Why buy from R40 Diesel?

We are not your typical "used car lot". We are a Diesel Truck Dealer and Diesel Mehanic Shop. When we bring in a truck, it is gone through from the front end to the rear end, transmission and engine wise. When we are done, they are perfect. When you buy a truck from us, you have the peace of mind that it is going to run strong for years to come and you are not inheriting someone else's "headache". We specialize in Ford, Duramax, and Cummins.

If we don't have what you are looking for, we will find it and customize it to your preferences. For example, if you would like a Ford 6.0 Bulletproofed with an aftermarket Cold Air Intake, plus 5" Turbo Back Exhaust, we can build that for you. 

Another service we can provide is a complete diagnostics test for a truck you may decide to purchase from another dealer or individual. If you're unsure of the purchase you're about to make, bring it by our shop and we will run a test for you for the low price of $150. For this price, making your next large investment will give you peace of mind.

2006 Ford F350 Dually Lariat

Bulletproofed and has a brand new performance engine. This truck only has 94889K Miles with a brand new motor. The motor work was completed in September of 2015. The engine was pulled, the block sent to the machine shop, bored over .020, and new main bearings and cam bearings installed. Two new cylinder heads installed with .020 pistons with new rings and new connecting rod bearings. Bulletproofed with ARP head studs, new head gaskets and EGR delete kit, as well as remanufactured high pressure oil pump with STC fitting. 5 new injectors installed, new O-Rings and copper gaskets installed on the other three injectors, blue spring upgrade, new rear main seal, rear timing cover and front timing cover. A/C compressor is new, new orifice tube and evaporator. The turbo has been rebuilt and a 5 inch turbo back exhaust installed, it sounds AMAZING! This truck has crazy power, it flies, and can pull anything. There is a gooseneck hitch receiver in the dually bed. The truck is super clean and the Lariat package is in excellent condition; leather interior, wood trim, power windows and locks, and power seats. The interior has been very well preserved, with only one very small hole in the driver seat. The exterior has a sharp two tone paint combination and overall is in great condition. There are a few surface scratches on the dually fenders and the rear bumper has some minor damamge. All in all, this is a gorgeous truck with a brand new, bulletproofed, performance engine with low miles on the body, and maybe 40 miles on the engine. With over $12,000.00 invested in the motor, and price to sell at $16,900.00, this truck is a steal! The truck is located at 126 Azalea Drive, Destin, FL.
