Why it matters

Stock plastic shocks are the weak point.

You jump, you land hard. The plastic shocks flex, leak oil, and bottom out. The truck bounces around and handles like a shopping cart.

  • β–ͺΒ Β Plastic flexes on landing. Plastic shocks bend on hard landings. The truck bottoms out and the chassis slaps the ground.
  • β–ͺΒ Β They leak oil. The plastic bodies crack and the oil leaks out. The shock goes mushy.
  • β–ͺΒ Β No adjustment. Stock shocks are fixed. You cannot tune them for different tracks or surfaces.
  • β–ͺΒ Β Aluminum shocks fix all of it. Rigid aluminum body, oil filled, adjustable preload. The truck handles like it should.
Split comparison: worn plastic shock on the left, shiny aluminum shock on the right
Left: plastic, flexy. Right: aluminum, rigid.
What it does

Four oil filled aluminum shocks, ready to bolt on.

Direct replacement for the stock plastic shocks. No modifications needed.

Better damping, better landing, better control.
01
Aluminum body

CNC machined aluminum body. Rigid, does not flex, does not crack.

02
Oil filled

Filled with silicone oil for consistent damping. No mushy feel.

03
Adjustable preload

Threaded spring collar. Tune the stiffness for your weight and track.

04
Set of 4

Two front and two rear. Replace all four at once for balanced handling.

Build & finish

The details that matter.

Cheap aluminum shocks have rough threads and leaky seals. These are machined clean.

CNC machined, oil filled, adjustable.
  • β–ͺΒ Β CNC machined threads. Clean threads that adjust smoothly. No cross threading.
  • β–ͺΒ Β Rubber seals. The oil seals keep the oil in. No leaks after hard runs.
  • β–ͺΒ Β Hard chrome shaft. The shaft is chrome plated. Does not rust, does not scratch.
  • β–ͺΒ Β Spare o-rings included. A bag of spare o-rings and mounting screws in the box.
How to install

Swap out. Four steps.

No special tools beyond a hex wrench.

01
Remove old shocks

Take off the top and bottom screws. Pull the old plastic shocks off.

02
Check the length

Compare the new aluminum shock to the old one. They should be the same length.

03
Bolt on new shocks

Line up the top and bottom mounts. Thread in the screws by hand, then tighten.

04
Adjust preload

Tune the spring collar to your liking. Start in the middle and go from there.

Care & safety

Four rules that keep shocks performing.

Aluminum shocks last, but a few habits keep them leak free.

  • β–ͺΒ Β Wipe the shaft after runs. Dirt on the shaft scratches the seals. Wipe it clean after each session.
  • β–ͺΒ Β Do not over tighten preload. Cranking the spring all the way down bottoms out the shock. Start in the middle.
  • β–ͺΒ Β Check oil level after a month. If the shock feels soft, top up the oil through the top cap.
  • β–ͺΒ Β Do not run on harsh surfaces. Rocks and curbs beat up the shafts. Stick to dirt tracks.

Will these fit my truck?

They fit most 1/18 scale monster trucks with 70mm eye to eye shocks. Measure yours before ordering.

Do I need to fill them with oil?

No. They arrive pre-filled with silicone oil. Install and run.

Can I adjust the stiffness?

Yes. Thread the spring collar up for stiffer, down for softer. Start in the middle.

How long do they last?

With regular care, a year or more. The aluminum body does not crack and the seals last.

Do they come with springs?

Yes. Each shock comes with a steel spring already mounted.
