1/10 scale GTR shocks represent the peak of suspension technology. The hard-anodized aluminum shock bodies are coated with PTFE for the slickest damping action available. Their 13 mm bores hold over 70% more oil than Ultra Shocks™ and their slick titanium-nitride coated shafts resist scuffing, increase durability, and eliminate "stiction." X-rings keep oil in and dirt out for smooth, consistent damping, and plush suspension action. Spring preload and ride height changes are as simple as turning the threaded spring collars, and the lower spring retainers are held on with a locking screw. Sold as a pair. Includes 30-weight pure silicone shock oil. Springs sold separately.
