Worx+ Big Block Motor Upgrade Package
If you own a King Concepts machine, Husqvarna PG 680 or PG 820 (including RC), then your machine is ready for this upgrade! The Big Block is the upgrade the machine was designed for but never received in the factory.
The Performance Upgrade Package includes:
- The larger, 15kW Big Block motor
- A computer software retune
- All mechanical components to make everything fit
Get the Big Block Upgrade and knock out 5 days of work in just 4 days. Less time spent on the jobsite and more money in your pocket.
We estimate 1 week to complete the motor upgrade and any other necessary maintenance and repairs. We recommend coupling your Big Block Motor upgrade with a Wheel Kit install or Light Kit install.
