Hi, will this fit my standard Kraton 4s or are modifications required. Thanks.

Name: GPM Aluminium 30x30x10mm 20000rpm Cooling Fan - Blue
Brand: GPM Racing
SKU: GPM-XRTM051FAN-B
Price: 36.33 AUD
Availability: InStock

Hi Stephen, Unfortunately, the GPM XRTM051FAN-R is designed specifically for Traxxas ESCs and includes a custom mounting bracket that won't align with the Spektrum ESC on your Kraton 4S. However, the Yeah Racing Tornado 30x30mm Fan is a great semi-drop-in alternative! The 30x30x10mm size and screw spacing are an exact match for the ESC housing. To wire it up, you can either: Use a JST-to-JR adapter cable to plug directly into the Spektrum ESC fan port. Plug it straight into an open channel on your receiver box for maximum power/RPM. It moves significantly more air than the stock plastic fan and keeps ESC temperatures right down — I'm a big fan of them myself!
