Yes they work fine, get some shims though, you need to shim them as they are shorter.

Questions?? Info on the diffs in my FRE truggy

I just recieved my Matrix TR FRE today and I was wonder about the diffs in it. When I looked in the box I found the 3 LSD diffs with aluminum housings and 2 cross pin with plastic housings. I thought I read that the cross pin diffs only work well in the aluminum housings. Should I use the LSD style diffs up front and the cross pin diffs in the middle ,rear. Any input on which diffs to use where and what type of lubricant in them would really help. Also should I order the aluminum housings for the cross pin diffs. Thanks I just talked to sen direct and they told me they don't make aluminum cases for the cross pin diffs only the plastics one.

Use the plastic diffs with the cross pins. I am running 7, 15, 3 in my TR.

Colin thank you for reply, but I still have one more quetion. I only recieved 2 cross pins and 2 plastic cases. Do I use them in the front and rear or the center and rear as I read that alot of people run the LSD diffs up front. Thanks

Hmmm, I run them in all 3 places. If I had to, I would run the LSD in the front.

A few pictures of my TR Arena FRE. I am break-in a STS engine I had for a while. I am Going to use it as a practice mill. I currently have buggy tires and wheels installed so I don't wear out my more expensive truggy tires.

Default Ceramic bearings

Has anyone used any of the ceramic bearing in their Matrix TR. I'm thinking about ordering a Acer Ceramic bearing kit for my TR FRE. I just got it and I haven't started building it yet. I would like to go ahead and get Gene's cross pin conversion kit for the diffs also before I start building it. It would be a lot easier to put the ceramic bearings in when I'm building it then to go back and put them in latter. I could use my stock bearing as back ups. Thanks for your input Michael

Bearings are all prefirence, if you want them get them. Are those piggybacks from Cen's monster trucks? I have seen them a few times and think they might be worth getting for my local track. Can I have a part number? Thanks

The LSD works really well in the front with 90wt gear oil or 1000 diff oil. Right now Justin is using the pin diffs with 5/20/3.

The stock Cen bearings are great. We use Advantage Ceramic Bearings with the double rubber seals and they work great also. They are much lighter and roll very free. We do take both rubber seals out and clean the grease out. Then put light bearing oil in.

Malik sorry I don't know the answer to that. Gene and Robert will be back from the Truck Nats tomorrow so maybe one of them can answer that for you.
