zuverlass 2.4L Timing Chain Kit for GM Ecotec 2011–2017 — complete set with sprockets, guides and corrosion‑resistant parts

zuverlass 2.4 Timing Chain Kit is a complete replacement set engineered to restore correct valve timing on GM Ecotec 2.4L and compatible 2.2L engines used across Equinox, Terrain, Buick, Chevy and select Pontiac models.

If your vehicle is one of the GM models that use the Ecotec 2.4L (and some 2.2L) powertrains from 2009–2017, this timing chain kit supplies the core components needed for a professional-quality timing job. The kit groups all major wear items—chain, sprockets, guides, tensioners and related hardware—so you replace interacting parts at once rather than swapping only a worn chain. The components are manufactured with corrosion-resistant treatments and high-precision forging to ease installation and help maintain alignment under operating loads.

Which vehicles and engines will this kit fit?

This zuverlass timing kit is designed for GM Ecotec 2.4L L4 engines primarily from model years 2011–2017, and certain 2.2L applications listed by OEM cross-reference numbers. Always confirm fitment against your VIN or the vehicle compatibility tool before purchase.

• Primary fitment: Chevy Equinox and GMC Terrain L4 2.4L (2011–2017).
• Also compatible with: Buick LaCrosse, Regal, Verano (2011–2017 variants depending on engine) and Chevy Malibu, Impala, Captiva Sport, Orlando.
• Includes cross-references for part numbers like 12621505 and 9-4201s—verify against your OEM numbers.

What parts are included and why replace them together?

The kit contains all the interacting timing components so a single service addresses wear that affects timing accuracy. Replacing chain, sprockets, guides and tensioners together helps prevent early failure of new parts due to worn mating components.

• Included: timing chain, two right sprockets (12621505), upper and left guides/dampers, right tensioner arm, right upper tensioner, outer crank sprocket, and a timing gear oiler.
• Replacing all items together reduces the chance of misalignment or premature wear after service.
• Kit parts are treated for corrosion resistance and precision-forged for fit and durability.

How difficult is installation and what should mechanics know?

Installation requires intermediate to advanced mechanical skill and proper timing tools. Follow factory service procedures for locking the crank and camshafts, torque specifications, and tensioner preload sequence to ensure correct timing and avoid engine damage.

• Use OEM repair manual steps for cam/crank locking and timing chain tensioning.
• Inspect related items (cam seals, crank seal, oil pump) while the front cover is removed.
• Check that the two sprockets labeled 12621505 are correct for your engine—they are identical in this kit.

What are the product’s construction and quality highlights?

zuverlass emphasizes manufacturing precision and durable surface treatments in this kit. Components undergo high-precision forging and corrosion-resistant finishing to deliver consistent fitment and to resist typical engine operating stresses.

• High-precision forged sprockets and components for accurate tooth engagement.
• Corrosion-resistant treatment to extend service life in varied environments.
• Complete set approach minimizes risk of mismatched wear between old and new parts.

Who is this for: This zuverlass timing chain kit is intended for professional mechanics and experienced DIYers working on GM Ecotec 2.4L applications (and compatible 2.2L variants) who want a comprehensive parts set for a timing overhaul. If you need to replace one timing component, prefer to service the full assembly at once, or are rebuilding an engine, this kit provides the core items required for a correct timing system installation. Always confirm vehicle compatibility and part cross-reference numbers before ordering.
