ATRACYPART 6.6L Duramax Oil Filter 5-Micron — 2-Pack Spin-On OE Replacement 114000555

High‑performance replacement oil filter cartridge designed for 6.6L Duramax engines (LB7, LLY, LBZ, LMM, LML) — 5‑micron media in a 2‑pack that replaces OE 114000555 (upgrade of PF2232).

This ATRACYPART 2‑pack of spin‑on oil filters is engineered specifically for Chevrolet and GMC heavy‑duty trucks with the 6.6L Duramax diesel from 2001 through 2019. Each filter element is built to remove fine contaminants while preserving oil flow, helping maintain consistent lubrication and protecting critical engine and transmission components. The steel canister and paper media provide an easy, familiar installation that matches OE dimensions and service intervals.

How does this filter protect my Duramax engine?

The 5‑micron filtration media captures small particles that can accelerate wear on bearings, camshafts, and turbo components while allowing sufficient oil flow for cooling and lubrication. The multilayer paper element and reinforced canister resist collapse under pressure and during long service intervals.

• 5‑micron nominal media for effective particle removal
• Over 2.5× more filter surface area for longer service life
• Steel canister resists deformation and maintains pressure integrity
• Full‑flow spin‑on design for consistent oil circulation

Will this part fit my Silverado or Sierra model?

These filters are made to replace OE 114000555 (upgrade of PF2232) and fit most 6.6L Duramax applications listed by model year and engine code. Always verify compatibility with your existing part number or vehicle fitment list before purchasing to ensure a correct match.

• Fits Chevy Silverado 2500/3500 and Express 2500–4500 models within the specified years
• Fits GMC Sierra 2500/3500 and Savana 2500–4500 models within the specified years
• Compatible with LB7, LLY, LBZ, LMM, and LML engines
• Replaces OE numbers including 114000555 and PF2232 upgrade

How easy is installation and what tools do I need?

Installation follows the familiar spin‑on filter routine and requires only basic hand tools: an oil filter wrench, drain pan, and a torque or hand tight finish as recommended. The filter’s OE‑style threading and gasket size ensure a quick swap during routine oil changes.

• Spin‑on design for handable installation and removal
• Standard oil filter wrench fits the canister outer surface
• Minimal tools required—ideal for home DIY or quick shop service
• Replace at manufacturer interval or during each oil change

What performance and durability benefits should I expect?

The combination of increased filter surface area and durable construction reduces pressure drop and extends effective service life, helping maintain oil cleanliness under towing, hauling, and highway driving conditions. Robust materials also help preserve gearbox and engine longevity by minimizing abrasive wear.

• Improved contaminant capacity lowers frequency of premature restriction
• Durable construction stands up to heavy‑duty use and heat
• Helps maintain consistent oil pressure and lubrication performance
