XRAY Alu Shock Absorber Instructions


The premium XRAY aluminum shock absorbers are specially developed and designed to work with both the T2 (electric touring) and NT1 (nitro touring) platforms. These unique black hardcoated aluminum shocks are loaded with all of the features needed for today’s racing. Whether you need ultra-fi ne shocks for your lightweight electric touring car or ultra-reliable shocks for your nitro touring car, the new XRAY shocks have you covered.


The unique XRAY aluminum shock absorbers have interchangeable internal parts, giving you the option of installing 1 or 2 silicone O-rings. You can also choose between fully-adjustable 4-step pistons, or you can choose fixed 1-piece precision pistons. No matter what you choose, all pistons are ultra-true and round thanks to a very special mould design, resulting in ultra-free movement of the piston inside the shock body.


The XRAY aluminum shock absorbers come with all the necessary parts to build one pair of shocks (2 shocks). Springs and shock oil are not included and must be purchased separately.


• The aluminum shock body is precision CNC-machined on the world‘s most precise German long-turn CNC machine and every piece is robotinspected and measured to ensure maximum precision and tolerance. This is especially important with the inner diameter of the shock body to ensure that each one has an identical inner diameter to guarantee ultrafree shock piston movement. The aluminum shock body is machined from exclusive Swiss 7075 T6 aluminum ensuring maximum strength and rigidity. The shock bodies are black hardcoated using XRAY‘s own fully robotic colorcoating line with purpose-mixed color fl uids, ensuring a very even layer of color coating is applied to each shock body. After the coating process, every shock body is manually checked with highprecision callipers to ensure that the inner diameter of each shock body is exactly within the very stringent tolerances.

• The shock cartridge has been designed for self-centering shim(s) to hold 1 or 2 silicone O-rings, quaranteeing perfect alignment in the shock body. A finely-threaded aluminum shock lower cap secures the silicone O-rings and shims in the shock body.

• Finely-threaded spring preload collars are used to make ride height quick and easy. Even in very dirty conditions it is still possible to very precisely adjust ride height.

• The upper aluminum cap features a small vent hole that makes shock assembly very predictable and easy, since excess shock oil will escape through this vent hole ensuring that only the proper amount of the oil is inside the shock assembly. A super-soft silicone membrane supported by a miniature foam pad (inserted inside the membrane) provides proper dampening characteristics.



Choosing the adjustable pistons you can assembly the shocks to be easily externally adjustable. It is super easy, comfortable and smart. With just pulling out the shock rod out of the shock body to the fullest extended position the shock piston will lock into the shock body and turning the shock rod in the right direction the harde shock dampening characteristics will be adjusted while turning into the left position the softer dampening position is adjusted.

Using the XRAY‘s externally adjustable shocks allows the fastest and most comfortable shock dampening action directly on the car without any need to dismount the shocks and neither without the need to disassembly the shocks or exchanging any parts.



For 1/10 electric touring cars (such as XRAY T2) XRAY suggests using the 1 O-ring setup as a basic setup. The 1 O-ring setup will result in supersmooth action due to improved free movement of the shock rod, providing extra traction and damping. When installing 1 silicone O-ring, use one O-ring and one thin and thick shim in the lower shock body assembly. Note that using the 1 O-ring setup (as opposed to the 2 O-ring setup) may cause the shock to leak very slightly through the single O-ring. THIS IS COMPLETELY NORMAL. Regular servicing and maintenance is required when using the 1 O-ring setup to replace any lost shock oil.


For 1/10 nitro touring cars (such as XRAY NT1) XRAY suggests using the 1 O ring setup as a basic setup. Using the 2 O-ring setup ensures consistent damping throughout long finals, and less servicing and maintenance will be required due to less inherent oil leakage than the 1 O-ring setup. When using the 2 O-ring setup, the shocks will still work freely and smoothly but not as smoothly as with the 1 O-ring setup. When installing 2 silicone O-rings, there are two very thin shims between the O-rings to ensure that the O-rings fit properly in the lower shock body assembly.
