Well made kit, must have for LS engine work
Well made kit. Must have for assembling your LS engine. Each alignment jig also doubles as a seal driver which is very helpful. Instructions are easy to follow, just wish the print was bigger because I'm old and blind :)

Awesome
Best I've ever had a front cover aligned on my engines and I'm very good at doing it without a tool. They work great to install seals as well. Awesome stuff and for $25 buying to use once is totally worth it for the average customer.

Real Nice but
Everything about this is very nice BUT the front cover alignment tool could be longer so it could also be a rear alignment tool. Kinda dumb that itโs not

Well made!
Used it to install the rear seal and worked very well. Don't pop out the plastic insert. It's used to align the seal. Put it (the seal) over the end of the crank and put your fingers at 10, 2, 4 and 8 o'clock and push the seal in. Use the tool to tap the seal in until it bottoms out. (service manual indicates the seal should be tapped in until it bottoms out).
