Carrier bearing spacer for rear driveshaft

[Silvertruck]

Is anyone running a carrier bearing spacer to correct rear pinion and driveline angles on a taller lift?

Dana spicer and a couple other makers have them out...typically made from billet aluminum.

The AEV spacer lift comes with it. Maybe those guys who have this kit can comment. I would imagine the setup is good to go since AEV puts one out with their name on it.

Thanks for the quick reply. I’m not having any issues but seems like cheap insurance and way more economical than a full custom driveshaft.

Here’s the Dana part number, if anyone is interested.

Yes sir, I have an Evo 6.5” lift and they insist on using a spacer (they provide with kit).

But that two piece driveshaft has worried me from day 1. I have zero evidence that it would fail, was more so just personal preference of being a weirdo about it.
Ended up going with a Tom Woods one piece shaft with 1350 joints. She’s strong now

Found this one. John Currie makes good stuff. Seems like a no brainer.

Rock Jock Carrier Bearing Spacer

I bought the Rock Jock version for my Clayton 2.5" lift. Figured if AEV supplies one then someone knows what they are talking about. Not saying I needed it but figured it wouldn't hurt. I did have to drill out hole hole to the next size though to get the bolts to fit. You might not have to but just an fyi from my experience.

I am running the Dana Spicer spacer and got back about 1.75 degrees of pinion angle after 2.5 inches of actual rear lift. The spacer is 1 inch tall. For those using different brand spacers, it may be helpful if you include your spacer height. In addition, if it came with a lift, what size rear lift?

In my case, the spacer alone is not enough to provide the proper pinion angle so I will use adjustable upper arms to get the rest. The pinion angle after the spacer alone is 5 degrees and should be between 2 and 3 degrees. I feel the spacer is still needed as trying the get all the adjustment with upper arms alone would provide a bad axle side spring pad angle and it helps the shaft angle at the carrier bearing.

Just because you don’t have vibration doesn’t mean you have the right pinion angle. You may experience premature driveshaft joint failure if its off and you should check/correct it after a lift.

How much did the Spicer spacer cost, and where did you buy it?

It was about $34 from 4 Wheel Parts. It took a little time since I was the first person to ever order one from them and they had to establish pricing from Dana but it should be easy for the next customer.

Whose lift did you use? Did it come with rear UCA's?

I started off with a JKS lift that did not come with UCAs. I am now running Synergy springs and Clayton arms.

I just picked up the Rock Jock spacer. Is it as simple to install as it looks? Any pointers?

I did. Rock Jock. Cheap and came with lock washers. I highly recommend it to people lifting.

Super easy. If your truck is old hit the bolts with pb blaster night before.

Get on your back under the truck, take the knee opposite your strong hand and brace the driveshaft forward of the carrier bearing and install with new bolts.

It seemed easier than trying to f around with a jack under there, imo. It isnt heavy and takes less than 10min. Theres no surprises.
