Universal Bolt-On Kits

F4 Universal Bolt-On Kits.
Please use the button below to access the order page where you can use the convenient dropdown boxes to choose the finish options you'd like. Please be advised, the polished option is not a very good value for your dollar. Polished metals require upkeep in the way of periodic repolishing to maintain their mirror shine and once these parts are mounted with fittings installed, repolishing them is next to impossible.

The bracket is reversible. I personally like it with the mounting holes hidden behind the filter, but you might like it the other way. Available space on your bike may dictate which way it goes.

Due to popular demand, we're now offering Universal Remote Oil Filter Kits. Available in simple bolt-on, clamp-on and weld-on configurations, these kits feature the same Made In America quality you've come to expect from us.

Our proprietary, patent pending filter mount uses a standard 3/4-16 filter nipple, has an od of 3" and fits stock Harley-Davidson filters as well as many others (Ford, Chrysler, etc). It's CNC machined from solid, aircraft quality, 6061-T6 billet aluminum and the bracket is precision cut on a CNC waterjet cutter. All hardware is stainless steel and all fittings are forged brass.

There are a number of options, including finish, hose size, bracketry, with or without spin-on adapter for the engine, and straight or 90°fitting configurations. Please take the time to look at all of them. We want you to get what you need the first time every time.
