SpeedFactory No Notch H-Beam Long Rod and Vitara Piston Combo D16This is a combo package for SpeedFactory Racing No Notch connecting rods and Vitara pistons for the D16 engines. This combo will bring the compression of the Vitara combo up to 8. 8: 1 as opposed to the standard length rod which yields 7. 8: 1 compression. Proudly introducing the new SpeedFactory Racing D16 Vitara Spec No Notch Long Connecting Rods! Vitara piston turbo D16 builds are one of the most popular 300 500hp street Honda setups out there.

This is a combo package for SpeedFactory Racing No-Notch connecting rods and Vitara pistons for the D16 engines. This combo will bring the compression of the Vitara combo up to 8.8:1 as opposed to the standard length rod which yields 7.8:1 compression.

Proudly introducing the new SpeedFactory Racing D16 Vitara Spec No-Notch Long Connecting Rods!

Vitara piston turbo D16 builds are one of the most popular 300-500hp street Honda setups out there. Very cost effective, fun, and relatively simple to build. One thing that has always been frustrating with these builds is having to use standard length off-the shelf rods that are low compression, unnecessarily large and heavy, and require the usual block and girdle notching to use. Custom longer rods were then introduced that fixed the deck height/low compression issue, but you still had to deal with the tedious and time consuming task of block and girdle notching. Time to kiss those days goodbye!

Introducing the ultimate rod for these setups – lightweight, strong, and clears both the sleeves & girdle for unrivaled ease of use.

Optimized specifically for Vitara D16 builds they offer high strength and quality at an affordable price. The custom rod length brings the Vitara pistons up to proper deck height which gives higher compression, increased efficiency, and better spool time while being substantially lighter than other similar rods on the market.

The 2-piece forged 4340 chromoly construction provides outstanding strength and quality. Each rod is heat-treated, magnafluxed, CNC machined, and shot-peened to stress-relieve the metal. The rods have precision alignment dowels to positively locate the rod cap, maintain big end bore size, and eliminate cap walk. They feature bronze alloy pin bushings for floating wrist pins and come standard with 220,000 psi rated 3/8” ARP2000 rod bolts. Instructions and ARP Lube are included.

- Forged SAE 4340 Chromoly Steel

- Bronze alloy pin bushings

- Multi-stage heat treated

- Shot peened to relieve stress

just get it and stop second guessing
Color: White, Color: White
I reallllly love this chair. I almost talked myself out of it because of some of the bad reviews here and there but i’m glad i listened to a majority of the good reviews, because this chair is perfect. shipping: it was super fast. it came 5 days earlier than expected. I got it on a Monday when it said it’d be here on Friday packaging: double boxed and bubble wrapped. Didn’t find any dings or scratches on anything. all parts were there including instructions assembly: my boyfriend put it together in 40 minutes. We didn’t have any issues zipping up the back cover like other reviews said and he said it was easy instructions to follow, and easy to put together. size and comfort: it’s bigger than the pictures let on! I’m 5’3 135lbs and feel like I’m sitting on a giant cloud. The comfort is 10/10. I just had a chair with basicslly zero butt cushion which i cannot have while working from home 8+ hrs a day in a chair. Comfort was the most important for me and I finally can’t feel the flat seat under me. I can’t express how comfy it is. Functions: can move the arm rests up and down. adjust the back to tilt all the way back to a sleeping position or fully upright which i didn’t even realize was a function! The only thing with the armrests; if you’re wanting your pet on it (like advertised) when the arm rests is put down there is a big gap that isn’t comfortable for animals (as pictured) so I have to put a blanket or pillow there for my small dog to lay comfortably. I’m obsessed with the fact I can sit cross legged, normally, laying down, sprawled up, or legs up. I have room to sit however I want, and the foot rests helps a ton with feeling even more comfortable. Overall, I’d get this chair 10x over. Not only do I work from home and spend hours in a chair, but I spend additional time playing video games so a good quality chair is very important to me. This has began to help fix my posture and back and neck issues. Get it!!!

