How to Add Power Steering to Your Classic Car

Adding power steering is a very popular modification for older vehicles, most notably old trucks or muscle cars. These vehicles usually have large V8 engines that put a lot of weight over the front wheels, and the trucks often have large, heavy off-road tires that further exacerbate the problem. Power steering reduces the amount of…

What is Magnetic Ride Control?

Magnetic Ride Control, trademarked and frequently referred to as MagneRide, is an electronic suspension system developed by Delphi. It was first available on the 2002 Cadillac Seville STS, and soon made its way to other General Motors vehicles, making its mainstream debut on 2015 and newer Chevy and GMC full-size pickups and SUVs.

Fewer parts means it takes up less space, so it’s easier for the manufacturers to package everything under the hood.…

How to Replace Your Autoride Shocks the Right Way

The Autoride suspension available on most full-size 2000-2014 General Motors Full-Size SUVs (RPO Code Z55) is a complex, and often misunderstood system.

How to Identify Your Duramax Diesel Engine Code

For the 2001 model year, General Motors finally replaced the Detroit Diesel 6.2L and 6.5L turbodiesel V8’s they had been using for 20 years, with a new 6.6L V8 developed in-house with Isuzu’s heavy truck division.
