Although other systems may make the claim of having an "approved" kit by many automotive manufacturers, the
NS300L
™
kit has developed the reputation of being a "confirmed" repair. There is a big difference between "approved" and "confirmed", especially when you figure the expense and frustration of a possible failed repair.
The
NS300L™
Insert System is a head bolt thread repair system originally engineered with great success, to outperform all other repairs on the market for the Cadillac Northstar engine, but s
ince it's conception, the
NS300L™
Insert System has become the preferred head bolt thread repair for most other aluminum engines as well.
Unlike most other repairs, the
NS300L™
thread repair system has been designed to work with every insert we have available which are available for several head bolt thread sizes, eliminating the need to purchase a kit for every different thread size.
This can translate into huge cost savings for shops who do these repairs on a variety of different engines.
This has been achieved by standardizing the outside thread of all of our inserts, which allows the same drill, taps and alignment jig (which is also universal), to be used on many different engines. Replacement inserts are available and can be purchased from us direct.
Available insert sizes:
M12x1.75 (Common in older 4.9L Cadillac and newer GEN IV 6.2L LS9)
M12x1.5 (Common in Honda/Acura V6 engines)
M11x1.5   (Common in Cadillac Northstar, Honda, Nissan, Toyota, Scion Isuzu, Hyundai, KIA and many other import and domestic engines)
M11x1.25 (Common in Subaru and Nissan V6 engines)
M11X2.0 (Common in many GM engines)
M10x1.5   (Common in BMW, Jaguar and Land rover/Range Rover with Jaguar engines)
M10x1.25 (Common in Honda Civic)
7/16-14 (Common in Land Rover)
History of the
insert system
I had privately purchased a pre-owned 1996 Cadillac, and started having problems with it overheating, only to find out that the head bolt holes were stripped out. I then realized that it had been repaired once before with GM-approved solid synchronized inserts, which were also stripped out! After doing some research, I found that the Cadillac Northstar 4.6/4.0L,
Toyota 2.4L 2AZ FE engine and many other aluminum engine blocks
were notorious for the head bolt holes stripping
.
I am a Tool and Die Maker/Machinest by trade and I developed the
NS300L™
Insert System out of necessity and frustration. The
NS300L™
Insert System is a head bolt thread repair system engineered to outperform all other kits on the market for aluminum engine blocks. Unlike thin inserts with synchronized internal and external fine threads such as the GM repair, the
NS300L™
Insert is designed to be a far stronger insert due to its longer length, bigger diameter, and coarser external thread for maximum strength. This prevents the insert from expanding under high torque, and allows the load to be distributed to a much larger area. As a result, the load per thread is much less, significantly reducing the chance of cracking the block. Understand, head bolts/studs do not strip out of steel inserts, they only strip out of the aluminum block itself. The
NS300L™
Insert System has over three times the thread engagement within the aluminum block than the GM-approved first repair insert, over two times that of the GM-approved second repair insert, and almost four times that of the common standard coil type inserts. There is nothing wrong with those other type inserts, they are very well designed inserts for most applications. The challenge with them is they do not always get past the deteriorated aluminum and back into virgin aluminum, due to their smaller diameter and fine external threads (the same fine threads as the head bolt that failed in the first place), and have a tendency to pull out during the head bolt tightening process. Occasionally, those other types of inserts have failed only a few hundred miles after the repair. I have had several technicians contact me with this challenge. They found the
NS300L™
insert gives them a much stronger, more reliable repair, and in return, saves them the expense and frustration of failed repairs. One dealership informed me that they had stopped repairing Northstars with stripped head bolts on engines having over 100K miles, due to the high number of failed repairs with the GM-approved inserts. They felt the
NS300L™
Insert System would be the answer to this challenge, and they have been very pleased with the results. We receive positive feed back on a regular basis from Cadillac, Toyota/Scion, Honda, BMW, Subaru, KIA, HYUNDAI and other technicians, about how impressed they are with the quality, strength and the ease of installation of the
NS300L™
Inserts System.
In fact, the
NS300L™
Insert System is now the thread repair system of choice for general automotive
tech's, automotive machine shops, hot rodders and custom engine builders.
Testimonials
"I wanted to send a letter of thanks for the amazing product you have developed.
My 2003 Camry had the head bolts pull out of the block at 155K miles.
I decided to take a chance and repaired it with your NS300L inserts. Five years later, I have driven another 87,000 miles without a problem. My deepest thanks, and strongest endorsement"

"Obviously, part of a customer’s satisfaction is with the quality of a tool and its ease of use.  It would be hard  to consider a design and execution that could exceed those qualities which I found in your tools…they were truly top notch"

"Norm,
Thank you so much for your ingenious and simple solution to saving threads on aluminum blocks. I received your NS300L kit within 48 hours of ordering it (from all the way cross-country, I might add), and that same evening had all ten threads repaired in five hours. The high-quality tools and hardware, plus the easy-to-follow instructions make this job a breeze. Again I wish to thank you for your great product and prompt, courteous service"

"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 00.00 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 0.00.  It was a time consuming job but you saved me a total of about 50.00.  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"
