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 since 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 with an overheating problem, 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 also stripped out! After doing some research, I found that a larger diameter GM-approved "second repair" insert was available. The challenge with the second repair is, it also had the same fine threads as the failed synchronized "first repair" inserts. The last thing that I wanted to do was to install another fine thread insert, because if it failed again, I would have had no other option, other than to replace the engine block. Testimonials "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). The high-quality tools and hardware, plus the easy-to-follow instructions make this job a breeze.

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 short thin synchronized inserts and coil type insert with synchronized internal and external fine threads, the NS300L™ insert system is designed to be a much stronger repair due to its extra length, larger external diameter and coarse external thread which greatly reduces the chance of cracking the block since it's size is designed to distributes the load to a much larger area. There is nothing wrong with those other type of repairs, 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 that failed in the first place). In the case of the SUBARU blocks which uses a finer head bolt thread normally found in most aluminum engine blocks, it's even more critical to use an insert which grips the block as much a possible. Occasionally, those other types of repairs have failed only a few hundred miles after the repair. We have had several technicians contact us 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. We receive positive feed back on a regular basis from Cadillac, Toyota/Scion, Honda, BMW, Subaru 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.
