Clear selection

Some of the highest quality pistons available on the market, Wiseco are uncompromising in their approach. With a Teflon coated piston skirt to minimise friction and wear on the cylinder bore to precision machined ring grooves with associated oiling modifications and improved piston crown design that promotes a more complete burn in the cylinder while minimising hot spots that lead to detonation.

Wiseco’s innovative Armor plating is applied to these pistons. This high-performance coating is applied to the piston crown, ring grooves, and piston pin bore.

The coating on the dome helps protect the piston from the damage caused by detonation, and will actually harden over time from the heat caused by combustion. This coating is also applied to the ring groove, and helps eliminate micro-welding of the ring, and improve wear of the ring groove along with improving ring seal. The coating in the piston pin bore improves wear, reduces friction, and eliminates material deformation of the lock ring groove.

Supplied with matching piston rings and wrist pins.

We Can Install This For You

We've designed our workshop services to be easy to book and pay for online. To book, you'll need to pick a date and time that suits you and then add the products you want to be installed.

Each workshop product is a labour price only. We've recommended some products on each page, but you can also find other compatible products at the bottom of the page. This way, you know exactly what product you're getting and how much its costing to fit.

Add both the workshop service as well as the product to be installed to your basket and proceed to the checkout. Once there, you can confirm your dates and process the order. Occasionally, some products may require confirmation, when this happens we will make sure we have the stock to fulfil the install and get back to you within 1 working day.

If you have any questions, want a bespoke installation or would prefer to book over the phone, give us a call on +44 (0) 203 795 0515 or send us an email at [email protected]
