Oil Coolers

Oil cooler and filter combination which ideally fills the empty space on custom generator/alternator engines. Of course it can also be installed in lieu of the generator on all HD motorcyles which were factory outfitted with such a device and don’t require a permanent charging system, e.g. magneto equipped motorcycles.

The Perf-Form easy change spin-on oil filter and cooler unit replaces the OEM  filter in front of the engine case. It povides mess free filter changes, good oil filtration and up to 10% cooler oil. With its Easy Change design the canister stays permanently mounted to the engine - no need to remove it to change the filter. Just take off the easy-access end cap to change the filter. Besides the indicated models Custom installation is possible, too, provided that the bike has a 3/4“-16 thread filter connection.

The cooler you can keep your oil, the longer its original cooling and lubricating properties will last...it‘s as simple as that. The American made Jagg Oil Coolers are engineered to perform and built to the exacting standards demanded by the world‘s top race teams and OEM manufacturers.
Universal use oil cooler which comes with four clamp pairs so you can mount it in on most models and in various positions. Features accented cooling fins.

Originally designed for Harley-Davidson Motorcycles, the Jagg SlimLine has become the popular choice for riders, who demand exceptional performance and a stealth unencumbered appearance. It features a six-tube, two-pass design for a large cooling surface. Special in-line turbulators add to the cooler's efficiency with minimal oil pressure loss or restriction. Smooth end caps help this cooler blend in with the frame for a clean, streamlined look. Universal mounting to the left frame down-tube for unrestricted airflow with unique, highly durable, Uralite clamps, which have a shock-absorbing effect and clean styling. Inclueded with each kit are clamp pairs in sizes 1-1/8”, 1-1/4”,
1-3/8” and1-1/2”, which should cover most applications.

10-Row oil coolers with extra cooling performance.

Works with all H-D models with front-mounted spin-on oil filters. Mounts between base plate and oil filter and avoids due to its offeset construction filter to sensor contact. A thermostat is incorporated.
There's a separate, optional anti-rotation device available.

This adapter for connecting the oil cooler is installed inline between oil filter and crankcase. The radially mounted oil cooler connections can be swiveled to accomodate oil line routing. However, due to the additional overall length, the oil filter may collide with any crankshaft sensors that may be present. A thermostat is incorporated.

The Jagg automatic oil cooler bypass acts as a remote oil thermostat to by-pass the oil cooler until the oil reaches optimal operating temperature.

Manually-operated by-pass valve which installs in-line of the two oil hoses to and from the cooler. In the open position, during warm-up, the oil will partially return to the tank without flowing through the cooler. As the oil temperature rises the amount of oil passing the cooler will gradually increase. With the by-pass valve manually closed all of the oil is forced to flow through the cooler. The latter is recommended only for high outside temperature.

This cowl replaces the stock oil cooler cover and extends over the regulator for a complete new look. Gel coated and ready to be painted.
