NS300L™ By Huhn Solutions
THE BENCHMARK IN HEAD BOLT SCREW THREAD REPAIR IN ALUMINUM ENGINE BLOCKS
FIX IT ONCE, FIX IT RIGHT!
The NS300L™ insert system has become the benchmark for repairing aluminum engine blocks.
The NS300L™ Insert System is a very high quality head bolt thread renewal system designed and manufactured in America for aluminum engine blocks to repair damaged or stripped threads, 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 fix 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.
AVAILABLE THREAD SIZES: M10X1.25, M10X1.5, M11X1.25, M11X1.5, M11X2.0, M12x1.25, M12X1.5, M12X1.75 AND 7/16-14.
“Researching the fixes is how I found your company, in case you wanted to know. I'm going to have my master tech do the work and when he heard it was a "coarse thread" repair he cut me off in telling him more and exclaimed "That's the kit you want!!" Guess he had seen the fine thread repair "approved" kits not be as successful. Was nice to see a master tech almost jump up and down!.”
“I looked around for many different products. And I happened to stumble upon NS300L for my 2017 Camaro. The head bolt pulled threads and I had thought about ever possible solution for the fix. I looked at videos. I looked at reviews. I was going to do a time Sert and glad a found this much better product worked like it said. The coarser thread definitely will hold much better in a aluminum block or whatever. I’m so completely satisfied with this thank you very much for your quick response and quick delivery. Will be doing more businesses with you in the future.”
"I just wanted to sincerely thank you for the NS300L. I’m not a mechanic but have no trouble taking things apart and putting them back together again. I have to admit though that I was very nervous about drilling and tapping a block that I couldn’t afford to replace. Your kit was the answer to all my concerns though. Due to your well thought out system, the installation went in with no issues at all. I was quoted $3500.00 to fix this at Toyota IF it worked. IF it didn’t work I’d be replacing my engine. After buying your kit, gaskets, new head bolts, a few tools I didn’t have and some random extras, I spent about $750.00. It was a time consuming job but you saved me a total of about $2750.00. Congratulations! You’re my new best friend! You helped my wife and I stay on course of trying to become debt free and for that I am very grateful. You truly have a great solution to the big problem of stripped head bolts"
"In the 40 some years I have been doing this I have purchased okay tools, good tools, and terrific tools. I have tools boxes and shelves full of obsolete tools I have paid fair prices, good prices and scr*w you prices. Yours falls under the terrific, and a fair price, category"
