What Chevrolet Trucks have LS engines?

These Chevrolet trucks currently come with or came with LS engines: Avalanche, Colorado, Silverado, Tahoe, Trailblazer, and Suburban. The certain models vary throughout the years, and also some, choose the Avalanche, had actually the LS in only specific trim levels. These generally came v the 5.3L, 5.7L, or 6.0L displacements. When the LS’s background is complex, we’ll go into as much detail as feasible for friend to better understand this fascinating engine.

The LS very first came into the industry with the 1997 C5 Corvette, well-known as the Gen III small-block V8. But its commercial surname was LS1. Now, keep in mind the this engine household has a point with names; some don’t even bring the initials LS.

So, prior to we obtain into why this engine is essential and also which trucks have actually them, let’s discuss its specify name origins. Very first of all, LS doesn’t really was standing for something, also if some civilization say that refers to deluxe Sport. In reality, it’s a surname the automotive ar gave to basic Motor’s household of Gen III and also Gen IV small-block V8s.

As because that numbers, lock don’t follow any certain order. Because that example, after ~ the LS1 come the LS6, v the 2001 Z06 Corvette. These 2 engines were so popular, world started introduce to the entire family just as LS. And, as soon as you understand a bit of the genealogy behind them, it renders perfect sense.

This V8 to be so reliable, powerful, and versatile, Chevrolet started providing it in trucks and SUVs with great success. Yet the manufacturer used numerous names, such as Vortec, L33, L76, and others.

By the way, Chevrolet had actually used the LS name for various other engines, as far back as the ’70s. Yes, it’s confusing. That’s why we wrote this article. But, because that the moment, we’ll talk around Gen III and the following models. Next, we’ll uncover out why it was such a effective engine.

What makes the LS engine together a an excellent engine?

To understand why the LS is such a an excellent engine, we must talk about the construction. Chevrolet conceived this powerplant v a “Y” Block. This design increases the strength about essential areas like the cap and also block.

To add to this rigidity, engineers also used extra-long bolts, which organized the head and went deep right into the block. But, surprisingly, the style was such the the engine wasn’t massive.

LS engines are surprisingly light, with many weighing about 450 lbs. Because that comparison’s sake, GM’s Gen III 2.0L inline-4 Ecotec powerplant weights 331 lbs. Then, there’s the size. It’s not unusual to uncover LSs in cars like Miatas.

Truck LS engines came v either an stole or aluminum block. Auto engines, top top the other hand, greatly came with only aluminum blocks. By combine this size, weight, and also versatility, Chevrolet produced a large array the displacements, for example:

Iron-block truck LS engines have 4.8L and also 5.3L displacementsAluminum-block van LS engines have actually a 6.0L displacementAll-aluminum car LS engines have actually 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L displacements

Ironically, this size advantage is due to Chevrolet’s classic approach, using pushrod design. Modern engines v overhead cams yield better performance and also economy. However they’re larger, heavier, and also not together strong.

So far, we’ve watched that the LS is reliable, strong, and small. Yet it doesn’t prevent there because it produces many of power and torque. The heads have wonderful airflow, and the cams can take unusually severe punishment, so it provides for a an excellent engine swap. And, we’ll acquire to this object later.

These traits have earned the LS a cult following, which has generated excellent aftermarket support. Pretty much every vehicle fanatic has fiddled v an LS engine. So, parts are simple to find.

Plus, Chevrolet has actually made numerous thousands of this engines, so some are relatively cheap, and also spares are affordable. No wonder civilization love them.

The Gen V engine still supplies the timeless construction the made the LS famous. But, there’s tiny interchangeability with the previous 2 models.

Chevrolet readjusted the intake and exhaust valve positioning. Other improvements incorporate a longer camshaft, straight injection, change valve timing. These additionally distance the from the larger engines.

Most use an all-aluminum block and also heads, with some utilizing an steel block. However Chevrolet has actually yet to adjust the two-valve pushrod design.
