More info
Traxxas 30-Degree Caster Blocks are replacement left and right caster blocks set to a 30° angle for race-style steering geometry. They deliver crisper turn-in and a more responsive steering feel for track-focused setups and experienced tuners.
Sold as left and right pieces, the Traxxas 30-Degree Caster Blocks are designed to slot into your existing suspension layout as direct replacements. Use them when dialing in steering behavior for smoother cornering and better mid-corner control.
Why choose these caster blocks? They give racers a simple way to alter steering bias without major chassis changes. If you want sharper steering response and more consistent handling during aggressive driving, these 30° caster blocks are a practical upgrade.

Customer reviews
Did the job
They work fine. Snapped the new one when I hit a propane tank, but the factory one broke just as easily.
Perfect fit for Traxxas
Fit my 2.5 Nitro Rustler perfectly. Worked well, just had to sand down where those extra tabs were, I guess they're there to stop the c part from breaking in transit.
Break easily but cheap
These C-Blocks are the exact Traxxas replacement. Whoever says they're stronger is wrong, they're same as stock. They break super easily. While they're cheap to get, swapping them out can be a hassle bc of the E-clips. I have aluminum ones on another truck and they're great but pricey. Either stop bashing so hard or go aluminum, or you'll be replacing them all the time. Can't find these in RPM unfortunately. While they're essential, I'm replacing them on my street truck way too often.
