Smooth Upgrade for TRX4M Crawling Performance
I installed the INJORA Brass & Aluminium 59mm Shocks on my TRX4M and TRX4MT, and they’ve been a fantastic upgrade. The long threaded design gives you plenty of adjustability, and the oil damping is noticeably smoother than the stock setup. I especially like the brass lower ends—they add a bit of weight down low, which helps with stability on steep climbs and uneven terrain. Build quality is excellent; no leaks or loose threads after several runs. Installation was straightforward, and they fit perfectly without any modifications. The added weight from the brass components improves traction without compromising articulation. Visually, they look great—definitely give the rig a more premium feel. If you're serious about crawling with your 1/18 scale RC, these shocks are a worthwhile investment.

watch for wrong parts, better once i got the right ones
i ordered these big ol shocks for my trx4m k10 to get extra travel and what not, got these this morning and they sent FACTORY shocks in an injora bag. im still gonna buy from injora but ive never had the bad luck of a bad shipment, might change review after the real parts show up way better now that i have the right part, super nice and bring lots of travel, surprised that they had fluid in em when i got em, although i do recommend keeping the factory front drive shaft on because my injora one would lockup at full travel

Beautiful operation
Got these on 2 trx4ms and on an hpi venture! The hpi venture 18 I had to space and use aftermarket screws.

Great product!
Shocks work great, will need new oil and bled before installation. Brass bushings are quality and a great value. Weight on the lower end helps to lower the center of gravity really helping with crawling. Great product!

Need some work but can be a great value
I very much like Injora products overall. These took some fussing to make reliable in my opinion. They stick after sitting and felt gummy overall, the heavy springs seemed to struggle with just the shock alone. They came with oil inside, at a bare minimum I would pull the bottom cap and lube the o-ring that helped tremendously. I also swapped to a premium shock oil and it smoothed everything out nice
