zuverlass Timing Chain Kit for GM 2.4L & 2.2L (2011–2017) — Complete Kit with Water Pump and Tensioner

If your vehicle is a Chevy, GMC, Buick or Pontiac using GM 2.4L or 2.2L engines, this zuverlass timing chain kit supplies the chain, gears, tensioner, guide rails and OE-matching water pump in one package. The kit fits specific model years and engine codes—intended to simplify a full timing service by providing matched components and well-machined parts to restore correct valve timing and coolant sealing when installed correctly.

Which vehicles and engines does this kit fit?

This kit covers a range of GM cars and crossovers using the 2.4L DOHC and selected 2.2L engines. Compatibility varies by model year and part number, so always confirm against your VIN, engine code, and the OE numbers listed below before ordering.

• 2.4L fitment: Chevy Equinox (2011–2017), Malibu (2013–2014), Impala (2014), Captiva Sport (2012–2015); GMC Terrain (2011–2017); Buick Lacrosse (2011–2016), Regal (2012–2017), Verano (2012–2017).
• 2.2L fitment: Chevy Cobalt (2009–2010), HHR (2009–2011), Pontiac G5 (2009).
• Reference OE numbers in kit details (e.g., 9-4201S, 12621505, 90537632 and water pump numbers) to confirm match.

What parts are included and what are their key specifications?

The zuverlass set bundles all main timing components plus a water pump and associated hardware so you don’t need to source multiple parts. Components are manufactured from hardened and precision-forged materials to meet fit and finish expectations for timing systems.

• Timing chain and dual sprockets (kit listed as 94201S/94201SX variants).
• Tensioner, guide rails, and matching mounting hardware for correct alignment.
• OE-style water pump included with compatible pump part numbers for direct replacement.
• Complete accessory kit to streamline a full timing and cooling front service.

How should I install this kit and what precautions are important?

Installation should follow factory service procedures and torque specifications. Because this kit is intended for DOHC engines, proper timing mark alignment and valve timing calibration are critical; incorrect installation may cause engine damage.

• Verify engine is at specified top-dead-center positions before removing old timing components.
• Replace tensioner and guide rails together with the chain to ensure proper tension and wear characteristics.
• Confirm water pump sealing surfaces and coolant passages are clean; use correct gasket or sealant as instructed.
• After assembly, rotate the engine by hand through two full cycles and re-check timing marks.

Which OE numbers and variants should I check to ensure fit?

Several part numbers are noted for the timing set, sprockets, tensioner and water pump; match these to your vehicle’s listed OE parts. Some kit variants include two identical sprockets—verify whether your engine requires that configuration before purchasing.

• Timing set references: 9-4201S, 12621505, 94201SX and related numbers.
• Water pump references: 12630084, 24439798, 93178602 and others listed in product details.
• Guide rail and tensioner numbers: 13104978 and 12608580 among others—cross-check against dealer parts info.
• Confirm model year, displacement and DOHC designation to avoid mismatches.

Who this is for: Professional mechanics and experienced DIYers performing a full timing and water-pump service on compatible GM 2.4L DOHC or listed 2.2L engines. This all-in-one kit suits owners who want OE-matching components packaged together to reduce parts sourcing time—provided they verify fitment with their vehicle’s VIN, engine code and OE references before installation.
