The timing cover and rear cover on GM LS series engines don't have any dowel pins to ensure correct alignment to the centerline of the crankshaft & this often leads to annoying leaks at the front damper seal and rear main seal. These special alignment tools center the front or rear cover when it is installed, and allow an easy way to install the seal (by lightly tapping on the tool w/ rubber mallet). Choose from (3) styles of these alignment tools. Plastic construction w/O-rings. Made in the USA.
- Front Cover Alignment Tool
- Centers Cover On the Crankshaft To Avoid Seal Leaks
- Plastic Construction w/O-Rings
- Made In The USA
Holley Performance Emission Code 5: This part is legal for sale or use on Emissions Controlled Vehicles; Uncontrolled (Non-Emissions Controlled) Vehicles; and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations
Note: Apply motor oil to O-Rings on tool - helps to prevent damage to O-rings.
LSTC1 tool is slightly more accurate than the LSTC2 tool since the rubber seal in the cover is a little more flexible.
