We are proud to release this long-awaited masterpiece, all in 1 Latest revision 4, Ductile Cast CNC machined Integrated Main cap Brace that now utilises everything we have learnt and all evolution of our standard OEM overlay brace but this time we have included billet main caps and incorporated the block brace itself in a one-piece unit! As you know, block twist is the major factor contributing to blocks cracking where our standard original brace has helped immensely! You have heard or tried billet main caps, which do not offer block twist protection at all, they are also hard to pin down and stop them floating (near impossible)

The usual billet main cap is also usually too hard, the harder the better you would think! WRONG, hard singular main caps do not absorb or disperse energy and shock, it bounces it straight back into the crank and con rods, and unless you are running alloy rods, your bearing and rotating assemblies life is actually diminished, a connected main cap brace offers a ton of positives, including energy and shock disbursement, much better twist protection, and no chance of main cap movement, even less chance of cracking the main cap.

So with all the real data and testing, we have done over the last 10 years with our braces we figured it was time to release our latest brace creation in iron, available for both the RB26 and RB30 configurations.

*This brace is for the serious racers here, it’s aimed at 1000hp plus applications, although there is no issue running this big block of precision manufactured equipment in your everyday cruiser.

*This brace has excellent thermal expansion properties closely matched to your OEM Cast Iron block, with less machine work than our typical standard overlay braces. * 12mm or 1/2 inch bolt upgrade is required, Tunnel Bore is also required (as all blocks with aftermarket bolts are required)

 *Brace comes with bolt kit in any of the 4WD/ 2WD configurations for the RB25/ 26 type 4WD, and the RB30/28/25 RWD blocks and you can convert them all to 4WD or 2WD with the right chosen bolt kit supplied.

*Block face is O-ring aided for ease of sealing. The brace is blackened (surface treated) for corrosion tolerance.

So soft and amazing quality
Color: 12 - Light Beige, Size: Twin
I can't tell you if they're cooling or not yet. The weather took a turn for the cold so I haven't put them on the bed yet. But the quality..omg it's exceptional! These are insanely soft! Not slippery like satin but not scratchy like percale. They're like the best of both worlds..light as satin but nicely weighty like percale. I don't know what kind of sorcery this is but these are literally better than those 6-zillion count Egyptian cotton sheets that cost more than the GDP of a small nation. These are exceptional!! Soft as butter but still feel like they'll last a while and not let you fall out of bed like silk lol. When you fold them, they snap nicely. They seem to have a lived in look..like they'll never be utterly wrinkle-free but who cares..they're smooth, soft and supposed to be cooling. I never thought I'd find anything more comfortable than cotton sheets but these are even better. The colors are ok. Pretty basic but they are true to life..some others look different online than when you get them..not these colors online are accurate. This was a great deal and I'd recommend a thousand times over!

The softest sheets ever! 💙
Color: 05 - Dusty Blue, Size: Queen, Color: 05 - Dusty Blue, Size: Queen
This sheets quality feels great! It feels a little heavy but comfortable. I love the way it just drops. It feels cool to the touch, and so so gently on my skin! I previous had gotten a 100% cotton sheets from this same brand and it feels soooo rough on my skin, but this one is great! Best money spent! Bamboo material! I'm never going back! I got the dusty blue, in the photo is looks gray because of light but I love the blue color, it looks great!

Comfy, cool
Color: 01 - Dark Grey, Size: Queen
This is my first time buying rayon/ bamboo sheets, and now I finally see what I've been missing. Very comfortable, soft, and feel really nice against the skin. Nice for this price point too. I took off one star because they do tend to wrinkle quickly, so I have to readjust them every night before going to bed. Also be aware that oil from your skin and hair products tend to stain them very quickly, and the stains are not easy to get out. But I'm ok with that as a trade-off for the comfort!
