Two isssues however, 1) if you buy a set of 1.6's and 1.7's - they have no markings on them to tell you which is which, so don't mix them up. 2) They are the same size as the stock pistons - so ya, they are a little smallish inside the shock body with the same "blow by" as the stock pistons. I wrote them to tell them to measure up a set of Avids, so we'll see if they improve. They offer a ton of different sizes and hole combinations, even tappered pistons. Oh, and they took 4 weeks in the mail.
that's cool that they drilled out some holes for you but you can do they same on your own with any pistons:

GMK Supply "Hole Thing" - Metric Shock Piston Drill Set
[GMK0108]

But having blow by in the shock makes them worthless like the stock pistons

my .02 cents

I hear ya. I tried to make my own and the holes were kinda oval and in the end I made a mess of them. A new set of stock pistons was $12, these custom ones were $16 - and they were the 1.6 & 1.7's I wanted. Had I known they would be the same fit as the stock ones, I'd have likely just gone and bought the Avids.

Worthless? hardly, not as precise? certainly.

I just thought I'd share my experience.

I hear ya but when you say you made your own holes and they were kinda oval it sounds like you used a power tool. doing it by hand is the way to go unless you have a bad twitch... then I would ask for assistance.

upgrading to Avid pistons is the way to go. they fit the inside of the shock perfectly with NO blow by. its an instant feel and well worth the money!

I personally went with the 1.6's and drilled out (by hand ) a set of 1.7's to be used in the rear. 40 losi front and 32.5 losi rears. 2 dot springs in the front and 1 dot in the rears

Thanks for the info on the pistons. I'll buy a set of the 1.1/1.6 and drill them. No reason to order 2x as many as I need. Was also thinking about trying 2 hole 1.5s front to mellow out the steering a little bit.

I tried both TLR & AE pistons, they are actually a smaller diameter than the stock Xray pistons, waaay too much blow by.

Xray pistons are too large and do not fit into TLR (not sure about AE) shock bodies either.
