zuverlass 2.4L Ecotec Timing Chain Kit 9-4201S – Complete kit with sprockets & tensioners for GM 2011–2017

Complete zuverlass 2.4L Ecotec timing chain kit (9-4201S) - a full replacement set of chain, sprockets, guides and tensioners engineered to restore valve timing on compatible GM 2.4L and some 2.2L engines.

If your GMC Terrain, Chevy Equinox, Buick Regal/LaCrosse/Verano, Malibu, Impala, Captiva Sport, Orlando, HHR, Cobalt or Pontiac G5 with the 2.4L (and certain 2.2L) Ecotec engines needs a timing system overhaul, this zuverlass kit supplies the major wearable components in one boxed solution. The kit replicates OE fitment for the 9-4201S/12621505 assembly and includes two identical right sprockets, the main timing chain, guides, tensioner arms, crank sprocket and oiling gear, all finished with corrosion-resistant treatments to improve longevity and ease installation.

Which vehicles and engine codes does this timing kit fit?

This kit is designed for a range of GM models using the 2.4L Ecotec engine across model years primarily from 2011–2017, plus selected 2.2L applications. Always cross-check part reference numbers and the vehicle compatibility tool before ordering to confirm fit.

• Common fits: GMC Terrain and Chevy Equinox L4 2.4L (2011–2017)
• Buick: Regal, LaCrosse, Verano (2012–2017 depending on model)
• Chevy: Malibu and Impala 2.4L (2013–2014 / 2014), Captiva Sport and Orlando 2.4L
• Selected 2.2L fits: Cobalt, HHR, Pontiac G5 (2009–2010 era) — verify part numbers

What components are included and how do they compare to OE parts?

The zuverlass 9-4201S kit contains the major wearing parts required for a timing chain job. Components are manufactured with high-precision forging and corrosion-resistant finishes to mirror OE durability and make installation straightforward for experienced technicians.

• Included: 2x right sprockets (12621505), 1x timing chain (12635048)
• Guides/dampers: upper and left timing chain guides (12588387, 13104978)
• Tensioning: right tensioner arm and right upper timing chain tensioner (24449448, 12608580)
• Additional: outer crank sprocket (24424758) and timing gear oiler (12577163)

How will this kit affect installation and engine service life?

Replacing worn chains, sprockets and tensioners prevents slack, reduces the risk of timing drift and avoids secondary engine damage from failed timing components. The corrosion-resistant treatment and precision-forged parts are intended to simplify installation and provide a reliable operating surface when fitted correctly.

• Reduces slack and timing wear when all components are replaced together
• Precision forging improves part-to-part engagement and fit accuracy
• Corrosion-resistant coatings help parts resist oil contamination and extend service life

Are there special notes or compatibility checks I should follow before buying?

Yes — some models use two identical right sprockets (12621505) and this kit reflects that configuration. Vehicle production changes mean fitment can vary; use your VIN or the compatibility checker to confirm this kit matches the engine and part references in your vehicle.

• Verify VIN and engine code before ordering
• Compare with OE part numbers like 12621505 and 12635048 for confirmation
• Consult a mechanic if unsure about timing cover or accessory removal requirements

Who is this for: This zuverlass 2.4L Ecotec timing chain kit is aimed at professional mechanics, DIYers with advanced mechanical experience, and repair shops working on mid‑2010s GM 2.4L and certain 2.2L vehicles that require a full timing assembly replacement. It’s best for anyone replacing worn chains and related sprockets/tensioners as part of scheduled maintenance or repair following audible chain noise, timing concerns, or component failure diagnoses.
