the drivetrain is smooth as butter, before even being run in, and then the small things like steering posts key into the chassis. The arms also feel higher quality.

Yeah. I need to upgrade my diffs to HTD. My 7tr still has some resistance in the drivetrain. What's needed to fit the arms to a 7tr?

Just buy the new truck. The htd diffs in the 7tr are no smoother than the small diffs. If you want to use the new rear arms you will need suspension blocks from the 7r buggy. The down stop screws probably wont hit the chassis so they wont work either. Front arms should bolt on but you will also need the uppers, hubs, driveshafts, and camber/steering links from the new truck. ***The new arms are longer.*** They changed almost all the parts except shocks, rear hubs, engine mount, fuel tank, and steering rack. Center driveshafts and center diff (47t htd) are the same too. The old body and wing fit.

I confirmed the 7t stock body goes right on. Thanks Mugen for not changing that seriously.

For anyone thinking about buying 8t parts to upfit their 7tr: Just about everything else changed.

Buying a new one isn't an option for me since my 7TR is basically new. Just out of curiosity, what makes the 8T diffs smoother than the 7tr HTD?

Looks great! Were excited to be stocking Mugen now. I really need to put one together for myself for the experience.

The ring and pinion are different cut and the 8t pinion will not fit in the 7t.

The HTD's were not really meant to smooth out the drivetrain. The smaller pinion bearing in the rear changed that more. The HTD's are about gaining acceleration by changing the size of the gears internal to the differential and the 7TR has its own set of HTD's that can still be utilized for that.

Having ran a 7tr with both regular and ht diffs, save the $150 for an 8t.
