Hey RC enthusiasts, if you're looking to seriously upgrade your Traxxas Rustler or Hoss 4X4 VXL, these GPM aluminum rear shocks are the real deal! We're talking 102mm adjustable shocks made from quality 6061T6 aluminum that's both lightweight and crazy durable. They come with multiple spring options too - silver 1.5mm, orange 1.6mm, and gold 1.7mm - so you can fine-tune the suspension to match your driving style and terrain. The shock shaft is thickened to 4mm and smoothly polished for maximum durability, and they use high-concentration suspension oil for better cushioning and performance. The package includes everything you need: gold and silver springs, stainless steel round head screws in both 3x14 and 3x16 sizes, metal balls, and those important white Delrin washers (remember to place them outside the metal ball during installation!). These are direct replacements for stock part numbers 8361, 1664, 3765A, and 6864, fitting perfectly on your 1/10 scale Traxxas Rustler 4X4 VXL (67076-4), Slash 4X4 models, and Hoss 4X4 VXL (90076-4). The blue anodized finish looks seriously sharp on your RC, but more importantly, the performance upgrade is noticeable immediately - better handling, more consistent suspension action, and that professional feel that makes your rig stand out from the stock versions. Whether you're bashing around the backyard or hitting the track, these shocks can handle the punishment while giving you that customized setup that serious RC drivers appreciate. The build quality is exactly what you'd expect from GPM - precise machining, quality materials, and attention to detail that makes installation straightforward and the results impressive.
