For all you classic Mustang enthusiasts out there, if you’re wrestling with manual steering in your 1968-1970 Ford Mustang, it’s time to make a serious upgrade. The Borgeson Mustang P/S Kit is here to save your arms and enhance your driving experience. This power steering conversion kit is a game-changer for those who crave better steering ease, responsiveness, and overall driving comfort. Buckle up as we dive into the killer features, crucial components, and the unbeatable benefits this kit brings.

Pump It Up
Small-block water pumps are common replacement parts and are available at prices that are nearly impossible to beat. However, while getting a brand-new water pump for cheap is great, sometimes you need to keep the one you have. If it’s date-coded, or maybe you’ve installed a chrome steel or an aluminum water pump. You aren’t going to get those at the parts counter. In cases like these, rebuilding a water pump is preferred to buying a new one.

TWO WORLDS CONVERGE
Nick Barron is no stranger to building fine performance vehicles. For more than 40 years, he has been the catalyst in handcrafting some of the finest performance machines around, a clockwork of components powered by nasty big-block Chevy engines and outfitted with the finest in custom appointments. The results of his handiwork have been seen racing on the quarter-mile and in other tortuous events. His vehicles have received many recognized awards for product innovation and consumer excellence. With a reputation for quality workmanship, performance, speed and superior handling, the success of Hallett Boats can be attributed directly to Barron. The boats Hallett has produced over the last four decades have afforded him the opportunity to involve himself in a number of new, exciting adventures. Barron is not only the owner of this new, beautiful Jerry Kugel-created full-fendered ’32 Muroc II roadster, he is also the owner of and innovator behind Hallett Boats, a high-end custom performance boat manufacturer located in Southern California.

Product Spotlight: Posies SuperSlide Springs
A Better Ride Without Giving Up the Classic Look

Let’s face it—old leaf springs don’t always deliver the smoothest ride. Between years of wear and the natural friction created as steel leaves slide against one another, it’s no surprise that many traditional hot rods and classic trucks can feel a little rough around the edges.
That’s exactly the problem Posies SuperSlide Springs were designed to solve.
Instead of simply building another replacement leaf spring, Posies re-engineered the traditional multi-leaf design to provide a smoother ride, better handling, and improved suspension response—all while keeping the vintage appearance that belongs under a classic hot rod or truck.
The Secret Is in the Slide
What sets SuperSlide Springs apart is Posies’ patented design that places durable moly-nylon buttons between each leaf in the spring pack. Rather than allowing steel leaves to grind against one another, these low-friction pads let the springs move much more freely as the suspension cycles.
The difference is something you can actually feel behind the wheel.
The ride is smoother over bumps, suspension movement is more responsive, and those familiar squeaks and groans that come with old leaf springs are greatly reduced. The springs also resist binding, giving the suspension a more consistent feel whether you’re cruising the highway or carving through a winding back road.
Built for Real Hot Rods
Posies doesn’t cut corners when it comes to construction. Every SuperSlide Spring is built in the USA using premium tempered spring steel, heat-treated components, and carefully assembled leaf packs designed for years of dependable performance.
These aren’t parts built just to look good sitting at a car show. Posies says its SuperSlide Springs have been proven on vehicles with well over 100,000 road miles, making them just as comfortable on long-distance road trips as they are parked on the show field.
Built for Your Stance
Whether you’re after a subtle drop or an aggressive hot rod rake, there’s a SuperSlide Spring designed for the job.
The popular Reverse Eye version lowers the vehicle while maintaining excellent suspension travel, while the Low Reverse Eye option drops it about another inch for an even more aggressive stance. Builders wanting to stay close to factory ride height can choose Stock Eye springs, and heavier vehicles equipped with big-blocks, Hemis, or superchargers are covered with Heavy Rate versions engineered to handle the extra weight.
Applications for Some of the Most Popular Classics
SuperSlide Springs are available for a wide range of traditional hot rods and trucks, including:
- 1928–34 Ford hot rods
- 1935–48 Ford cars
- Early Ford pickups
- 1953–56 Ford F-100 pickups
- Chevrolet applications
- Mopar applications
- Rear leaf spring conversions
One popular example is the rear spring kit for 1955–56 Ford F-100 pickups, which lowers the truck about three inches while using the factory frame mounting locations and comes with bushings already installed.
Why They’ve Earned Their Reputation
Ask around at just about any hot rod event, and there’s a good chance you’ll find someone running Posies SuperSlide Springs. They’ve built a loyal following because they solve one of the biggest complaints about traditional leaf-spring suspensions without changing what makes these cars special.
You still get the timeless look of a multi-leaf spring setup, but with noticeably better ride quality, more predictable handling, and a suspension that feels far more refined than you’d expect from a design that’s been around for generations.
If you’re building a Deuce roadster, a Model A, a classic street rod, or a lowered F-100, SuperSlide Springs are one of those upgrades you’ll appreciate every time you hit the road. Sometimes the best modifications aren’t the ones everyone notices—they’re the ones you feel every mile behind the wheel.
