LS engine builders and mechanics, this alignment tool set is absolutely essential for doing the job right!
If you're working on any GM LS engine - 4.8, 5.3, 5.7, 6.0, LS1, LS2, LS3, LS6, L99, you name it - these tools ensure perfect alignment of the front cover, rear cover, and oil pan.

The aluminum construction is precise and won't rust or corrode in your toolbox.

Here's why this matters: on LS engines, the oil pan is actually a structural component that adds rigidity to the block, and the front and rear covers need to be perfectly centered for the seals to work properly.

Without proper alignment, you'll end up with oil leaks and premature seal failure.
This tool set mimics the crankshaft balancer and oil pan mounting surfaces to get everything lined up perfectly before you torque everything down.
Saves you from having to redo jobs because of leaks.
The tolerances are tight and the quality is professional-grade.

Whether you're building performance engines or just doing maintenance, having these alignment tools means you're doing the job right the first time.

Seriously, don't gamble with LS engine seals - this affordable tool set pays for itself by preventing costly comebacks and leaks.
