Details:

Due to your well thought out system, the installation went in with no issues at all. The NS300L insert has become the benchmark for repairing aluminum engine blocks. The quality and workmanship was excellent. Occasionally, those other types of inserts have failed only a few hundred miles after the repair.

There is nothing wrong with those other type inserts, they are very well designed inserts for most applications. The high-quality tools and hardware, plus the easy-to-follow instructions make this job a breeze. I called and he was more than happy to explain everything even threw out some extra advice. You helped my wife and I stay on course of trying to become debt free for that am very grateful.

Hun solutions. Congratulations. OK, so I don't right testimonials for products very often at all. There is a big difference between approved and confirmed, especially when you figure the expense frustration of possible failed repair.

I m not a mechanic but have no trouble taking things apart and putting them back together again. This prevents the insert from expanding under high torque, and allows load to be distributed a much larger area. As a result, the load per thread is much less, significantly reducing chance of cracking block.

Mr Hun, your kit saved the day. I have had several technicians contact me with this challenge. The last thing that I wanted to do was install another fine thread insert, because if they failed, would have had no other option, than replace the engine block. I then realized that it had been repaired once before with gm-approved solid synchronized inserts, which were also stripped out.

Although other systems may make the claim of having an approved kit by many automotive manufacturers, NS300L has developed reputation being a confirmed repair. This has been achieved by standardizing the outside thread of all our inserts, which allows same drill, taps and alignment jig which is also universal, to be used on many different engines. If it didn work ibex replacing my engine. I have to admit though that was very nervous about drilling and tapping a block couldn afford replace.

You re my new best friend. Your kit was the answer to all my concerns though. 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 Cadillac north star engine, but since its conception, has become preferred most aluminum engines as well. 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.

You truly have a great solution to the big problem of stripped head bolts. I have tools boxes and shelves full of obsolete paid fair prices, good prices scar w you. Also the inserts in this kit are 1 long rather than as depicted picture. The challenge with them is they do not always get past the deteriorated aluminum and back into virgin aluminum, due to their smaller diameter fine external threads the same as head bolt that failed in first place, have a tendency pull out during tightening process.

Understand, head bolts/studs do not strip out of steel inserts, they only the aluminum block itself. The challenge with the second repair is, it also had same fine threads as failed gm-approved first inserts.
