The LS Goes Off-Road
 

General Motors LS engines have developed a reputation as some of the most versatile power plants in history. These engines that make up the Gen III and Gen IV Small-Block family are known as powerful and reliable choices from the show to the track. 
 
They perform on the off-road course, too.

Fittingly, the GM LS platform’s off-road prowess was on display during this year’s Off-Road Experience at Holley LS Fest East in Bowling Green, Kentucky. In the shadow of Beech Bend Park’s famed “Kentucky Rumbler” roller coaster, a variety of purpose-built off-road vehicles let dirt fly for three days in early September. 
 
Among the vehicles on hand were multiple high-powered buggies, trophy trucks, a stock-appearing square-body Chevrolet pickup truck and even some hoopties. 

While many of the engines at LS Fest were swaps or specially built mills, Chevrolet Performance is also involved in the off-road world, primarily through its 525 RLB crate engine.*  
 
The LS-based 525 RLB is a long-block assembly derived from the Bowtie’s CT525 crate option* and is available for universal sanctioning bodies. It has become a top choice of off-road racers competing in spec truck classes in the western United States. Now, it is poised to make its way to other off-road programs – including LS Fest.
