Fabtech takes their 4 in. Super Duty systems to the next level with the release of the Dirt Logic 4.0 Coilover Conversion. This bolt on Coilover conversion will transform the ride quality of the Super Duty while providing outstanding damping capacity for rugged offroad use. The Dirt Logic 4.0 Coilover is constructed with a stainless steel body and a NitroSteel piston rod for maximum corrosion resistance. This 4 in. lift Coilover Conversion is offered with Fabtech's Tubular Radius Arm or 4 Link Systems Radius Arm system features an offset tubular design with dimple die side plate for maximum strength. The 4 Link system replaces the stock Radius Arms for an improved ride quality both on and offroad due to a near zero caster change throughout the suspension travel. Both systems include a track bar relocation bracket to center the front Super Duty axle under the vehicle with the new lift height. Rear lift comes from a 5 in. lift block with bump stop relocation brackets. Rear Dirt Logic 2.25 stainless steel shocks are valved to provide a balanced ride to the Super Duty for the finest on road ride quality. These high end 4 in. Systems are the pinnacle of quality and ride performance for the Super Duty. Each system is a bolt on installation and comes with Fabtech's 5 year 60,000 mile warranty.

No bow tie
Color: Burgundy, Size: XX-Large
Perfect fit for my son he's 6'2" about 220lbs. He ordered 2XL . I would've gave it 5 stars but he did not receive the bow tie, and his prom is tomorrow! Now I gotta go out snd spend more money buying the bow tie separately.

Sharp suit
Color: Black, Size: X-Small, Color: Black, Size: X-Small
The quality of the suit is very nice. The material feels thick and does not feel cheap at all. My son and I were both very pleased with this three piece suit altogether. We went off of size recommendation and due to personal preference we both agreed if we weren’t already in time crunch we would’ve sized up one size. Still managed to make it work and looked very sharp. He is 5’10” 150lbs - size ordered extra small

Order 1 size larger.
Size: X-Large, Color: Blue White Plaid
Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.
