Introduction To Welded Diffs
Welding a differential, or diff, is a technique used by car enthusiasts. It involves permanently locking the gears inside the differential. This process can affect the vehicle’s performance in various ways. In this section, we will explore what a welded diff is and its purpose and use cases.
What Is A Welded Diff?
A welded diff is a modified differential. The internal gears are welded together. This causes both wheels on an axle to rotate at the same speed. Normally, differentials allow wheels to rotate at different speeds. This is helpful during turns. But with a welded diff, this differential action is eliminated.
Purpose And Use Cases
Welded diffs are common in motorsports. They provide better traction in certain conditions. For example, in drifting, both wheels need to spin together. This helps maintain control during slides. Off-road vehicles also benefit from welded diffs. They need equal power to both wheels in tough terrains.
Street cars rarely use welded diffs. They can make daily driving difficult. Turning becomes harder because both wheels turn at the same speed. This can lead to tire wear and other issues. So, welded diffs are mostly for specific performance needs.
