There’s are great they don’t pop out like the stock ones I also have the upper arms they work great same as the steering knuckles all the udr hot racing parts r great
Do not order Hot Racing front ends for the UDR! They have literally no customer service at all! I have exhausted every method to try and contact them but no response. These CVs will break easy, I do not bash, I only run on 4s, and I don't even jump my UDR and yet it breaks because it binds with the Hot Racing knuckles. Read my reviews for the entire Hot Racing front end parts here on Amain hobbies. I actually use my UDR and not just install these parts to look pretty in a display, stick to the stock or plastic parts. Bad product quality, NO customer service. Their entire front-end lineup is bad. But the rest of their products is good and and quality. Just avoid the front upper arms, front lower arms, steering knuckles, and CV splines.
Perfect fit using Vitavon upper and lower A-arms and shocks. Used Udder-Butter for lubing the splines. No binding. Nothing broken during first 6s run. Great axles for UDR upgrade.
Three reviews cover the Hot Racing front steel CV splined drive shaft for the Traxxas UDR (2). Two verified or reviewing owners report a good fit, no binding, and no breakage, one of them after a 6S run with Vitavon upper and lower A-arms and shocks. The third reviewer, using 4S without bashing or jumping, reports the CVs broke because they bound against Hot Racing knuckles, and also reports no response from the company's customer service. That reviewer advises avoiding Hot Racing front-end parts, though their comments on the upper arms and other front-end items are not specific to this shaft. Reviews disagree on durability and fit, and the sample is small.
- + Good fit with aftermarket A-arms and shocks
- + No binding reported in use
- + Held up in a 6S run
- + Stays in place, unlike stock shafts
- − Reported breakage under 4S use
- − Binding reported with Hot Racing knuckles
- − Customer service reported as unresponsive
- − Negative remarks on the wider front-end lineup
