YES, YES,
The Pro-Comp Ultra-lite are lightweight guages!!! The are for race cars where weight is an issue. I have about 8 2-5/16" Ultra-lite guages from Drag Pro Civic I use to have. There was def. a big difference in weight comparied to the phantoms, which at white faced, especially with the larger 2-5/16".
There is also a big price difference with them.
