L84 5.3L Replacement Engines & Rebuilds
Explore L84 performance optionsFind the right 5.3L engine for your Chevrolet or GMC. Compare actual product listings, review the build and warranty, then request help or place your order.
Start with the original engine
The listings below cover L84 applications including 2019+ Silverado/Sierra and 2021+ Tahoe/Suburban/Yukon. Confirm the original engine code before selecting a replacement.
Model years describe the application family, not automatic interchange. VIN/RPO, drivetrain, controls, fuel system, accessories and emissions configuration must match. L82, L83 and L84 are not interchangeable solely because each is a 5.3L.
Non-AFM or Non-DFM configurations require the hardware and calibration specified for the ordered build. Tell us about existing modifications and your intended use.

Rebuild or replacement
For an application-matched repair, compare customer-core rebuilding with the replacement long blocks offered for your engine. Inspection and the written build scope determine what is renewed or reconditioned.
Upgraded components
Where listed, enhanced, premium and new-component builds offer different component packages. Compare the actual parts list, not the tier name alone. Performance use needs its own configuration review.
Precision work with a defined scope
ETI Performance LLC provides full-service machine work using Van Norman and Sunnen equipment. Engine rebuilding includes application review, disassembly and cleaning, inspection and measurement, the agreed machining and component work, and assembly checks. The operations required depend on condition and the selected build.
Katech cylinder-head porting on Rottler CNC equipment and Spintron testing are available for selected work. Neither is automatically included in every replacement engine.

Help me choose my L84 performance engineWarranty, core and delivery
Warranty is product-specific. A recycled engine, Big 3 rebuilt engine and performance component do not automatically share coverage. Review the selected product and controlling written terms for duration, mileage, parts/labor scope, installation requirements and maintenance instructions.
Confirm core charges, return requirements, freight and availability before ordering. Texas installation and nationwide vehicle transportation can be quoted separately.

Start with your engine code
Shopping for a 5.3L or 6.2L replacement? These LT-family pages compare actual product options. Model years change at different times across pickups and SUVs. A Denali badge, shared displacement or similar photograph does not establish interchange. Confirm the VIN, engine code and original configuration first.

These are family-selection links, not a fitment list for every vehicle on this page. Older LS-family engines, HD trucks, diesels and specialty configurations need their own identification.
Need a transmission instead?
Send the VIN, transmission code or identification-label photo, engine details and 2WD/4WD configuration. Confirm the supplied converter, controls, programming, cooling-system work and installation scope in the quote. Engine displacement alone is not enough to select a transmission.
Compare the complete repair cost
Compare the exact assembly price with installation, transferred accessories, required repairs and delivery. Core deposits are individually quoted and collected separately. Multiple engines, transmissions or mixed freight items require a shipping quote.
