Take the guesswork out of your next LS Swap with this radiator hose kit. After performing multiple LS swaps, we decided to offer this kit to help enthusiasts avoid the frustrating process of finding the correct radiator hoses. This kit uses high quality Gates hoses and is designed to be used with a LS1/LS2 style water pump and a dual pass radiator (both inlet and outlet fittings on the passenger side). The following parts are included in this kit:

1. Gates 1-1/4" upper radiator hose with constant tension clamps
2. Gates 1-1/2" lower radiator hose with constant tension clamps

Please note that the heater core hoses are not included. If you need these hoses, please check our other listings.

Notes: 
  • Upper radiator fitting MUST BE 1-1/4" and the lower fitting MUST BE 1-1/2" in diameter.  If your radiator fittings are different, please contact us and we can provide other options.
  • Some minor trimming will be required.
If you are LS swapping your truck and need a custom kit, feel free to message us and we can assemble it for you.
