35mm Boxxer RC Damper Upgrade

So I've finally come to the conclusion that it's time to upgrade the damper (Motion Control) in my 2014 Boxxer RC (26"). I know that it isn't a sophisticated or fancy fork, but I've been happy with it until now. However, I recently rode a Bos and a DVO back to back with mine, and I'm leaving too much on the table. I have no illusions of turning my fork into a $2500 monster by changing a damper, but the MC unit isn't up to the task.

It's simply not a controlled enough fork- I have the spring set appropriately to my weight,and I know what I'm doing with rebound and low-speed compression. I'm realizing that I definitely need high speed compression control to help me get the most of my travel, as well as having a more subtle low speed compression range than the MC offers (it can lock out my fork).

The fork is otherwise well cared for and receives regular oil and seal changes, and a full service at least yearly (not a park rat). I'm very comfortable working on my own suspension, and I'll be doing so to upgrade the fork unless there is a truly pressing reason not to.

I've come across units from both Avalanche racing and Fast Suspension, as well as the obvious Charger upgrade. I'm having a hard time finding any critical opinions of the first two, and I'm yet to be convinced that the charger is the second coming (it's good, but a pain to bleed). Hoping somebody here has experience with these and some opinions?

I would skip the charger IMO.

Have a boxxer WC. ran the r2c2 damper and got it running pretty dang sweet.

Managed to snap the lower adjuster while doing lower leg oil. So picked up a charger damper. Install was easy.

But out of the box it has CRAZY fork dive on braking etc.. (Not enough low speed compression) and once i can dial that out, its WAY to stiff on the high speed compression.

I know that I can adjust the shim stack, and there are instructions in the serivce guide on SRAM's website...

But after the cost of the damper, plus the time to fiddle with shims, (maybe more than once?) and maybe still not get it where i want...

Yeah, I wish now that i had just gone with an Avalanche or similar damper. ( The charger was on the shelf in the middle of a trip when i broke stuf))

I wish I could provide more info on that front. But I am just, or more, curious as to how the Charger stacks up against the Avalanche, and how it stacks up with other aftermarket damper kits.

Thanks for the input. much appreciated

I think you summed up my concerns- that the charger damper upgrade still ultimately gives me a stock fork. Albeit a more sophisticated one. I'll still need to do shim stack wizardry to get it to work for me (im fat.and aggressive).

Go with the Avy upgrade.
