Armker LS High-Volume Oil Pump & Timing Chain Kit for Chevy/GMC 4.8L–6.0L — M295HV, +18% Oil Flow, Gasket Set

Armker M295HV LS High-Volume Oil Pump Timing Chain Kit is a complete replacement kit that upgrades oil flow by 18% and includes a precision timing chain, sprockets, gaskets, and a matched high-volume oil pump for Gen III/IV 4.8L–6.0L Chevy/GMC/Cadillac V8 engines.

This kit is engineered to restore correct valve timing and improve lubrication performance on LS-series engines—LS1, LS2, LS3, L96, LM7, LR4, LQ4 and compatible blocks. Supplied components are matched for fit and function so you receive the timing chain, cam and crank sprockets, timing cover gasket set, and a higher-capacity oil pump built to withstand heavier loads and high-mileage applications.

How does this kit improve engine oiling compared to a standard OE pump?

The included M295HV oil pump offers roughly 18% greater oil displacement than many stock units, which raises idle and operating oil pressure under load. Higher flow helps maintain film strength at bearings and valve train components during racing, towing, or engines with wear.

• 18% increase in oil flow vs typical factory pump
• Better idle oil pressure and improved pressure under higher RPMs
• Precision-machined rotor set for consistent volumetric efficiency

Will the timing chain and sprockets fit my LS 4.8L–6.0L engine?

Yes—this M295HV kit is made specifically for many Gen III and Gen IV LS-series V8s spanning 4.8L, 5.3L, 5.7L, and 6.0L displacements. The components are manufactured to match OE dimensions so they align with factory cam and crank geometry when installed correctly.

• Compatible with LS1, LS2, LS3, L96, LM7, LR4, LQ4 engine families
• Designed for Chevy, GMC, Cadillac models from 1997–2013
• Includes timing cover gaskets for leak-free installation

What materials and manufacturing quality can I expect from the Armker kit?

Armker components are built from high-strength metals and wear-resistant materials to endure long service intervals and heavier-duty use. The timing chain and sprockets are heat-treated and machined for durability, while the oil pump uses precision-cut rotors and hardened housings for consistent pressure delivery.

• Heat-treated chain and sprockets for reduced stretch
• Durable gasket set to resist oil leaks and gasket creep
• High-precision pump internals for long-term reliability

How does installation affect engine performance and longevity?

Replacing worn timing components and upgrading to a higher-volume oil pump can restore accurate timing and improve lubrication, which together reduce risk of premature wear. Proper installation and torqueing to factory specs are essential to realize benefits and avoid timing or oil-pressure issues.

• Restores correct cam/crank timing for smoother operation
• Improved oil delivery protects bearings and valvetrain parts
• Recommended during engine rebuilds or when addressing oil-pressure or timing-chain wear

Who this is for: The Armker M295HV LS High-Volume Oil Pump Timing Chain Kit is aimed at mechanics, engine builders, and DIY enthusiasts rebuilding or refreshing Gen III/IV LS-family engines in Chevy, GMC, and Cadillac trucks and SUVs. It’s particularly useful for high-mileage engines, vehicles used for towing or heavy-duty duties, and anyone wanting improved idle and operating oil pressure without changing pump drive geometry. If you need matched timing components plus a durable, higher-flow pump to support extended service life and better lubrication, this kit provides a practical, direct replacement solution.
