Lift your crawler
These were easy to install and fit was perfect to help lift our RC Truck. It upgraded the performance from stock significantly. The injora products are great scale quality and and easy weight upgrade as well.

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.

Great shocks
I put these on my little rock crawler and they helped the stability a lot. But the brass piece at the bottom gets lost easily so I had to buy a new set. It would be nice if it came with a spare or 2

Superior quality.
If I were to base all other reviews on the quality of these rc-car shock absorbers alone, everything would either get 4 stars of these shocks would be rated at 6. The quality is superior given theyre intended use. They also work on 1/16 wpl trucks with a little modifying of the truck.

Love the LONG travel
Installed these on my TRX4M and they made a noticeable difference right away. The added brass weight helps lower the center of gravity, and the suspension feels smoother with better articulation over obstacles. The threaded bodies make it easy to dial in ride height, and they look great too. Just note they don’t come filled with much oil, so you’ll want to set them up properly for best performance. Solid upgrade for crawling—better stability and flex. ⭐⭐⭐⭐⭐

Nicht nicht getestet, soweit ich weiß muss man die Dämpfer eventuell erst noch mit Öl befüllen. Der erste Eindruck ist hervorragend!
