NEW! FFG F100 Coyote Swap H-Pipe Bulkhead Adapter Kit

Always Helpful

I learned about the booster push rod adjustment tool from a FFG YouTube video. I've replaced numerous master cylinders and never knew the tool existed. FFG always helps me with the products they sell and I appreciate that.

High quality as always

Glove Box Liner

Good quality - 5 Stars - Buy one

FFG Ford Truck Glovebox Liner

This is a very well made liner that should last for a very long time. You might not be able to put very much in it but it is a nice looking piece.

Billet aluminum door handles are high quality

These handles take this important exterior component to the next level. The aftermarket Asian built alternative just doesn’t compare to these.

Missing parts again with this order

I spent $3600 on a complete A/C kit and $500 worth of parts were missing. No under dash valance and no bulkhead connector. After calling 3 times I finally was told they were currently out of the under dash valance. They had no Idea that the valance wasn’t shipped and didn’t place it on back order until I called to inquire about the missing parts. I’ve spent a lot of money with this company and I like their products but they need to work on the order fulfillment process.

FFG Coyote Swap Transmission Shift Lever | 6R80 & 10R80

FFG Universal Gear Shift Sender Kit

I would have preferred giving a 5-star review, but only one piece of the kit was sent. Still waiting for the rest of the kit items to arrive. We'll go from there.

Steering Column Floor Mount Adapter

Quality finish and looks great!

Perfect Heater Bulkhead

This is the best heater bulkhead for Coyote swaps on the market! If you want an ultra clean Coyote install use this bulkhead right behind the engine on the firewall and your heater hoses will route directly to it (assuming you get the right connectors). Installed this in a '66 F100; I only purchased the bulkhead as I already had the other fittings. It came complete with everything needed to install including gasket, nutserts and standard nuts/screws depending on how you want to mount it.

Highboy fuel tank
