In Memory of Tom Prufer (1940–2025): A True Craftsman of the Hot Rod World
On May 19, 2025, the hot rod community lost one of its most respected and beloved figures—Tom Prufer. For those familiar with polished frames, hand-fabricated parts, and the unmistakable smell of hot oil on cold mornings, Tom was more than just a builder—he was a quiet giant in the world of traditional rods and custom craftsmanship.

A Quick 95hp
So, you are the proud owner of a brand new Dodge SRT-4 and you love the sound of boost. Better yet, you love how quick your little four-door is. The only problem is … you want it to be faster. The need for speed is killing you and you will do anything and everything to get your adrenaline flowing. You have seen Mike Crawford and Shaun Carlson go down the track in their very fast SRTs and now you want the same thing.

Chasing Immortality: The 2026 AMBR Competition at the Grand National Roadster Show
The nine-foot AMBR trophy doesn’t celebrate excess. It rewards builders who understand proportion, restraint, and craftsmanship at the highest level—where every decision carries weight and every imperfection is amplified. Under the scrutiny of an expert judging panel, the 2026 AMBR contenders were evaluated on the fundamentals that have always defined America’s Most Beautiful Roadster: stance, line, finish, engineering, and an unshakable respect for roadster tradition. The margin between first and last place was razor thin, and the pressure showed in every detail.

Picture this: you’re cruising down a muddy backroad, ready to switch into 4WD, and nothing happens. You check your ESOF switch, slam it again… still nothing. The culprit? Not your transfer case, not your drive shafts—it’s the OEM vacuum hoses and steel fittings at your hubs, silently failing after years of exposure to heat, moisture, and road grime. Dry-rot, leaks, and rusted fittings strike when you least expect it, leaving you stuck and frustrated.
Enter the DIESELSITE 4WD ESOF Stainless Lines Kit—engineered to prevent this nightmare. Designed for 1999–2010 Ford Superduty models, this kit replaces those old, failing rubber hoses and rusty steel fittings with Teflon-lined, stainless steel braided lines that outperform OEM parts in every way. Whether you’re battling mud, snow, or the daily grind, these lines keep your 4WD system reliable and responsive every time you flip that switch.
