cover assemblies.

• Cross-references: VS50458R, VS50266, VC1123G
• OEM-style numbers listed for verification against vehicle parts catalogs
• Intended to match the shape, bolt hole pattern, and sealing profile of the original gasket

How should I expect the kit to perform and what installation tips help ensure a good seal?

The silicone-based gasket is designed to resist oil and under-hood heat; pairing it with fresh grommets reduces the chance of future leaks from degraded retainers. For best results, clean the valve cover mating surface, inspect bolt threads, and tighten to the vehicle manufacturer’s torque sequence.

• Clean mating surfaces of old gasket residue and oil before installation
• Replace all grommets included to ensure uniform compression and sealing
• Tighten bolts incrementally and follow the correct torque and sequence

Who is this for: This kit is intended for DIY mechanics, independent shops, and Jeep owners with 4.0L engines who need a complete valve cover gasket and mounting grommet set for repairs or preventive maintenance. If you want to avoid sourcing multiple parts, prefer a silicone material over aged rubber, and need parts that reference common OEM numbers, this HIHIAV kit provides a ready-to-install solution. For any fitment questions, compare the cross-reference numbers to your vehicle’s parts list or contact an experienced technician.