If You Sit Weird Like Me… Just Buy This Chair
Color: Galaxy Black
I work from home and spend a lot of time sitting for hobbies like Legos, PC games, and crafts—so a comfortable chair is a must. I LOVE this chair so far. I’ve always struggled to get comfortable in traditional office chairs, and the ability to move around is really important to me. With this one, I can easily cross my legs, use the footrest to stretch out with my knees bent, or just sit normally. I’m 5’4”, so my feet don’t quite touch the ground, but that doesn’t bother me since I’m constantly switching positions anyway. I’ll probably add a small pillow for extra back support and maybe fold a blanket for a bit more seat cushioning. It’s comfortable overall, but after long periods of sitting, you might start to feel it. The black sparkle version is MUCH cuter in person, and I’m so glad I went with it. A lot of reviews say, “don’t think about it, just get it”—and honestly, they’re right. I debated for a couple weeks before buying, and I have zero regrets. Assembly was easier than I expected. I tend to get frustrated putting things together, but this was pretty painless. One tip: check inside the cushioned back piece for the extra headrest part—you’ll need it to attach to the hard back before inserting it into the cushion. Once I figured that out, the rest was simple. The chair is a bit larger than a standard office chair and can feel a little bulky depending on your desk setup, but I actually like the extra space since I move around a lot while sitting. It feels sturdy and well-made. It’s also slightly warmer than a mesh chair, which I personally love because I’m always cold. I am just happy to find a chair that feels comfortable like a recliner and movable like an office chair.

Great chair
Color: Pink
I love this chair! I use it for streaming and working on making jewelry! It’s very comfortable and I love that I can sit different ways in it! I can stream longer than I could in other computer chairs I’ve had! I definitely recommend this if you have to sit for a long time but like to sit in different positions! The instructions were a bit confusing but I did figure it out! I have had to spot clean it a few times because of kids and pets but the material has held up! The back is very comfortable and supportive! I like that I can adjust it! Great chair for the price! It’s held up well and I like that you can adjust the back!

Good office chair for the money
Color: White
It is a good quality chair that is comfortable and aesthetically pleasing. The arms aren't necessarily big enough to hold our cat - but that's because he's fairly large by cat standards. The arm rests moving is definitely nice and provides lots of opportunities to 'setup the chair' in a way that works best for you. The instructions were relatively easy to follow (take your time and think it through to make sure you have everything 'aligned right' at first) and the chair is sturdy and holding up well.

Comfortable. Great Value for money. Easy to assemble. Great customer service.
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I've been looking for a new chair to replace a cheap $30 chair i bought off of Amazon last year that had been killing my back and shoulders. I wanted something in the $150-$200 range and settled on the M18. Shipping was a fast 3 days with Prime and the box arrived in great condition. All parts were separately wrapped or in their own boxes. Came with all hardware and nothing was missing. Assembly took me a little longer then normal because i have rotator cuff injury in my left shoulder so that arm is mostly useless. The most difficult part for me was attaching the wheels to the base. Other then that it was simple. Once the chair was assembled i sat in it for the first time and started making my adjustments with the recline feature, armrest level along with the headrest. Next i reached around for the lumbar support knob and tried to adjust it but with my bad shoulder i decided to just get out of the seat and turn it around and adjust it with both hands. After spinning the chair a round to get at the lumbar knob i noticed a large crack in the plastic in the middle of the back of the lumbar plastic piece. I had not made any lumbar adjustments yet so i assumed this is how i received it. The lumbar support comes preinstalled to the backrest so it either was damaged before or during the shipping process. Either way it was damaged before being delivered to me. The lumbar support still functioned properly but it was still broken. I decided to contact Sihoo's customer support that came along with the installation instructions regarding the damaged lumbar piece. I received a reply the next day and after sending them some more info about my order and a couple pics they shipped me a replacement part which took a week to arrive. I swapped out the damaged part and after owning the chair for a week so far i am really happy with my purchase. Im about 5'10 180lbs. At its highest height level my feet reach the ground comfortably flat footed. The backrest fully covers my back and the headrest adjusts very well to sit on the back of my lower head/upper neck. The armrests only go up and down....not forward and back or tilt inwards. This is fine for me as they are grooved to fit your forearm while sitting at your desk/keyboard. The armrests are also a soft cushioned rubber material...not a hard plastic. The mesh of the backrest and headrest are good material and seem well made. The seat is very wide and the cushioning is firm which i prefer. Usually more firm cushioning seems to last longer and hold its form. The base of the chair is VERY sturdy and made of all metal. My chair is on carpet and holds its position very well. As far as recline goes you can set it to recline all the way back, half way or lock the chair in the upright position. You can also adjust the resistance on the reclining feature. So that being said im very happy with my purchase. It arrived with a slight flaw which the company corrected in a fast manor and was very polite in their customer support. I personally don't have a lot of experience with many office chairs and have never used a high end chair($500-$1000+) chair before to make any comparisons. All my chairs for the most part have been from local stores like Staples or Office Depot. Id recommend this over anything they carry in this price range....and i went and looked at their products before buying this chair as well.
