This is the heart of the most popular air-cooled stroker there is. EMPI's 94mm x 82mm piston and cylinder set (98-1957-B) is the matched four-cylinder kit that builds a 2276cc Type 1 when you run it on an 82mm stroker crank. Big bore, big stroke, one matched set — pistons, cylinders, rings, pins and clips.

Features

  • 94mm bore x 82mm stroke — builds 2276cc, the go-to air-cooled stroker displacement
  • Matched set of 4 — pistons and cylinders sized together
  • Includes rings, wrist pins and clips — a complete top-end set
  • Designed to pair with the EMPI 82mm counterweighted crank (00-8182-0)
  • Requires case and head machining for the 94mm bore (see Fitment)

Fitment

This is a build component, not a bolt-in. A 94mm bore requires the case cylinder spigots and the heads to be machined to accept 94mm barrels, and the 82mm stroke requires case clearancing. Built for Type 1 cases going to 2276cc with a matching 82mm crank. CONFIRMED: Type 1 cases machined for 94mm x 82mm. NOT CONFIRMED: stock un-machined cases, Type 4 engines.

These are quite large for a puppy
Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
These are advertised as puppy but I wish there were still different sizes for the different sizes of puppies. It seems extra small dogs are left out of alot of things. My older larger dog seems to like these but shes only touched it once because these are also quite hard. And my tiny puppy wants to chew these but theyre so big she cant even get ahold of it. I wish there were more options for very small dogs/puppies. Because they seemed to really like these and wanted them but just cant chew them...

I have two dogs that can chew through everything within a day. Not these, going on four days now, there are signs of wear and tear but still intact. The dogs love the flavor.

Dog is Happy!
Color: 3PC-Peanut Butter-Green, Pattern Name: Tough Dog Toys
My dog likes the bones, especially because they are peanut butter-flavored. The bones are very strong and well-made, so they are good for heavy chewers. By the way, these bones are very large for big dogs only!

They last for months
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
This is my second order of this product. I have 2 medium size dogs and they love them. The nice thing is a 3 pack of these is that they will last them for a few months.
