Rebuild your bent or scratched shocks with this genuine replacement Shock Shaft Set. These are the internal steel pistons rods that move up and down inside the shock body.
If you have landed a massive jump sideways or flipped your truck and noticed a shock is "stuck" or leaking oil, you likely bent a shock shaft. These replacements are made from precision stainless steel to restore the smooth damping action of your suspension.
Key Features
-
Stainless Steel Construction: Manufactured from tough stainless steel to resist rust and withstand the bending forces of heavy bashing.
-
Polished Finish: The shafts are polished to a mirror finish to glide smoothly through the silicone O-rings, preventing oil leaks and "stiction" (friction).
-
Precision Threads: Features machined threads on the bottom to securely hold the plastic rod end (eyelet) and the internal piston.
-
Dimensions: 3mm Diameter x 64mm Length.
Compatibility
This specific length (64mm) is primarily used on the Arrma 4x4 3S BLX & MEGA platform, but shock lengths vary by truck model (Granite vs. Senton vs. Vorteks).
-
Arrma Vorteks 4x4 3S BLX (Standard Rear Shaft)
-
Arrma Senton 4x4 3S BLX (Often used on Rear)
-
Arrma Granite 4x4 (Check Manual - Granites often use longer rear shafts)
-
Arrma Big Rock 3S (Check Manual - often uses longer rear shafts)
Important: Measure First! Arrma makes shock shafts in 60mm, 64mm, and 68mm lengths that look nearly identical.
Check your manual or measure your old straight shaft (end to end) to confirm it is exactly 64mm before ordering. If your shaft is 68mm, you need a different part number.

(2) Stainless Steel Shock Shafts (3x64mm)
Installation Advice
Don't Ruin the Seals: When installing a new shaft through the bottom of the shock body:
-
Lubricate: Dip the threaded end of the new shaft in Shock Oil before pushing it through the O-rings. Pushing dry threads through the rubber seals can tear them, causing your brand-new shock to leak immediately.
-
Thread Lock: Use a tiny drop of Blue Loctite on the nut that holds the Piston inside the shock (if applicable) or on the rod end, but be careful not to get any on the shaft itself.
Tech Tip: Replace the O-Rings: If you are replacing the shaft because it was bent, the bent shaft likely stretched or damaged the rubber O-rings in the seal cartridge. It is highly recommended to rebuild the seals at the same time using the Arrma Shock Seal Set to ensure a leak-free build.
