It upgraded the performance from stock significantly. The injora products are great scale quality and and easy weight upgrade as well. Review: 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. ## Features - [New Design] Brass bottom rod end, lower centre of gravity and improved stability. - [Superior material] CNC machined aluminum shock bodies, improves the performance of the RC car. - [Attentive Matching] Compressed Size (eye to eye): 42mm (1.65in), Maximum Travel: 17mm (0.67in), Spring Length: 45mm(1.77in), Spring Thickness: 0.45mm 0.5mm, Each Weight: 8g (0.28oz). - [High Performance] Threaded shock bodies for quick pre-load adjustments, telescopic design for maximum travel.
