59MM Oil Longer Threaded Shocks for TRX4M K10 High Trail Upgrade

Perfect addition to my TRX4m defender. Raised the height significantly and more stability.

Very good shocks

Arrived quickly enough and the build quality is great! I did however receive incorrect hardware with my set, the shocks each require a 2-flange pivot ball and a 1 flange pivot ball, so I should have 4 of each totaling 8. I received 10 (fine, some extras) but only one was a 2-flange meaning I couldn't use the shocks yet. Injora customer service was very responsive and shipped me a new set of pivot balls but it took 2 weeks to get here from China. My other gripe is that these come with varying hardness of springs but there's no way to tell them apart because they're all the same colour and have no markings. You can SORT of see a thickness difference and MAYBE feel it, but if I go by that then I have 7 hard and 3 soft springs... SO I installed whatever springs I had closest on the truck and since I"m not in competition maybe it doesn't matter, but this could matter to others.

INJORA has been one of my go-to brands for RC crawler upgrades, and these 59mm threaded oil-filled shocks are another great addition to my TRX-4M Bronco build. The shocks have a solid feel and a quality finish, and I really like the red aluminum design. The threaded bodies are a great feature because they allow for spring preload adjustments, making it easier to fine-tune the suspension to suit your setup. They come with two different spring rates, 0.45mm and 0.5mm, giving you options when setting up your suspension. I also appreciate that these are oil-filled dampers rather than basic friction shocks, which is exactly what I wanted for my crawler build. The longer 59mm size is worth considering if you’re building a modified TRX-4M with an upgraded chassis, links, or other suspension components. Just make sure you check your setup and mounting points before ordering, as longer shocks can affect ride height, suspension travel, and driveline angles. Overall, I’m very happy with these shocks. They look great, have the adjustability I wanted, and fit the direction I’m taking with my custom build. INJORA continues to offer some excellent upgrade options for RC crawler enthusiasts. Five stars from me! I’d happily recommend these to anyone looking to upgrade their TRX-4M suspension, provided they confirm the length and mounting compatibility for their particular setup.

Perfetti per quello che volevo fare.

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.

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.

Gute Dämpfer, die jetzt in meinem TRX4M verbaut sind
