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.

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

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!

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

Good but take some adjusting
Good product for max flex but they take alot of adjusting and testing to get them right. really wish injora products came with instructions. I see people saying it didnt work for their high trail but it worked for my f150 HT. i dont use the lower fronts because they hit the steer link and i lost like half my turning radius. rear shocks came loose and lost the bolt so now i use orange locktite especially on the ones you need to leave alittle loose for the movement.

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.

One of the best mods you can get for maximum flex!
These do so much for the price, they are great quality and it is a game changer for more flex. I got a set for my comp crawler and liked them so much I got them for my bronco. They work a lot better when you don’t have fenders in the way but they still make a difference. One thing to note is they do not work to well on the front.

Not worth it
This kit is a good idea and looks good but doesn’t function well with the rig as a whole. What I mean by that is the top mounts hit the shell (the body) so the shell doesn’t clip in very secure and falls off sometimes. The front lower mounts interfere with the steering knuckles so you can’t turn as sharp anymore. And the steering servo prevents the front axle from flexing anyways so the these mounts don’t increase front axle flex at all making this kit pointless. The only thing of this kit that actually works is the rear lower mounts which do allow the rear axle to flex more. Due to all of these set back it’s not worth the price. Save your money and spend it elsewhere.

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.
