TIME MACHINE
Big billet wheels, custom suspensions and modern power plants—that’s what we’ve come to expect from a first generation Camaro. And while these items are great if that’s what you prefer, we just can’t help but love a car that stands out in a crowd, like this 1968 Camaro vintage street machine. Period perfect down to the slightest details, the black Camaro would have been the ultimate classic Camaro street machine in the late ‘60s and early ‘70s with its big-‘n’-little Cragars, Lakewood traction bars and nose-down stance. Claude Minor is the proud owner of this retro Chevy, but it certainly didn’t start out in this configuration.
IN WITH THE GOOD AIR
When a B16A-equipped CRX EF came into the Rage Performance shop for a Skunk2 intake manifold install, the crew dove into the job with a fury. With cameras at hand to document the swap (’88-’91 CRX) for your personal pleasure, the job took no time at all and the owner of this Honda is deliriously happy with the results.

Product Spotlight: DIESELSITE 17-Row COOLERMAX Transmission Cooler
Top-of-Market Cooling Power: The Last Transmission Cooler You’ll Ever Need
Rated at a monster 59,000 BTUs, this cooler doesn’t just compete—it sets the bar. Standard factory units limp along at 15k–30k BTU. Even most “heavy-duty” aftermarket coolers top out well below the COOLERMAX’s rating. That extra capacity can mean the difference between cruising safely at 180° or cooking at 240°. In the real world, that translates into drops of 50–60°, longer fluid life, and transmissions that simply last.

Why Transmission Cooling Matters
Heat kills transmissions. Plain and simple. Every year, trucks get sidelined—not because the engine gave up, but because the transmission cooked itself alive. You tow, you haul, you sit in traffic, and all the while your fluid is breaking down, seals are hardening, and clutches are begging for mercy.
At 200° your ATF starts to degrade. At 240° varnish is forming. Push to 260° and rubber internals are toast. Hit 295°? Game over. Slipping, burning, and the kind of repair bill that makes your wallet hurt worse than your truck.

Enter the DIESELSITE 17-Row COOLERMAX.

Built for Performance and Durability
The COOLERMAX isn’t just bigger—it’s engineered smarter. With a 17-row stacked-plate core for maximum surface area, -8AN inlets, 316 stainless adapters, and universal mounting brackets, this unit is made to take abuse and keep delivering.
Compared to anything else on the market, the COOLERMAX provides a massive margin of cooling reserve, so you’re not just “good enough”—you’re bulletproof.
Standard and Powerstroke-Specific Options
The DIESELSITE 17-Row COOLERMAX is built to fit your truck and your preferences. Buyers can choose cooler fittings only for a simple upgrade or opt for a complete installation kit that includes hoses, clamps, and hardware for a hassle-free setup. Both options are available with 3/8″ or 1/2″ fittings to match your truck’s lines. For enthusiasts running the popular 1994–2003 Ford Powerstroke, there’s a dedicated kit designed for a direct-fit, bolt-on installation, providing heavy-duty cooling for these legendary 7.3L and early 6.0L trucks right out of the box.
Versatility in Installation
Mount it up, down, or sideways. Run it standalone or in series with your OEM cooler. The COOLERMAX plays well with just about any setup, giving you unmatched flexibility.
Your cost? A fraction of what a transmission rebuild will run you.
