Control arms are the load-bearing connections between your vehicle’s chassis and its wheels. They control wheel position, manage suspension geometry, and absorb the forces that travel through the chassis during acceleration, braking, and cornering. When you upgrade to upper tubular control arms, you’re replacing the factory stamped-steel or composite arms with precision-engineered tubular steel or…
Rod end bearings are critical components in countless mechanical systems, from automotive steering and suspension to aircraft control systems and industrial machinery. Understanding how rod end bearings are made provides valuable insight into why these components must be manufactured to such precise tolerances and why quality matters so profoundly in their function. The question “how…
Wheel spacers are one of the most impactful modifications you can make to your vehicle’s appearance and performance. Installing wheel spacers pushes your wheels outward, widening the vehicle’s track width and giving it a more aggressive stance. Beyond aesthetics, properly installed wheel spacers can improve handling stability and provide clearance for larger brake calipers. However,…
If you’ve spent any time around performance vehicles, racing, or off-road trucks, you’ve probably heard the term “spool” mentioned when discussing rear ends. The phrase “throwing a spool in the rear end” conjures images of track cars, drag racers, and serious performance builds. But what exactly is a spool for a rear end, and why…
Hood pins serve a specific purpose in automotive applications. Whether you’re building a race car that needs rapid access, installing a secondary latch for a street rod, equipping an off-road rig that demands reliable hood security, or simply adding a performance aesthetic to your daily driver, hood pins offer a straightforward mechanical solution that works…
Steering wheel shake while driving represents one of the most concerning vehicle symptoms that drivers experience. Unlike simple noise complaints or minor annoyances, steering wheel vibration directly affects vehicle control and driver confidence. The shaking sensation transmits through one of the most critical interface points between vehicle and driver—the steering wheel itself—making immediate attention essential…
Clevis rod ends are mechanical components designed to provide articulated connections between rods, linkages, and structural members. These components feature a clevis or fork design at one end that connects to a mating component using a pin, while the opposite end typically threads onto a rod or connects to a mounting point. The fundamental purpose…
Lowering blocks serve as suspension modification components that reduce vehicle ride height by installing between the vehicle’s leaf spring pack and rear axle housing. These precision-machined blocks effectively lower the rear of the vehicle when installed in the leaf spring eye or center pin location, creating a more aggressive stance and improved handling characteristics. The…
A hex jam nut is a thin-profile hex-shaped nut designed to be used in conjunction with a standard nut or against a shoulder surface to lock threaded fasteners in position. The term “hex” refers to its six-sided shape, which allows installation and removal using standard wrenches, while “jam” describes its function of being jammed or…
A jam nut is a low-profile fastener with reduced thickness compared to standard hex nuts, typically manufactured at approximately half the height of conventional nuts. The term “jam” refers to the nut’s primary function of being jammed or locked against another nut, component surface, or threaded shaft to prevent loosening and maintain assembly integrity. Jam…
