Compare the Redcat RER43566 steering drag link and RER12651 front CV stub axle. Learn which spare part fits your RC vehicle and the key trade-offs.
Quick answer
Choose the RER43566 steering drag link if you need a replacement for a VERTEX 10 WIDE. Choose the RER12651 front CV stub axle set if you own a WENDIGO, MARKSMAN, or WENDIGO KIT. The two parts are not interchangeable.
Why compatibility matters more than price
Both parts are genuine Redcat Racing spares, but they serve completely different drivetrain locations. The RER43566 is a steering link that connects your servo or bellcrank to the steering knuckle on the VERTEX 10 WIDE. The RER12651 is a front axle component that transfers power from the differential to the wheel on larger trail trucks. Installing the wrong part can waste time and may not physically fit.
Price difference is small — the drag link costs about $5.91 and the stub axle set about $7.49 — so your decision should be driven by vehicle model, not cost.
What the catalog doesn't tell you
Redcat does not publish detailed specifications like thread pitch, spline count, or material hardness for these parts. If you are unsure which part your truck uses, check your owner's manual or measure the old component before ordering. The RER43566 is exactly 86.5mm long, so you can confirm fit by comparing that length to your current drag link.
The RER12651 comes as a pair, which is helpful if both front stub axles are worn. However, the listing does not specify whether the set includes hardware such as pins or clips — you may need to reuse or source those separately.
Trade-offs at a glance
- RER43566 – Steering drag link: A single 86.5mm link that replaces the steering drag link on the VERTEX 10 WIDE. Low cost and simple to swap, but only fits one model.
- RER12651 – Front CV stub axle set: A pair of front stub axles that fit WENDIGO, MARKSMAN, and WENDIGO KIT. Broader compatibility but requires more involved disassembly to install.
- The key trade-off: Narrow model fit (RER43566) vs. wider vehicle compatibility (RER12651). Choose based on your RC model, not on price or part type. Always verify your vehicle model before ordering — these parts are not interchangeable.
Product facts at a glance
- RER43566: RER43566 is a single steering drag link, 86.5mm long, designed for the VERTEX 10 WIDE. If your VERTEX 10 WIDE has a bent or worn drag link, this exact-length replacement restores accurate steering without guesswork.
