SlimLine Oil Cooler System for H-D Sportster

Now including a Jagg 4500 HyperFlow sandwich adapter for comprehensive fitment of air-cooled Sportsters (1986-2022).

Originally designed for Harley-Davidson Motorcycles, the Jagg SlimLine has become the popular choice for riders on all brands who demand exceptional performance and a stealth unencumbered appearance. Smooth end caps help this cooler blend in with the frame and hardware for a clean, streamlined look.

The cooler mounts to the left frame down-tube, spaced away from the frame to allow airflow to both the oil cooler and engine's cylinders. The cooler is mounted to the frame using unique, highly durable, Uralite mounts which have a shock-absorbing effect and clean styling. The SlimLine Oil Cooler's six-tube, two-pass design offers three-times the cooling surface than our closest competitor. Special in-line turbulators add to the cooler's efficiency with minimal oil pressure loss or restriction.

Jagg's unique offset oil filter adapter with Viscosity Regulated Flow provides an easy access point to the bike's oil supply for the installation of the oil cooler. The sandwich-style adapter is machined from billet aluminum and then hard-anodized to a satin black finish. The adapter installs between the bike's stock oil filter mount and the oil filter, and is designed with the same HyperFlow Technology as all Jagg components to ensure great performance as well as great flow characteristics.

The SlimLine Oil Cooler System is supplied complete with all necessary hardware and detailed, easy-to-follow installation instructions.
