When did Dodge switch from LA to Magnum?
The switch began in the 1992 model year, when Magnum-branded V8s replaced much of the older LA lineup; Dodge continued the shift through the mid-1990s.
What the terms mean
LA (Light A) is the family of small-block V8 engines Chrysler introduced in the 1960s that powered many Dodge vehicles, including the 273, 318, 340, and 360. The Magnum designation began in 1992 with updated versions of the 5.2 L (318) and 5.9 L (360) V8s, marking the transition to a new generation of Chrysler/Dodge engines. The Magnum engines featured redesigned cylinder heads, improved intake manifolds, and other efficiency improvements, and gradually replaced the LA engines in new vehicle applications.
Timeline of the switch
Key milestones chart the pace and scope of the transition from LA to Magnum across Dodge's lineup.
- 1992 model year: Introduction of Magnum 5.2 L (318) and 5.9 L (360) V8 engines in Dodge Ram pickups and other models, signaling the formal shift away from LA labeling on new engines.
- Early to mid-1990s: Magnum engines are progressively adopted in more Dodge and Chrysler vehicles; some LA-based engines are retired from new production.
- Mid to late 1990s: The Magnum name becomes standard for newly developed V8s; production using LA V8s declines significantly and eventually ceases for new models.
- Late 1990s to early 2000s: The Magnum-era V8s power a broad range of Dodge trucks, vans, and performance cars, reinforcing the transition from the LA family.
Note: While the official branding shifted to Magnum in 1992, some older LA-based engines continued to appear in inventory or certain applications for a limited time, as production lines rotated and parts remained available.
Context and impact
What changed for owners and mechanics
Mechanically, the Magnum engines introduced improvements in heads, induction, and reliability, while the support ecosystem—parts catalogs, service manuals, and dealer training—also migrated to Magnum nomenclature and part identification over the 1990s. For collectors, the Magnum era marks a distinct generation of Chrysler/Dodge V8s that evolved from the long-running LA design.
Why the switch mattered in the market
The transition reflected Chrysler's broader push to modernize its modular V8 lineup, improve power and efficiency, and simplify branding across trucks, vans, and performance cars. It also helped set the stage for later generations of Mopar engines, including the Hemi lineage, by establishing a unified naming and development path.
Summary
The Dodge-LA to Magnum switch began in 1992, with the introduction of Magnum 5.2 L and 5.9 L V8s, and was largely complete by the mid- to late-1990s as Magnum became the standard engine designation. The change represents a pivotal step in Chrysler/Dodge's engine evolution, bridging classic LA blocks with a modern family that would carry through the next decades.
What year did Dodge start making the Magnum?
The most recent version of the Dodge Magnum, known as the "modern" or "LX" platform version, came out in 2004 as a 2005 model year vehicle and was produced until the 2008 model year. The original Dodge Magnum was a different model, a large coupe, that was produced in 1978.

When did Dodge switch from Magnum to HEMI?
The 5.7 L HEMI was released for model year 2003 on the Dodge Ram pickup trucks to supplant the Magnum 5.9 engine.
Why did Dodge get rid of the Magnum?
They had a contract with Daimler that helped Dodge stay afloat. One of the conditions was Daimler would design cars for Dodge. The Caliber and the Magnums were a part of those designs. Once the terms were up, the models went away.
What years did Dodge use the 5.9 Magnum?
The 5.9 L came factory-installed in 1998–2001 Dodge Dakota R/T pickups and 2000–2003 Dodge Durango R/T SUVs. It was also installed in the Jeep Grand Cherokee Limited 5.9, only available in 1998. The 5.9 L Magnum was available until the 2003 model year, when it was replaced with the 5.7 L Hemi V8 engine.
