Wössner is regarded by Europe’s leading motorsport engine builders as being the piston of choice when building an engine not only to perform but to withstand the stresses and duress of competition life. Wössner pistons feature a unique PTFE coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance then he might do on another make of piston.

This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. The crowns of the pistons are also polished to better resist detonation on a high-performance engine. Polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns. Price includes all piston rings and gudgeon pins.

PEC's own in-house design facilities are able to create many different components but for nearly 10 years now, it's our connecting rods that have helped set us apart from the competition in terms of availability, ease of fitment and size of the range.

Manufactured from forgings originally produced in Sweden, PEC connecting rods have offered engine builders and tuners a cost-efficient and yet high performing solution to a wide variety engine building problems.

H-Beam and I Beam section connecting rods are forged from AISI 4340 (En24) steel. Heat treated to HRC 35-38 and then shot peened for a higher fatigue strength. Small ends are bushed for a fully floating pin and big ends are fitted with high-quality ARP fasteners with different specification bolts available depending on the level of performance required.

PEC Connecting rods have been designed, manufactured and tested to the highest levels of scrutiny before being released to the trade and the public alike and their success record speaks for itself.

Perfect for small dogs like a Maltese
Color: Pig Balls
My small dogs love them, I have a small poodle and a small Maltese. These balls are a perfect size for their small mouths and have the cutest sound. We have had them almost a month and they haven’t got tore up yet.

Great fun for my small pup
Color: Egg Balls
My 15lb Pom loves anything that sqweeks so these little eggs are perfect for him. They are fun to throw since they bounce in all different directions. Considering how many you get it's worth purchasing

dogs have fun with them
Color: Smile Face Balls
They are a cute product. Do not give to large dogs. Made for tiny breeds. I dog sit and the dogs who are allowed to play with them go nuts when I get them out and give a sqeeze. The toys are holding up well too.

Love.
Color: Pig Balls
My frenchies love these and large enough not to worry about choking. Also the squeaker lasts longer than most of their latex toys so good or bad, I think it’s good.

Puppy Favorite!
Color: Funny Face Balls
Just the right size for a cocker puppy to fit in her mouth (3 mos. old) and squeak. She will do this indefinitely if I let her, lol! Seems to be very satisfying for her. I can only take so much of it but she loves them. Also bounces erratically when you toss it which she loves.
