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

Best shocks in the market
I love these shocks! One they are super cheap for a wonderful product. They are super easy to fit in screw in and your ready they are soft springs and stiffer springs they are super durable and will not snap on you. They are amazingly cheap to come with oil filled shocks! They are pretty heavy and stable when installed!

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.

Perfect length shock.
These shocks function well and give you just enough travel to have a good time but not too much to upset the rig. Easy to go together and they look great.

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 shocks for a easy lift
These are perfect for a slight lift on the TRX-4M, without so much you need a longer driveline. I use these on my crawler body, and they really are a hand in hand fit. These come relatively unassembled, you have to put the hollow balls and O-rings on and swap springs if desired. You also have to load them with oil, so be prepared to get or have shock oil. Recommended on these is 20w, I use 30w because I like the stiffer shock. The set comes with all the needed parts, with extras, including another, stiffer set of springs. Neither set is stiff enough for my tastes, but they're all I have until I find more options. My only complaint on these, is the hollow ball ends are either too small or too big with each set. I've bought multiples of these, and the hollow ball ends can either be difficult or easy to get in, depending on the set. Not sure why some ends are bored bigger or if it's just the hollow balls that are different size but either way, they work fine no matter which you get. I would recommend these to others and would purchase again.

Calidad y funcionabilidad
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.
