Compare Redcat 710017 and 07166 on fitment, function, and price. See which part matches your Rampage model and what to check before ordering.
Quick answer
These parts are not interchangeable. Choose 710017 if you need the aluminum front lower suspension arm holder (B-block) for a Rampage Chimera SR, Rampage XT, or legacy Rampage R5. Choose 07166 if you need the center diff shaft for a Rampage Chimera SR or Rampage XT.
Function: suspension mount vs. drivetrain shaft
The 710017 is a structural mount that holds the front lower suspension arm in place. The 07166 is a rotating drivetrain component that transfers power through the center differential. They sit in different systems, so a failure in one does not mean the other needs replacement. Match the part to the symptom: sloppy front suspension points to 710017, while loss of drive or center diff noise points to 07166.
Vehicle coverage: one extra model for 710017
Both parts are listed for the Rampage Chimera SR and Rampage XT. The 710017 also fits legacy Rampage R5 vehicles, while the 07166 is not listed for the R5. If you own an R5, that difference alone decides the choice for the front suspension holder. For Chimera SR and XT owners, confirm the part number against your manual or exploded view before ordering.
Material and price trade-off
The 710017 is described as sturdy aluminum, which suits a load-bearing suspension mount. The 07166 is a steel shaft by function, though the catalog does not specify its material. At catalog prices, the 710017 is USD 11.21 (compared to USD 16.99) and the 07166 is USD 17.24 (compared to USD 24.99). The 710017 costs less, but that does not make it the right buy if your center diff shaft is the failed part.
Trade-offs to weigh before you buy
- Fitment coverage: 710017 fits Chimera SR, XT, and legacy R5. 07166 fits only Chimera SR and XT. If you have an R5, 710017 is the only one of the two listed for your vehicle. Check your model against the product title before ordering.
- Part function: 710017 is a suspension arm holder; 07166 is a center diff shaft. They are not substitutes. Diagnose the fault first, then pick the part that matches the failed system.
- Price vs. need: 710017 is the lower-cost part at USD 11.21, but buying it will not fix a broken center diff shaft. 07166 costs USD 17.24 and only helps if the shaft is the problem. Order by function, not by price.
Product facts
- 710017: Aluminum B-block front lower suspension arm holder; fits Rampage Chimera SR, Rampage XT, and legacy Rampage R5. It restores a secure mounting point for the front lower arm on those models, and the aluminum construction suits a load-bearing part.
710017 - 07166: Center diff shaft, part number 07166, sold as one piece; listed for Rampage Chimera SR and Rampage XT. It is a drivetrain spare, not a suspension part, so it only solves center differential issues on the listed models.
07166
