Product Details

The Wiseco K480B125 is a Professional Series shelf stock forged piston set designed specifically for Chevrolet Big Block engines running the Big Chief 3815 cylinder head. Purpose-built for serious street/strip and all-out drag race applications, this set delivers the durability and precision required to handle extreme power levels in high-displacement BBC builds.

Each piston features a +15.6cc dome and a 1.060 in. compression height matched to the Big Chief 3815 head's combustion chamber geometry. The 4.625 in. bore diameter and dome profile work together to deliver the elevated compression ratios demanded by big-inch, naturally aspirated race engines.

Key Features:

  • Bore Diameter: 4.625 in.
  • Compression Height: 1.060 in.
  • Dome Volume: +15.6cc
  • Head Compatibility: Big Chief 3815 cylinder head
  • Alloy: 2618 high-strength forged aluminum for superior tensile strength and detonation resistance
  • ArmorGlide® Skirt Coating for reduced friction, quieter operation, and resistance to scuffing and seizure
  • Vertical gas ports for improved ring seal and combustion efficiency
  • Anti-detonation and pressure seal grooves for consistent ring seating under high-load conditions
  • Fully machined crown for precise combustion chamber geometry
  • Forced pin oiling to maintain wrist pin and rod small-end lubrication
  • Includes wrist pin (S726 – 0.990 in. x 2.930 in.) and Double Spirolox® retaining clips
  • Rings sold separately
  • Engineered, forged, and machined in the USA

Wiseco's Professional Series pistons are engineered without compromise for builders who demand race-ready reliability. The K480B125 shelf stock kit provides immediate availability with custom-level specifications, making it the ideal choice for high-displacement Chevrolet Big Block race engine builds utilizing the iconic Big Chief 3815 cylinder head.

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

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

Best price on the net. Shipping appears to be fast (just ordered product and recieved a tracking number) Smooth transaction.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!
