 NS300L BY HUHN SOLUTIONS VERSES TIMESERT AND HELICOIL HEAD BOLT REPAIR KITS

    The NS300L™ insert system has become the benchmark for repairing aluminum engine blocks.

The NS300L™ Insert System is a head bolt thread repair kit designed and manufactured in the USA for aluminum engine blocks, originally engineered with great success, to outperform all other repairs on the market for the Cadillac Northstar engine. But since it's conception, the NS300L™ Insert System has become the preferred thread repair for many other aluminum engines as well, including the Toyota 2.4L 2AZ-FE. Although other systems may make the claim of being an "approved" kit by some automotive manufacturers, the NS300L™ system has earned the reputation of being a "Confirmed" repair, and  has also earned the title of "Most Reliable"! There's a big difference between "approved" and "confirmed", especially when you figure the expense and frustration of a failed repair! See a list of available kits by manufacturer.
