Night & day from stock! Best cheap/quick upgrade for the TRX4M’s!
Honestly great product, probably the best functional upgrade i’ve done on my mini Defender. Great fit, very easy to install, & the best bang for buck mod to keep this car still scale looking enough while adding a ton of travel/flex!! On level ground it sits about stock ride height maybe a tiny bit lower, but the flex is easily doubled or more from stock! Very highly recommend.

must have for your crawler
they are awesome. although for stock shocks it seems like the torque twist is very extreme so be prepared to address it.

Tons of flex!
These add a ton of flex and fit right on my stock chassis. Had slight rubbing issues but that's all sorted out. easy to install and add a lot of performance to a rock crawler. Look super cool when flexed out and i dont really notice the weight. Good price for more flex

Great product but….
So overall this is another good quality product. Installation, fit and finish is of good quality and all goes together very good. However from my personal experience (not very much) I’m having a hard time with these. When it comes to articulation, these added so much flex to my stock TRX4m. Crawling was so much better on not much of an incline. When crawling or climbing an incline, this made my machine worse than stock. It will twist and lift the front end so much that it will flip. I’ve messed with it over and over again with different combinations and no luck. I did leave the top half installed to relocate the upper shock mount without modding the frame and that helped with stock flex a little. Ounce I removed the bottom shackle it went back to climbing like a champ. So good product and idea but I didn’t have much luck for my limited parts and experience.

May have body roll issues.
They definitely give more flex to the suspension but have a slight issue with body roll.

Best cheap upgrade.
A lot of things I read said these doesn't work on the front of a trx4m. They do. I still have a stock servo maybe that's why. This is the best and cheapest upgrade I've done to my little truck.

Packaging mislabeling issue
I ordered the Flex Blade kit for the TRX4M but received the Rock Light Kit with Controller instead. Package was labeled incorrectly. (Note:I am disabled and would have to drive a distance to get to a UPS drop off site to return for replacement, provided others aren’t mislabeled as well.) UPDATE: Injura reached out to me and after looking into the issue, they made sure to remedy the situation and sent me the correct item I ordered. Great customer service on their part!

Mad Flex With These
Super easy to install, brings everything you need and some, which is great for extra parts. They dramatically increase articulation. Unfortunately for the trx4m it's limited to the interference that it has with the steering servo, but it still helps. The top flex blades aren't necessary, like other people have mentioned, but I put them on since it moves the position of the shocks, I think it does help a little.

Troppo costose ... per la pena.
Ottima fattura e rifinitura. Sono però calcolati per un utilizzo non specifico, ed in alcuni casi potrebbero avere problemi: controllare prima la compatibilità col vostro camion. Secondo me il prezzo di 18€ è esagerato, in quanto si trovano elementi simili se non analoghi a 1/3 del prezzo, che funzionano ugualmente. Mancano le istruzioni, serve occhio e volontà di ricercare le giuste info (scritte, video, foto, ecc) per un corretto montaggio ed utilizzo. Per il resto, funzionano ... anche se, non sempre al 100% delle potenzialità. Se potessi restituirle, lo farei e acquisterei quei modelli più economici. Metto comunque 3 stelle, come sufficienza in generale.
