Quality built shocks worth the money
Bought set of blue shocks before. These shocks are much better quality compared to the other name brand. Smooth travel. They don’t stick. Installed in my trx4 Chevy 4x4 1/18 looks fantastic. Work very well. Definitely recommend

Perfect
Nice, might need oil. Most shocks dont come with oil inside. Its a hazard concern if it leaks. So dont leave a bad review because they didn't have oil. These shock work awesome and look sweet

Great for the TRX4M - High Trail, once you add oil!
These are great shocks, but you have to add oil to them. We added 22.5 wt and they are performing well.

Good shocks, but wrong size hardware was included
Good shocks, but I received the wrong size brass fittings that you need to install before mounting the shocks. Thankfully I have another rig running these shocks that I was able to borrow the right size parts to put on my bug18 build, but now I need to replace those before I get that one up and running again.

First ever issue with Injora product....
UPDATE: I have to say... I had to go up to 5 stars on this product... after my review customer service contacted me and wanted to make it right immediately... showed them the problem and they sent me a new shock right away... again proving the company is amazing and has great quality products and stellar customer service... thank you again Injora... I for the most part love Injora and all the things I have purchased over the time for both of my TRX4M's except this item.. Let me first say, I would have loved this item as everything else, except I took the cap off to put shock oil, and only to find out the cap is stripped from the body. It literally will not thread back on the body and stay. Worst part is the cap isn't stripped but instead it is the shock body itself the threads are stripped so not even where I could just use a different cap on the shock... sucks because I was really excited about using these and love them, just not usable without getting a correct fixed 4th shock... Again just was one of those bad luck of the draws I guess and got a bad set this time...

Great for my MN99S
The metal shock extension they are perfect for the MN Model MN99S and the front shocks of the MN86. I have tried many cheap shocks for the MN99s and was disappointed because they either leak or are a terrible fit. The Injorna shocks fit perfectly. They come with two different spring rates, and I found the stiffer springs worked better for my driving style. The factory does not mount the stiffer springs, but they are included in a bag. The mounting method is also very nice; just put one o-ring on, insert the brass stud in the hole, and then put the second o-ring on. Very easy. You must fill them with shock oil; I used 20-weight oil. Most shocks from the factory without oil prevent them from making a mess in shipping, so I understand.

Perfetti per quello che volevo fare.

Funcionan perfectamente en mi TRX4M Defender, dándole un poco mas de altura, permiten pasar mejor los obstáculos al tener mas recorrido, y además le añade un poco mas de peso que las originales.
