Universal Coilover Adjustment Spanner Wrench Set, 4 Pc. Tool Kit for Suspension System and Shock Adjustments, Small, Medium, and Large Spanners

Worked great

These were the perfect size for my Japanese market Yashio Factory coilovers on my s14! They were also incredibly strong! I had a couple stuck ones that the previous owner actually used loctite on!! These took a beating from a sledgehammer and broke them loose! I will say that the rubber handle didn't like that very much though. I can't say what other coilovers they will fit but the Yashio Factory ones are custom spec'd HKS coilovers. So they should work on those as well.

I didn't have spanner wrenches of my own and wanted to adjust my coilovers. After looking I found these guys. They are really good quality I was surprised!! Come with a nice carrying bag, and also they have a spot where a breaker bar can be attached, which trust me, you will be so happy to have and will make your life so much easier.

This tool bend but they do the job.

I was skeptical about these because of the price but these were well worth it and it was my first time adjusting the height on my coilovers and the gripped the spanners perfectly.

For my rev89 coilovers on my Civic del sol, these wrenches managed to fit. It is mentioned in the manual for the coilovers to not use wrenches / spanners like these two loosen or make tight the adjustments. However, the tooth of these wrench fit well in the gap where you are to place them, and the wrench is sturdy. As well, the red grip handle and the case are made of good material, I wiped them and put them away and they work well.For the price, this is an excellent buy and also arrived on time. The price I purchased for was less than $30USD- well worth it.

The set isn't bad, just not amazing. The metal is very malubale if your putting enough force behind it to tighten or loosen coilover. Not to mention the grips slip off easily when used. My set I received also came with 3 different sizes, and not 4. If someone is saying 4 different sizes they either sent me two of the same large wrenches, or it's really only 3 and the two large are the exact same. I was also not able to use these on my 2.0 Halo Lift Boss Coilover, and the largest wrench did not fit at all. Overall I gave it a 3 star because the price isn't horrible, but the set is definitely lacking in strength, correct sizes/ quantity of different tools ( is it 3 or 4 different), and the quality (a grip that comes off loose the 1st time using it isn't the best.)
