Step-by-step guide to replacing or upgrading the rear shock tower plates on your Redcat Vertex 10 or Vertex 10 Wide RC crawler using the genuine RER43547 carbon fiber part.
Quick answer
Installing the Redcat RER43547 carbon fiber rear shock tower plates is a straightforward upgrade that improves durability and reduces weight on your Vertex 10 or Vertex 10 Wide RC crawler. Follow these steps to replace the stock plates without damaging the new carbon fiber parts.
Why upgrade to carbon fiber shock tower plates
The stock plastic shock towers on the Vertex 10 can flex or crack under hard crawling, especially with heavier tires or upgraded motors. The RER43547 carbon fiber plates are stiffer and lighter, which helps keep your rear suspension geometry consistent and reduces overall chassis weight. This is a common upgrade for crawlers that see regular trail or competition use.
What you need before starting
You'll need a 2.0mm hex driver, a small Phillips-head screwdriver, and a clean workspace. The RER43547 kit includes two plates — one left and one right — but does not come with new screws. Reuse the original hardware unless it's stripped or corroded. Avoid using power tools; carbon fiber can crack if over-tightened.
Installation steps
- Remove the old shock tower: Use a 2.0mm hex driver to remove the four screws holding the rear shock tower to the chassis brace. Carefully lift the tower off, noting the orientation of the shock mounting holes. Common mistake: Forgetting which side is left vs. right — mark the original tower with tape before removal. Take a photo of the original assembly for reference.
- Transfer the shocks and hardware: Unscrew the rear shocks from the old tower using a 2.0mm hex driver. Slide the shock ball ends and any spacers onto the new carbon fiber plate in the same positions. Tighten screws just until snug — carbon fiber can crack if over-torqued. Do not use thread locker on the shock ball studs; they need to pivot freely.
- Mount the new plate to the chassis: Position the new RER43547 plate on the chassis brace, aligning the four screw holes. Insert and tighten the screws evenly in a cross pattern. Check that the plate sits flat and does not bind against the brace. Common mistake: Overtightening one corner first, which warps the plate. Final torque should be just past snug — stop when you feel resistance increase.
- Reattach the shocks and check alignment: Reinstall the rear shocks onto the new tower's mounting holes. Ensure the shock body moves freely through its full travel without rubbing the plate. Cycle the suspension by hand a few times. Common mistake: Crossing the shock wires or routing them too tight, causing binding. If the suspension binds, loosen the shock cap screws slightly and retighten with the suspension at ride height.
Parts used in this guide
