FEATURED ENGINE: 5.3 AND 6.0 L GM LS ENGINES GEN III AND IV LS

The 'LS' line of engines from GM has been hugely popular since they were first unveiled, taking over for the famous small block line of engines. The Gen III and Gen IV versions of the LS engines were offered in many pick up, van, SUV and car applications and ranged from 4.8L to 7.0L sizes. The later model versions of this engine, like this 5.3L Chevy engine, feature Active Fuel Management (AFM) to increase fuel economy and decrease emissions.

Tri Star remanufactured 5.3 and 6.0 L GM LS engines are completely remanufactured including machining the block, crank, connecting rods and cylinder heads, and assembled with new or remanufactured parts. Rebuilt GM 5.3L and 6.0L LS engines will only correct the issue with the "core" engine used as raw material, but will typically not include any other machining or remanufacturing on the rest of the engine or have any updates performed. Used engines incorporate no updates and are extremely susceptible to failure due to mileage already being on the engine with questionable maintenance records. Used and rebuilt 5.3L and 6.0L LS engines are inferior, do not correct any of the original equipment design flaws and typically have very limited or pro-rated warranties. When shopping be sure to ask if you're getting a used, rebuilt 5.3L and 6.0L LS engine or a 100% remanufactured engine.

 The 5.3L and 6.0L LS engines are notorious for having cracked cylinder heads, excessive oil consumption, and lifter noise (on Gen IV engines).  Tri Star remanufactured 5.3L and 6.0L LS engines address these most common failure points in the remanufacturing process to provide the most durable and dependable engines.

OTHER UPGRADES/BENEFITS:

• An AFM oil manifold is installed - Some competitors do not include this expensive part or use an inferior brand 
• Graphite coated hypereutectic pistons resist scuffing and damage to heat much better than factory aluminum pistons
• Moly piston rings and steel compression rings reduce friction and cylinder wall wear to extend the life of the engine
• Multi-Layer Steel (MLS) head gaskets are used which resist heat and avoid head gasket failures
• Fel-Pro® rear main seals protect against heat and leaks
• Connecting rods are honed (both the little and big ends) to ensure uniformity, and bent rods are scrapped (some competitors will bend rods back into place)
• Chrome plated valve stems resist scuffing and heat for greater durability
  
• Soda blasting aluminum components provides a visually 'like new' raw material without the risk of contaminating the engine (some competitors blast with  other abrasive materials which can become stuck in the engine and cause the new engine to fail)
  
• Every engine is 100% simulation tested very thoroughly by skilled technicians. Engines are checked for good compression, oil pressure, and black light checked for any leaks before packaging
• Engines are provided with a written warranty which clearly outlines coverages. Unlike some competitors, Tri Star warranties are not 'pro-rated' which decrease your coverage over time
• Engines are shipped in plastic totes with simple core return instructions provided to make returning cores extremely simple
• Excellent product support technicians aren't just order takers, they are knowledgeable customer service experts
  
• You're buying your remanufactured 5.3L direct from the manufacturer so you know you aren't dealing with a middle man for increased costs and headaches for warranty, core returns and technical assistance
