Designed for the ultimate in engine performance and reliability, Fuji Racings 14mm/12mm Head Stud Kit is a must have component for any EJ engine build where 450bhp+ power output is expected. It is essential to have the most reliable system for clamping the cylinder heads onto the block assembly to avoid the heads lifting under load at high levels of boost. The Fuji Racing 14/12mm Head Stud kit provides this peace of mind and cuts out the expense of cylinder head modification.

Now used in many engine builds from fast road cars to full on Group A rally cars the Fuji Racing 14/12mm Head Stud Kit is used by many engine builders/tuners of today. Replacing the 11mm Subaru cylinder head bolts with our 14/12mm precisely manufactured super high tensile, aircraft grade S99 steel stud and nut system offers many advantages when building your engine. With a tensile strength much higher than that of the OEM bolts and the increased stability provided by the Fuji Racing studs larger diameter when further combined with the more uniform clamping force provided by the stud and nut arrangement it is clear why so many successful engines run these kits!

Big Guy comfort at Lil guy price.
Size: 58W x 30L, Color: Lieutenant
Being a bigger guy I can't go to Walmart or Target and find pants at me it seems to be a problem I have no matter where I go. And going to a big and tall store is extremely expensive. But I found these jeans here on Amazon and I ordered them not only did they fit comfortably I could breathe in them I could move I could bend I could squat I've even gone to work in these and been comfortable throughout the day they didn't cling to me they were the most comfortable pants I had in a long long time. I wore these jeans so often that finally after actually a couple of years I wore right through them I like ripped right out of them but the material with everything I do and I work in shipping and receiving the material lasted a good two and a half years with constant wear and tear so the material is strong it stretchy to go with moving around and breathed with me kept me warm on the Dock,and they made me look good. Washed them regularly and that didn't wear them out either. Overall for any big boys out there a 10/10.

Great quality and price
Size: 44W x 29L, Color: Lieutenant
Very nice and great price. We only returned them because they weren’t the color or fit my husband was looking for. They were a gift so I based the purchase off his description. The jeans were exactly as described by the seller.
