1. FZJDSD Timing Chain Kit for Infiniti/Nissan VQ37VHR 3.7L

Best Overall

A complete aftermarket timing chain kit designed to replace the factory timing components on 3.7L VQ37VHR Infiniti and Nissan engines.

This timing chain kit supplies the full set of wear items needed when servicing the VQ37VHR 3.7L engine used in G37 and related Infiniti models. It includes upper and lower timing chains, cam and crank gears, multiple hydraulic tensioners and guide rails so a technician can replace the entire timing system in one job rather than swapping single parts. The components are marketed as tested and inspected, and the kit’s comprehensive contents reduce the risk of leaving worn parts in place during a timing service. In practice buyers should expect to install all included pieces during an engine timing overhaul; having the full kit simplifies labor and ensures mating parts match. Limitations are typical for aftermarket timing kits: fitment must be confirmed against the vehicle before purchase and long-term durability depends on installation quality and maintenance. For owners wanting a complete, ready-to-install replacement set for a VQ37VHR timing overhaul, this kit covers the common service items.

Best for: Balanced owners who want a single comprehensive timing kit to perform a proper VQ37VHR timing overhaul without sourcing individual components separately.

Less Ideal for: Those who prefer factory-branded replacement parts or who are unsure about exact engine variant should consider a factory-quality kit or verify fitment before buying.

Verdict: A one-stop aftermarket timing chain kit that supplies all the parts needed to service the VQ37VHR 3.7L timing system on Infiniti G37 and related models.

2. ApplianPar Engine Timing Chain Kit for Nissan 370Z and Infiniti Models

Best Quality

A complete timing chain kit designed to replace worn components on select Nissan 370Z and Infiniti VQ-series engines.

This ApplianPar timing chain kit supplies the core components needed when servicing VQ-series engines in selected Infiniti and Nissan 370Z applications. It is intended for full-timing replacement during an engine overhaul or preventive maintenance and includes chains, guides, and associated parts to restore timing drive function. In hands-on use the pieces appear well machined and fitment checks in customer reports indicate close match to factory parts, which simplifies installation and timing alignment. The kit is practical for enthusiasts and shops wanting a single-purchase, vehicle-specific solution rather than sourcing individual components. Expect a relatively complete set that reduces downtime versus ordering OEM parts separately, but professional installation is recommended because correct timing setup and torque procedures are critical. This kit does not supply ancillary gaskets or fluids, so plan to source seals and lubricants separately for a fully sealed service.

Best for: Performance-oriented owners and independent shops working on Infiniti G37 and related VQ engines who prioritize restoring precise timing performance with a vehicle-specific kit.

Less Ideal for: DIYers looking for a plug-and-play OEM-equivalent package without additional seals or fluids, or owners who prefer factory-branded parts only.

Verdict: A vehicle-specific timing chain kit that offers quality-machined components to restore timing drive function on VQ engines without sourcing parts individually.

3. YA-MAYPAY Timing Chain Kit for Nissan/Infiniti VQ37VHR 3.7L

Best Value

A complete timing chain kit that replaces the chain, sprockets, guides, and tensioners for VQ37VHR 3.7L engines used in select Infiniti and Nissan models.

This YA-MAYPAY timing chain kit supplies the major components needed to rebuild the VQ37VHR timing system: primary chain, two cam chains, cam and crank sprockets, multiple tensioners, and several guides. It is intended for an in‑engine timing system service where the factory chain components show wear or when performing a mileage-based overhaul.

Because the kit groups all wear items, it streamlines parts sourcing for a single repair and can save time compared with buying pieces separately. Important limitations are typical of aftermarket kits: fitment is specific to VQ37VHR engines so installation requires engine disassembly and accurate timing setup, and buyer support or long-term durability may vary compared with factory parts. For a practical optimizer looking to refresh an Infiniti G37 timing system affordably, this kit covers the usual failure points without unnecessary extras.

Best for: Practical optimizers who prioritize getting a full, affordable timing-system refresh for their Infiniti G37 without overpaying for dealer parts and who are comfortable coordinating a shop-level repair.

Less Ideal for: Owners seeking factory-direct parts coverage, extended manufacturer-backed warranties, or those who prefer dealer installation and support should consider alternatives.

Verdict: A budget-conscious, all-in-one timing chain kit that supplies the common wear parts needed to refresh the VQ37VHR timing system.

4. YOMALL Timing Chain Kit with Tensioners and Guides for 3.7L VQ37VHR (Fits Infiniti G37 / 370Z / Q50/Q60/Q70)

Practical benefits include getting all the core replacement parts in one purchase and avoiding piecemeal sourcing of components. Important limitations are that it does not include timing cover gaskets or other ancillary seals, and timing work requires proper tools and professional-level installation to avoid engine damage. For budget-focused repairs it offers strong value, but long-term durability depends on correct installation and maintenance.

Best for: Budget-conscious owners or independent mechanics who prioritize a full, lower-cost timing system rebuild for 3.7L VQ37VHR engines and want a single kit to replace worn chains, guides, and tensioners.

Less Ideal for: Those seeking an OEM-branded kit with factory packaging or installers who prefer a kit that includes every gasket and accessory needed for a complete timing cover service should consider alternatives.

Verdict: A cost-effective, full timing chain kit that bundles the chains, tensioners, and guides needed to restore timing function on 3.7L VQ37VHR engines.

5. Autodevil Timing Chain Kit for Infiniti G37 3.7L (fitment 2008–2013)

For a reliability-focused G37 owner this kit offers a practical, lower-cost way to restore correct timing with components that match OEM part numbers.

Best for: Reliability-focused Infiniti G37 owners who prioritize restoring proper timing with a complete aftermarket kit and who are comfortable using a shop or hiring a qualified technician for engine-level work.

Less Ideal for: Owners who want strictly factory-branded parts or who expect plug-and-play installation without engine disassembly should consider dealer-sourced alternatives or professional installation plans.

Verdict: A practical, reliability-oriented full timing kit for the G37 3.7L that matches OEM part numbers and simplifies a comprehensive timing service, provided you use proper installation procedures.
