Anybody tried these? They are pretty new and I can’t find a review anywhere. Thinking about ordering them with a 4” kit if I get some good feedback.

I still haven’t seen any reviews. Mine are sitting in my shop floor. I’m still waiting on my lift before I put them in.

Did you compare the bar dimensions?

Are they a different diameter?

I don’t think the diameter is any smaller. I’ll measure mine tomorrow. Seems like they weigh 50lbs a piece so they aren’t much smaller. They do have 150lb less spring rate.

What I wondered is if it’s at4 torsion bars since they come pretty much leveled just a thought figured Gm would want to keep similar ride quality
nope. HDs have the exact same bars unless they are optioned with the snowplow/camper package.
The AT4 has the exact same height on the HD. Only the 1500s have the 2" level/lift

The dimensions listed in the order guide don't show a difference for the HD AT4.

For the 1500's they do show the increased height for the models that have the 2" factory lift.

(and the 'lifted' 1500's are still lower than any of the HD's)

So we’re these worth the investment on a already nice riding truck. Trying to see if it’s worth getting the better shock pack for damping control or stick these in with fox shocks
