Learn what the H10 Hydro Ram Steering Set includes, how it replaces worn front axle steering parts, and the key steps to install it correctly on your Vanquish H10.
Quick answer
The H10 Hydro Ram Steering Set is a direct replacement for the front axle hydro ram steering components on Vanquish H10 axles (compatible with VPS09010A and VPS09010B). Install it by disassembling the old ram linkage, transferring reusable parts, and reassembling with the new stainless pivot balls, ram ends, slide shaft, and drag link.
Why the H10 hydro ram setup matters for crawler steering
The hydro ram linkage transfers steering force from the servo to the front knuckles. Over time, pivot balls and rod ends wear, introducing play that makes steering feel vague and reduces control on technical lines. This set replaces those wear items with stainless components, restoring precision.
What’s in the set and what it replaces
The set includes four link stainless pivot balls, two ram stainless pivot balls, two stainless ram ends, one stainless ram slide shaft, one drag link, two M4 rod ends, two molded ram links, and hardware. It is a direct replacement for VPS09010A and VPS09010B, so no modification is needed. Note that the set does not include a servo or servo horn; reuse your existing hardware.
When to replace instead of rebuild
If your current linkage has excessive play, bent ram ends, or corroded pivot balls, replacement is more reliable than trying to tighten worn parts. However, if only one rod end is loose, you might get away with a partial rebuild—but the full set ensures all wear points are refreshed.
Step-by-step hydro ram install
- Remove the old linkage: Disconnect the drag link from the servo horn and the ram links from the knuckles. Keep track of shims and washers. Common mistake: losing the small pivot balls or washers—use a tray. Label or bag hardware by location to speed reassembly.
- Inspect the axle and servo: Check the front axle for bent or worn mounting points and ensure the servo horn is secure. Replace any damaged parts before installing new linkage. A worn servo saver can mimic linkage slop—test it now.
- Assemble the new ram links: Press the stainless pivot balls into the molded ram links and attach the stainless ram ends to the slide shaft. Use the supplied hardware and washers. Do not overtighten; pivot balls should rotate freely. A drop of thread lock on rod ends prevents loosening.
- Install the drag link and ram: Connect the drag link to the servo horn and the ram assembly to the axle. Ensure the drag link is straight and the ram slides without binding through full steering travel. Cycle the steering by hand to check for binding before powering on.
- Set steering endpoints: Power on and adjust your transmitter endpoints so the ram does not over-travel or bind at full lock. Listen for servo strain. Recheck endpoints after the first run as parts settle.
