chairpartsonline Heavy Duty Replacement Office Chair Swivel Tilt Control Seat Mechanism w/ 6" x 10.2" Mounting Holes - S2979-HD Black

This tilt bracket is just what you need to repair your cracked original bracket from whatever brand of chair that you own. The mounting holes on almost all chairs are pretty much standardized, so this bracket will fit without issue. It does have slotted holes, so there is room for adjustment if your chair is an oddball. No instructions are included, just the bracket in a thick plastic bag, but if you are attempting this you probably have a good idea of what you need to do already. The bracket construction is definitely better than stock, with a metal gauge at least two times that of the OEM bracket. Installation-wise, once you get the old bracket off the lift cylinder, you're set. Just screw this new bracket to your chair bottom and set it on the cylinder post. The problem is getting the old bracket off the lift cylinder post, lol. These tilt brackets use a taper fit between the bracket socket and the lift cylinder post; when you set it on the lift cylinder post it wedges itself in place and becomes almost inseparable. In order to release the bracket from the lift cylinder post, you can do a couple of things: 1. Use a pipe wrench and a hammer - grip the cylinder post with a pipe wrench, then use a hammer to whack the bracket in an attempt to spin it and break the wedge fit. or 2. Use a rotary tool and a cut off wheel to slice a slot in the tilt bracket's socket and relieve the tension on the wedge fit. I chose option two, see the pictures. Don't worry if you nick the lift cylinder post a bit like I did, it isn't a sealing surface and will be inside the new bracket's socket when you re-assemble the chair. You also might want to take the opportunity to clean and re-grease the swivel bearing in the bottom of your lift cylinder, my chair was kind of rough and slow on its swivel due to grooves that had worn into the two washers that the bearing rides in between, as well as hardened grease. I pulled the cylinder apart - there is an inner, sealed cylinder and an outer cylinder that it slides into. The washers and bearing sit on the tip of the inner cylinder's post, down in the bottom of the outer cylinder. I wiped off all of the old, hardened grease and re-greased it with wheel bearing grease. I also flipped over both of the washers so that the bearing now rides on the smooth, unworn sides. The chair now spins smooth as butter, just like the day I bought it. Use plenty of grease when you do this, that way the bearing and washers don't fall off the inner cylinder post when you reinsert it into the outer cylinder. You can also turn the chair's star base with the outer cylinder still in it upside down to make this step easier.

Way better than the seat control that FAILED from new in less than 2 yrs. Ordered to replace the seat control and my T3 Rush and it did the job. Installed in 5 min and fixed the wobble of the seat. Everything on this one is more robust than than the factory one from corsair. Good for the price!

I got this nice leather office chair a year or so ago. I guess it was manufactured for the big and tall market, but I got it because it was marked down. It is so big and heavy within a few months the tilt mechanism began to fail and eventually, the huge chair just flopped back and forth and I though one day it would just snap off like a stick and send me to the floor. I found this, it is very thick and very heavy. I installed it and have been using it for about 2 months now. I can tell it will hold up, if feels solid, and there is no lost motion anywhere in the tilt mechanism. The metal is so thick I do not think it will bend and I weigh about 200 lb. The old mechanism was bent in every direction . I wanted to add that I had no difficulty taking the chair off the mechanism, it is only held by 4 heavy duty screws. But I had a lot of trouble getting the mechanism off the stick. I was thinking I had to knock it off with impact from a hammer but that did not work. I read somewhere on the internet that you are supposed to put a pipe wrench or a large vice grip on the vertical stick. You are supposed to use your wrench to rotate the metal stick while you hold the mechanism still. One this old joint slips a little, all the friction is released and the mechanism just slips off, no problem. You may want to spray the socket with some WD-40 an hour before you do this. But it is very easy to separate it from your old tilt mechanism this way. I thought about this initially, but I was so afraid I would damage the surface of the stick because I though it was the hydraulic surface of the piston. It's not, the piston is inside this big silver pipe you are working with. A small scratch does not matter as it is not the surface that slips inside pressurized cylinder.

i'm a bit on the heavy side, pretty close to the advertised capacity of this product. yet this has taken care of me for more than 3 years and still going strong. it was easy to install, tilts well, adjusts well, and it holds me well, STILL without any creaking at all. sometimes when i just sit back, the adjustment lever will wiggle out, so it will tilt and i'll nearly fall out of my seat, but all that does is scare the b-jeezus out of me. i slide it back in again and i'm fine. it's good for a laugh and a jolt. i've never had any other brands so i don't have anything to compare to, but what i'm happy about is that i don't need to.

Bought this out of of need for my DPS Gaming 3D Insight Office\Gaming chair because the factory base broke at the cheap welds causing the seat to be very wobbly which was a potential safety hazard. This base was a direct replacement and perfect fit and so far appears to be an upgrade, only took about 10mins to swap out the parts. The chair is much more stable and comfortable now. Very happy with with this product so far!!
