### ⭐⭐⭐⭐⭐ Great fit and helps cooling a 550 motor
*by L***Y on June 14, 2025*

Perfect fit for my son's Mercedes 450 ride on. It helps cool the motor (550 size). I attached two of them using a tie wrap.

### ⭐⭐⭐⭐⭐ Fit is perfict for 1/10 550 motor
*by R***0 on July 4, 2019*

Easy install and looks awesome. Needed for those hot summer days. Price is great for a four pack. I lost a stock heatsink just from roll over, so now I have extras that fit better than the stock one that I lost.

### ⭐⭐⭐⭐ does a good job cooling but falls off
*by C***R on June 28, 2021*

i definitely notice a longer run time when running multiple batteries before heat cutoff. when driving conservative it stays on fine, but if i take it out to a park with proper jumps it does fall off a few times in a day. could probably toss a zip tie on it to keep it secure.
