General Motors equips the 6.2L L87 V8 engine in seven core vehicles: the Chevrolet Silverado 1500, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra 1500, GMC Yukon, GMC Yukon XL, and Cadillac Escalade (including ESV). Introduced for the 2019 model year, this 420-horsepower, 460 lb-ft torque engine replaces the L86 and features Dynamic Fuel Management instead of従来の Active Fuel Management.
Complete List of GM Vehicles With the L87 Engine
The L87 engine applications span Chevrolet, GMC, and Cadillac truck and SUV platforms built on the T1 platform architecture. All seven vehicles share the same core powertrain specifications while offering distinct trim levels and capability packages.
- Chevrolet Silverado 1500 (2019-present, fourth generation)
- Chevrolet Tahoe (2021-present, fifth generation)
- Chevrolet Suburban (2021-present, twelfth generation)
- GMC Sierra 1500 (2019-present, fourth generation)
- GMC Yukon (2021-present, fifth generation)
- GMC Yukon XL (2021-present, twelfth generation)
- Cadillac Escalade (2021-present, fifth generation) and Escalade ESV
Dealers often omit that the L87 debuted in 2019 exclusively in LTZ and High Country trim levels before expanding to more trims across the lineup. This premium positioning strategy meant buyers purchasing base WT or SLE trims initially received the 5.3L L82 or 3.0L Duramax diesel instead.
L87 Engine Specifications and Performance Data
The 6.2-liter displacement delivers industry-leading towing capacity while maintaining regular 87-octane fuel compatibility, a critical advantage over competitors requiring premium fuel.
| Specification | Value |
|---|---|
| Displacement | 6.2L (376 cu in / 6,162 cc) |
| Horsepower | 420 hp @ 5,600 rpm |
| Torque | 460 lb-ft @ 4,100 rpm |
| Compression Ratio | 11.5:1 |
| Bore x Stroke | 4.065 in x 3.622 in |
| Block Material | 319-T7 Aluminum Alloy |
| Fuel Type | Regular Gasoline (87 Octane) |
| Fuel System | Direct Injection |
| Valvetrain | OHV Pushrod, 16 valves |
| Fuel Management | Dynamic Fuel Management (DFM) |
| Flex Fuel Capable | Yes (E-85) |
| Transmission | 10-Speed Automatic (MQC) |
These exact performance numbers come from GM's own Powered Solutions division testing in the Silverado 1500 Crew Cab configuration. The oil-jet piston cooling system and two-stage oil pump represent continuous heritage technologies from the L86 that improve thermal management under heavy loads.
What Dealers Won't Tell You About the L87
The critical reliability issue separating the L87 from its predecessor involves a staggering 28,000 reported engine failures prior to GM's recall of 600,000 trucks in the United States. Federal regulators have since received 1,157 specific reports of engine bearing failure from the 6.2L V8s, prompting NHTSA to launch a formal investigation in early 2025.
Owners report 12 accidents and 42 fires potentially caused by L87 failures, with GM now facing potential recall of another 300,000 vehicles as problems continue. This represents a global recall affecting approximately 721,000 vehicles when including international markets.
"The primary distinction between the L86 and L87 engines lies in their performance issues." - Yahoo Autos analysis, November 16, 2025
Dealers emphasize the 420 horsepower output but rarely mention the NHTSA investigation opened after receiving more than 100 complaints outside the original recall scope. The bearing failure pattern specifically affects 2019-2024 Silverado 1500 and Sierra 1500 pickups plus 2021-2024 SUVs.
L87 vs L86: Key Differences Explained
While the L86 and L87 share identical horsepower and torque ratings, the L87 introduced Dynamic Fuel Management replacing Active Fuel Management for improved efficiency. The L87 also integrates automatic start/stop capability as a standard feature rather than an optional one.
- Fuel Management System: L87 uses Dynamic Fuel Management (17-cylinder pattern variation) vs. L86's Active Fuel Management (4/6/8-cylinder deactivation)
- Efficiency Gains: L87 delivers modest improvements in fuel economy and CO2 emissions through advanced cylinder deactivation
- Introduction Year: L86 launched 2014, L87 replaced it for 2019 model year
- Reliability Record: L87 has significantly more reported failures (28,000) compared to L86's sporadic complaints
- Recall Status: L87 subject to 600,000-vehicle US recall plus potential additional 300,000-vehicle recall
The Gen V Small Block architecture ensures both engines share the same fundamental design, but the L87's DFM system represents the more sophisticated cylinder deactivation technology. Despite these improvements, the failure rate disparity remains the most consequential difference for buyers.
Towing Capacity and Real-World Performance
The L87 excels at towing with maximum capacities ranging from 7,700 lbs in the Tahoe to 13,300 lbs in the Silverado 1500 when properly equipped. The 460 lb-ft torque at just 4,100 rpm provides strong low-end pulling power essential for heavy trailers.
Acceleration times demonstrate the spirited performance capability, with the Silverado 1500 achieving 0-60 mph in approximately 5.7 seconds despite its 5,000+ lb curb weight. The 10-speed automatic transmission (MQC) seamlessly manages power delivery across the entire RPM range.
Crate Engine Availability and Aftermarket Support
GM officially sells the L87 as a crate engine (part number 1382563) for marine, motorsports, and swap applications, featuring a cast aluminum block and included intake manifold. The block can handle over 1,000 hp with upgraded internals, making it popular among performance builders.
Marine manufacturers including Volvo Penta, Indmar, PCM, and Marine Power frequently used the L87 platform from 2010-2018 before GM's truck application. This proven durability in marine environments suggests strong fundamental engineering despite the bearing issues in truck applications.
Buying Guide: What to Check Before Purchasing
Prospective buyers of L87-equipped vehicles must verify whether their specific VIN is included in the 600,000-vehicle recall campaign before finalizing any purchase. Request complete service records showing oil change intervals, as extended drain intervals correlate strongly with bearing failure incidents.
Inspect for metal shavings in oil during pre-purchase inspections, the primary early warning sign of impending bearing failure. Verify the Dynamic Fuel Management system operates correctly by monitoring cylinder activation patterns during highway cruising.
The L87 remains engineered for robust performance with rectangle intake ports (297cc runner volume) and flat oval exhaust ports (107cc) supporting strong airflow. However, the recall uncertainty means buyers should prioritize vehicles with recall completion documentation and extended warranty coverage.
Final Verdict on L87 Vehicle Ownership
The L87 delivers exceptional power and towing capability across GM's full-size truck and SUV lineup, but buyers must weigh the 28,000 failure reports against the 420-horsepower performance advantage. The regular fuel compatibility and flex-fuel capability provide ongoing cost savings that partially offset potential repair expenses.
For buyers prioritizing maximum capability, the L87 remains the strongest naturally aspirated option in GM's current lineup, but thorough pre-purchase inspection and recall verification are non-negotiable. The impending additional recall of nearly 300,000 vehicles suggests problems may worsen before improving.
Ultimately, the right buyer profile for L87 vehicles includes those who need maximum towing capacity, accept the failure risk, and maintain complete warranty coverage through 2026 and beyond. Dealers' silence on these issues remains the industry's most insanely problematic practice for consumer transparency.
