The factory pushrods in your 6.4 Powerstroke are designed for factory power and boost levels. As power increases, safeguard your engine with upgraded pushrods. And if you're rebuilding your engine, no time like the present for a big upgrade with a set of Manton Pushrods. These are a stock length pushrod, but built from superior materials and thicker walls for increased rigidity. Due to the increase in diameter, modifications will be necessary (see notes below).

11/32" STOCK DIAMETER VS. 3/8" DIAMETER:
The stock 11/32" diameter is the largest diameter pushrod that will drop right in without any modifications. However, by increasing the diameter of the tubing from the stock 11/32 to 3/8, the load is spread over a larger surface area without causing the pushrods to bind with the port of the cylinder head. 3/8" diameter will require the port hole of the head gasket to be relieved to fit the larger diameter. This larger diameter pushrod will provide almost 50% more loading capacity than a 11/32 diameter before beginning to deflect. Larger diameter is always a better choice when it comes to pushrods.

STAGE 3 PUSHRODS DEFINED:
Designed for mild to medium performance upgrades. Hard drawn 4130/4135 seamless chromoly tubing which is the highest quality available from mills and originally formulated for aerospace/aircraft use. This is a high quality pushrod which provides approximately 170,000 psi tensile strength. Suggested power range is from 400-750 horsepower, and is used for multiple applications such as towing, OEM replacement, sportsman diesel, and factory performance engines.

WHY A THREE PIECE PUSHROD:
In simple terms, pushrods transfers energy from the lifter to the rockerarm. If a pushrod is not correctly matched to the application, incorrect valve lift and valve timing can cause engine failure. With a properly matched pushrod you will achieve maximum horsepower and ultimate valve train wear.

To achieve the proper pushrod for an engine, you must decide the pushrod length, diameter, wall thickness, materials, heat treating and end configurations to match the specific engine components and application. This may seem like a fairly easy process but to accomplish this there are several things that must be considered. This is why Manton only manufactures custom modular pushrods.

  1. Each end in a pushrod must be compatible with its mating components. This requires the use of material that can function as a bearing and at the same time be as impact resistant as possible. As an additional benefit, this also allows for an unlimited amount of tip designs.
  2. With a modular pushrod it allows the flexibility to choose "unique" tapers for clearance issues. Also changing the wall thickness, diameter and tapering the tube will change the natural frequency.
  3. The column of the pushrod must be made out of a different material and heat treated differently than the tips. It must provide the strength to withstand the combined abuse of high engine speeds and cylinder pressure. By using a dissimilar material from the pushrod end, Manton is able to utilize any heat treat desired. In most applications, Manton uses a material that is commonly available 4130/4135 tubing.
In Manton's estimation, the only reason to ever produce a one piece pushrod would be because of the reduced cost to manufacture. But, Manton is in business to produce the highest quality pushrods available and for the reasons listed here they DO NOT manufacture one piece pushrods.

Great find!!
Color: White Rose Velvet, Color: White Rose Velvet
This thing rocks. I hope it lasts longer than my last gaming chair bc it was double the price. It arrived days earlier than estimated, is soft, comfortable, and really pretty. I did not love the instructions, but I figured out assembly without too much trouble. It reclines without falling over and goes up and down smoothly. My cats immediately love it, so I’m really happy! Let’s hope it withstands longevity.

Great and comfy
Color: White
This is genuinely such a good chair and super comfy, the assembly was a little confusing at first but it’s very simple once you get started. I’m 5’2 and it’s nice and big, you can sit however you want and although it is expensive I do think it’s worth it. You can fully recline down to sleep if you wanted as well. It’s nicely designed and sturdy. Definitely get it if you are thinking about it!!

LIFE-CHANGING. The only chair you'll ever want or need.
Color: Black
So... This chair has absolutely changed my life. I don't often leave reviews, but this is WORTH IT. I want one in every room in my home. Just as the other reviewer with the 'life-changing chair' title to their review: I've had 100% the same experience - especially as someone who sits 3,000 different ways w/ ADHD lol. So, in addition to agreeing with all those comments... I'll just add a few more thoughts here to further convince you: - I received the Cream/Teddy one as a Christmas gift and have literally have looked forward to sitting it in for work every. single. morning. for work. - I *ALSO* purchased a second one in the black velvet one to gift to my partner and his experience has also been 'life-changing.' (The black velvet is definitely sleeker looking, almost a teeny slippery, but just beautiful fabric. Love it. A note here: the fabric came with a crease, which steamed out no problem.) - I sit and edit websites and photo/video everyday, all day, for work, and I also spend a good chunk of my time gaming with my partner. (Now we are *both* very comfortable for those longer 5+ hour sessions.) - Previously I had tried the viral criss-cross chair and while it was cute and great at first, it just didn't hold up and started causing numb spots on my lower back after ~2 hours. Not an all-day chair at all. This one has solved all back issues for me! Size: definitely big & the back is quite a tall height but it makes you feel cozy, supported, *and* you can lean back, recline, adjust every little bit you like, have space for a velcro cat, sit criss-cross or 3,000 other ways as a ADHDr trying to sit all day, lol, etc. -- all things I was looking for in an upgrade. For reference, it fits someone 5'5" to 6"5" just as comfortably. I'd say it feels on the bigger side for someone under 6 foot, but personally, I love that. It's like a real adult chair - much needed if you sit for 6+ hours a day. Leg rest: Easy to flip out, I love using this so you can sit cross cross AND lean back, or just as extra 'accommodate the cat' space. Noise level: the arms clicking down/adjusting is loud, but I don't find myself adjusting them all that often. Especially when my cat claims this chair first, anticipating the start of our work day. Comfort level: 100% and 2.5-3 months in, it's still going strong and I'm more obsessed each day. *To the store: THANK YOU for making this chair, please never stop. *To the person reading this review: BUY IT. Let this be the review to convince you - your cat will take over the chair and you'll have to fight over it, it's that comfy. I mean, they know best, do they not?

Beautiful sturdy, cozy chair, BUT…..
Color: White, Color: White
Updated review. I was so excited to get this chair that I jumped the gun and wrote the review prior to spending more time seated. I only have one issue, which is the back bottom of the seat cushion. That’s a big deal. It appears so thick, fluffy and inviting, however, when I sat in it for a couple of hours it completely went flat in the back feeling like I was sitting on a board. I’m 5’4” 180 lbs, which means my feet don’t touch the floor so adding a cushion will elevate me a little more. I’m OK with that but it’s going to ruin aesthetic of the chair which is which is not ok. I do love the idea of this chair. It’s design and the color. I wish the seat cushion had a zipper, which would eliminate my issue. I’d say if you’re someone who has to spend a lot of hours in this chair, you probably won’t like it. I do like the reclining back and the foot rest. It is comfortable to lay back but that doesn’t change the issue in the back bottom of the seat cushion. I absolutely love this chair, I didn’t want to get up. It’s beautiful and cozy. Assembly was easy as I’ve assembled chairs before. I changed the wheels to a double roller blade easy on hard wood floors. I also scotch guarded the entire chair. This chair is sturdy and well made.
