  • Strength & Flexibility 
    We tackle one of the most common K-Swap issues with a new look and fresh idea. Our idler bracket and pulley kit was designed to take the guesswork out of a reliable belt tensioner system. 

    It's simple. Keep the OEM belt tensioner and alternator in place. Our bracket replaces the power steering pump, and our guide helps you find the right belt that puts it in the OEM system in the proper tension window. No more worries about your alternator falling, belt walking, or charging issues. We also altered the geometry to 

    We created two kits for the modern K-Swap. One for pretty much all engines sold in the USA, Japan, and Europe and another kit specifically for the common JDM K24A engine. 



    HYB-IDB-01-02
    This kit will be the most common setup used. Since it fits nearly all the known K-Series water pump housings and engines it will likely be the most popular. Known to fit the K20A, A2, A3, Z1, Z3, Z4 & K24A1, A2, A4, A8 means you will just need to measure your crank pulley to have a bolt-on solution. This kit requires no modifications to your water pump housing or any other accessory part.

    Improved hood clearance saving over 1.5" compared to a stock power steering pulley. It's also 0.5" shorter than the OEM EP3 idler bracket and pulley. 


    HYB-IDB-01-04
    This kit was specifically designed to fit the JDM K24A engine. This engine was never offered in the USA, however, has become very popular with engine importers. The HYB-IDB-01-04 includes a specific spacer bracket designed to be used on this engine only. From our research, there is no other engine like this in the US, therefore no other OEM option that we have tested worked. 


    Our kit improves hood clearance by being 1.81" shorter than the factory K24A power steering pump.  



    How to choose the correct belt:
    This kit does not include a belt; however, we do offer a bundle package that can include a belt if you choose. You will need to follow these steps to determine which belt to use on your specific engine. 

    1. Determine what engine you are using. (K20 or K24) 
    2. Determine if you are using AC or not. 
    3. Measure the outside diameter of the crank pulley. 
    4. Refer to the belt sizing chart to pick the correct size based on which kit you have and the diameter of the crank pulley. 



    *If your crank pulley is not listed, we do not offer a belt size. The process to find a belt is the same, you'll just need to source it on your own.

    PS & AC Delete Belt Sizes
    These belts are sized specifically for the Hybrid Racing Idler Bracket & Pulley Kit. We offer four sizes that fit nearly all K-Series engines without AC.

Comfortable, Simple, Reliable
Size: Tenkeyless, Pattern Name: Keyboard, Size: Tenkeyless, Pattern Name: Keyboard
This is a phenomenal product, and exactly what I wanted. I used to have wrist pain while gaming; I bought this, and then completely forgot that I used to get wrist pain while gaming. The foam is firm, but comfortable; it’s very supportive, but also flat and consistent. It’s cool, so my wrist never gets sweaty or hot just from using the wrist rest. Its rubberized bottom prevents it from moving at all while gaming. I’ve used it for about a year, and the foam has no indentation at all; in fact, there’s not noticeable wear of any kind. My one complaint, that I’ve seen in other reviews as well, is that the fabric skin of the wrist rest isn’t quite fit over the foam: there’s some extra material, and it can wrinkle slightly. Overall, I’m quite satisfied with the product! It’s completely eliminated my wrist pain, and I’ve gotten a year of use out of it with no problems so far. I’d say that’s more than worth the fair price, and I would buy it again without hesitation!

Very High Quality Memory Gel Foam
Size: Mouse, Pattern Name: Mouse
Firmness is pretty solid, this material is high quality. This isn't that kind of foam that will start loosing it's shape after a year or two, this is a firm gel like substance and it's pretty comfortable. The color is black as I expected, it's shape is rectangle just like in the pictures, it's appearance is as described. The only think is that they do use a polyester cover, which does appear as though it may wrinkle over time, and it will likely not outlast the Gel Foam inside. Like I said though the Gel Foam is legit Gel Foam, I have heard these claims before only to find out that it's something far cheaper, that's not this.

Awesome
Size: Full Size, Pattern Name: Keyboard, Size: Full Size, Pattern Name: Keyboard
If you spend more than a few hours a day at your keyboard, stop what you’re doing and buy this wrist rest immediately. I was starting to feel serious strain after long typing sessions, and this simple accessory has completely eliminated the discomfort. It’s a true game changer for desk ergonomics. The material quality is phenomenal. The memory foam (or gel) is perfectly supportive—it’s soft enough to cushion my wrists but firm enough that it doesn't flatten out or lose its shape, even after weeks of heavy use. The non-slip base is also fantastic, keeping it anchored exactly where I need it, no matter how intense my typing or gaming gets. What I appreciate most is the immediate relief. The height and angle are spot on, positioning my hands and wrists in a neutral, comfortable alignment. The reduction in pressure on my carpal tunnel area was noticeable within minutes. I can now work for extended periods without the usual aches or stiffness. This is a simple, high-impact product that vastly improves quality of life at the computer. It’s durable, comfortable, and absolutely essential for wrist health. Worth every penny for the long-term comfort it provides!

Pair with HyperX Keyboard Rest to complete the look!
Size: Mouse, Pattern Name: Mouse
Soft, comfortable, doesn't slide around, even on my XL mouse pad. Cool to touch which is nice. After a year of use, fabric on top becomes slightly loose and bunches up when moving wrist around.

Well worth it
Size: Full Size, Pattern Name: Keyboard
Very comfortable and robust. This definitely looks and feels like a premium item. I had bought a few alternatives that were cheaper and they fell apart quickly. This one seems to have pretty resilient stitching and the fabric doesn’t bunch up which could cause a tear. The base has a non slip texture so it’s not going anywhere without some force. The cooling feel is a nice touch too.
