- Hardened Steel Pinion Gears attached to motors
- Torque sleeves on both motor for even more low end powers

5 of 5 Awesome Upgrade! October 25, 2023
Reviewer: Rickie Wilson from Dover, PA United States  
After chewing through a pile of Chinese knockoff gearboxes it was time to upgrade. My son loves the extra speed of this 18v upgrade. Was super simple to install everything and get him back out ripping the yard up.

5 of 5 Awesome Kit! September 5, 2023
Reviewer: Dustin Dalziel from Grayslake, IL United States  
The batteries and motors are great and the instructional videos helped get a beat up old Power Wheels into top performing shape. The light kits are also easy to install and look great.

Reviewer: Matt Parker from Kent, WA United States  
Everything fit good. If two kids ride in it it blows fusses. With only one kids it works fine. But the battery dies faster then it did as a 12v.
