UPGRADE TO MAHLE PISTONS AS A GREAT SOLUTION FOR THE STREET AND TRACK

We have teamed up with Mahle once again to design the ultimate 1.8T stroker piston set. As with all of the other Mahle pistons we offer, these pistons come to the table with industry-leading features, OEM fitment, and OEM-like wear characteristics. These pistons are recommended for any high-performance engine build, as they offer unparalleled strength and longevity.

LEADING FEATURES

  • OEM fitment and wear characteristics
  • Quiet piston operation
  • Ideal compression ratio for mild to high horsepower applications
  • Durable forged pistons
  • German steel ultra-strength wrist pins capable of withstanding 800+HP
  • Lightweight piston design
  • Propriety Mahle low-expansion 142P alloy
  • Tight ring to piston groove clearances to reduce blow-by
  • Hard anodized ring lands to avoid micro-welding
  • Grafal anti-friction skirt coating
  • Oil squirter notches that ensure no piston skirt to squirter interference

In order to offer a piston set with the strength to withstand high power numbers and the longevity to last for thousands of miles, we started with the heavy duty forging that is used for direct injected applications that see higher cylinder pressures than the 1.8T. We then designed them with the specs that we have tested to work the best for the 2.0L stroker setups, using an 83mm bore and 92.8mm stroke. We offer these pistons with 9.25:1 compression ratio, which we have found to work effectively for street applications as well as higher horsepower applications.

To maximize power output, the clearances between the rings and piston have been brought in very tightly to reduce blow by. This is achieved by hard anodizing the top ring lands, which prevents micro welding which could be caused otherwise.

To maintain OEM-like wear characteristics, these pistons are coated with Mahle’s Grafal skirt coating. This coating reduces friction on the skirts, keeping them quiet and from wearing over time- extending piston life. The grey appearance of these pistons is due to a phosphate coating. Providing a lubricant film in the pin bores and ring grooves, this coating is essential for initial startup and break-in of the engine to prevent micro-welding and galling. Features like these are what allow these pistons to last for thousands of miles, just like OEM units.

In order to call these pistons the ultimate replacements for OEM, they need to fit like them. They are made with the correct oil squirter notches, which are necessary for stroked engines. These do not require any squirter clearancing or modification for fitment.

These pistons are manufactured from Mahle’s proprietary 142P alloy. This unique alloy offers the low-expansion characteristics of 4032 but strength near that of 2618 alloy. The low-expansion quality allows piston-to-wall clearances to be set tight, which allow the pistons to operate like OEM, quietly and smoothly.

Beneath the top ring and second ring lands an accumulator groove is machined, which provides a cavity where blow-by gasses can collect. This reduces pressure between rings, while virtually eliminating ring flutter and keeps top rings sealed securely against the bores.

Included is a set of performance piston rings, featuring a barrel-faced top ring, ductile iron, and 3 piece oil ring. These rings are designed to eliminate unnecessary drag, which reduces friction and increases power. Each set also includes high-quality German steel wrist pins and wire locks, which are 20mm in diameter. To match these pistons, we offer our IERTVA1 Tuscan and IERHVA1 H beam rods, both of which are a direct-fit.

Available in 83mm bore only. The 2mm overbore increases displacement to 2008cc when paired with a 92.8mm crank and allows you to bore and hone the block to the exact specifications required to ensure best results.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!
