Why Wiseco Forged Pistons?

Wiseco forges all pistons in-house in the USA using proprietary tooling, giving them complete control over every stage of manufacturing — from raw aluminum bar stock to skirt-coated finished parts. Unlike cast pistons, which have no defined grain structure and can fail catastrophically under high stress, Wiseco forgings feature condensed, aligned grain structure that delivers superior mechanical strength, impact resistance, and fatigue life. Each piston is engineered to optimize the strength-to-weight ratio for maximum 2-stroke performance in demanding snowmobile applications.

The SK1211 is the ideal choice for a precision rebuild of your Ski-Doo Rotax 537-powered sled, offering OEM-matching fitment with the added durability of a race-proven forged piston design.

No shipping, and easy ordering. Can't wait to install.

easy site to navigate

So far so good with great prices and part availability. Update: My only complaint is that you are told your items will be shipped via a premium shipper and you pay for that, but in the end your items are actually shipped via a much cheaper shipping option. So you are not getting the shipping that you are paying for! This seams very dishonest to me, not sure if I will order from here again or not.

Easy shopping

Quick and easy.

man what a great price could'nt resiste

great

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Great price! Can't wait to see how the rest of the transaction goes.
