L87 6.2L Replacement Engines and Performance Builds
Shop L87 6.2L replacement, rebuilt, remanufactured and performance engines for Silverado, Sierra, Yukon and Escalade applications. Nationwide freight and Texas installation available.
About the L87 6.2L Engine
The L87 is a 6.2L Gen V LT engine used in premium GM trucks and SUVs including Silverado, Sierra, Yukon, and Escalade. It features DFM (Dynamic Fuel Management) for improved efficiency. Exact vehicle application and proposed configuration are confirmed by VIN before ordering.
Big 3 offers recycled, customer-core rebuilt, standard rebuilt, enhanced, premium, new long-block, and performance options. Availability and exact configuration must be confirmed. All long blocks exclude tinware.
Availability and lead time vary by source and configuration and are confirmed on the written quote. Core charge and availability depend on the selected option and must be confirmed at order. VIN verification is required before sale.
Precision Block & Bore Preparation
Big 3's engine program is supported by ETI Performance LLC, a full-service machine shop equipped with Van Norman and Sunnen machinery. Specialized cylinder-head porting is performed by Katech using Rottler CNC equipment. We also use Spintron testing to evaluate valvetrain operation on selected Big 3 builds and engines received from other builders. The machining, porting and testing performed depends on the engine and ordered configuration.

Advanced Cylinder Head Port Work
Port and chamber work is selected for the ordered combination; scope depends on the quoted cylinder-head package.
L87 Fitment & Vehicle Applications
The L87 6.2L Gen V LT engine is factory-installed in premium GM trucks and SUVs. Exact fitment depends on model year, transmission, and vehicle configuration. VIN verification is required before ordering to confirm your engine family and ensure the proposed configuration matches your application.
Primary L87 Applications
- Chevrolet Silverado 1500 and GMC Sierra 1500: 2019+ new-body-style (factory-equipped 6.2L L87). Note 2019 transition/carryover; VIN/RPO/calibration verification mandatory.
- Chevrolet Tahoe/Suburban, GMC Yukon/XL, Cadillac Escalade/ESV: 2021+ redesign (factory-equipped L87).
- 2014–2018 6.2L Applications: Explicitly use the L86 engine. Please visit the L86 Engine page for those model years.
- Later Model-Year Coverage: Subject to VIN, emissions, calibration, transmission, DFM hardware, accessory/tinware, and catalog confirmation.
Fitment Confirmation
Before ordering, provide your vehicle's VIN so we can verify:
VIN; RPO code; exact engine code and generation; control strategy and calibration; transmission; oil pan, covers, tinware and accessory configuration; direct-injection hardware; DFM configuration; emissions equipment.
Year and model alone are not enough, and another LT-family engine is not automatically interchangeable with an L87.
Stock Replacement Tier Comparison
Choose the right stock replacement tier based on your budget, warranty needs, and performance expectations. All tiers include VIN verification. Availability and lead time vary by source and configuration. Contact us for current pricing and availability.

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.
