I want to upgrade to aluminum knuckles. I have seen the HR ones and like them, especially the fact that they come with metal pivot ball caps.
I currently have integy knuckles and the plastic caps are stripped. I cant tighten them nor can I take them out. The only option is to change them altogether.
Also do new ones from HR come with metal balls that go inside the knuckles?
Any other options that I should be looking at.
I do not abuse my truck and mostly its on road with a little bit of off road
I have the HR's and have never had a problem. However, I do mostly street runs. Some of the bashers have reported that the knuckles wear badly enough to pop out the pivot balls.
The HR's don't come with the pivot balls, but the stock balls fit. You can also spill more cash and get the Lundsford Titanium balls:

I run the HR ones and love them. They just come with knuckle, pivot ball caps and Allen wrench. Far as I remember been a min since I got them. A lot of people like GPM and GH also. I went with HR mainly for the knuckles with green pivot ball caps.
Regarding the stuck plastic retainer caps: Spray them with WD40 or other thin lube wait a minute, find a large flat screwdriver that roughly fits in the destroyed hex, jam the screwdriver in and then gently wiggle and try to unscrew them.
That worked for me with a stripped cap in my GPM knuckles.
I think Integy doesnt sell replacement retainer caps? But GPM does, you can try if their caps fits the Integy knuckle. Part-no is GPM ERV021DC. They are only $2.99. Cheaper as new knuckles and if they dont fit, you dont loose too much.
My experience with the HR knuckles are soso. I would not say that they are bad, but there are certainly better options available. My HR's started to pop the pivotballs after about a year, their were worn out on the innerside. The alloy retainer caps have the tendency to come loose every other run if you drive offroad. That can get quite annoying.
I have seen reports that some came with bad threads and we have one report from a user where one knuckle came without a thread in one hole, that thing was unusable.
For all this reasons, like better build quality, durabilty and available spare parts it would recommend GPM knuckles over HR.
Although the HR do look better.
Search the forum too, we have 101 threads about knuckles..
Edit: Part.no for the GPM knuckles is ERV021 and they are available in lotsa different colors.

integy knuckles worked well for me surprise surprise also rmp worked well for awhile(good for street use)untill they popped then every time a hit a jump or crash they kept popping and got worse my 2 cents

I like the looks and performance of the gh carriers .been through some abuse and no problems at all
I use the GPM ones on both of my 1/16 cars. Without a single issue. On my Merv for over a year now.

Thank you all.
CMD - J .... thank you especially for the details.
I was able to use a flat screw driver to pull them out. I also used my screw extractor kit. Its a kit will multiple drill bits but the threads are in the opposite direction. Its used to unscrew screws with stripped heads. It worked perfectly.
I am going to look into GPM and GH knuckles. Thanks
just a note: traxxas 7033x does not fit snugly on the integy carrier...there's a little play...not sure if this is normal or not...guess i'm the guinea pig...gonna order those gpm ball cap and see if it works...will let u guys know how it goes...
there are tons of threads on this:
here is one, was located a few posts down
You are going to waste time and money. Why don't you just order some new different aluminum carries

Yep good luck. Remember search here before buying!
u feel like an idiot if u don't ask...and then...u feel like an idiot if u do ask...either way...ur an idiot...but...in one version...u get to feel like an idiot by urself...in the other...the whole world gets to see how big of an idiot u are...choose...
Ha not that bad! I know I would have saved a few bucks!
