Product Details

JE Pistons 270667 is a premium forged piston set engineered from 2618 aluminum alloy for extreme performance applications including professional racing, high boost turbo builds, and heavy nitrous usage. This 4-piston set features a 3.386-inch bore diameter, 1.130-inch compression distance, and 0.866-inch pin diameter with an inverted dome/dish crown design for optimized compression control.

Key Features:

  • 2618 aluminum alloy construction provides superior tensile strength for extreme boost and nitrous applications
  • Application-specific forgings ensure optimized, uniform crown thickness for heat management
  • Contact reduction groove minimizes frictional drag and improves efficiency
  • Accumulator groove increases top ring stability and sealing performance
  • CNC-machined side relief with lower support band adds critical skirt strength
  • Honed pin bores with double pressure-fed pin oilers for enhanced lubrication
  • Wire locks included for secure pin retention
  • JE ProSeal piston rings included with each set

JE Pistons are sold as precision-matched sets to ensure balanced performance. The 2618 alloy offers exceptional durability under extreme cylinder pressures and temperatures, making this piston set ideal for high-performance street, drag racing, road racing, and forced induction applications.

Shipped fast and accuratly within a week.

purchased two shocks for my truck, best price online , they were here within a week. I will definitely order from them again....thanks....

Best price I've seen online and the shipping is extremely fast. I would definitely use this site again for future automobile needs.

Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!

Excellent communication, quick, easy, and lowest price.

Best price for Rancho Shocks anywhere on the net! Ordered by phone and CSR gave me a better deal on shipping then the automated on site calculator.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

Glad I found Autoplicity.com. Big potential...<br><br>Ordered parts on Friday, missed 1st delivery attempt to office yesterday (Weds), but received today (Thurs). Little slow on the shipping, but not in a rush for these parts. We typically receive UPS pkgs in 1-2 bus days from Chicago suburbs to Metro Detroit. This took a bit longer, but again - it was not a problem & well worth the savings.<br> <br>Wish web-site would actually separate items for just my car vs all vehicle matches. Finding what I wanted was very difficult, but I'm very pleased with pricing & follow through. I've been back on Autoplicity 2 times now looking for add'tl parts for another vehicle, but have yet to locate them amongst the 100's - even 1000's of results that do not match. If finding them were easier & these add'tl items offer similar savings, I would have spent hundreds more by now. <br><br>If this is a new company, hopefully they can correct the advanced search option as well. Entering a part by vendor name should net results when the brand is listed on the home page & can be found in general queries. Even when I entered the part # for an item it shows no results, but again - searching several dozen pages, I am able to find the same part #. The savings were worth the headache it took to find the brake pads for my BMW, so I won't give up just yet. <br><br>Thanks Autoplicity! Here's to a potentially great future!!

Quick shipping. Good info on sttud will definitely irder again
