TeraFlex Jeep JK Wrangler 1.5 in. Spring Leveling Kits

TeraFlex Jeep JK Wrangler 1.5 in. spring leveling kits cure the factory nose-down rake of your JK Wrangler or JKU Wrangler Unlimited. Although called leveling kits, they raise the front and the rear, as well as clearing up to 33 in. tires. These TeraFlex leveling kits are ideal for mild trails due to the increased ground clearance and the ability to fit larger diameter tires. They improve approach, breakover, and departure angles. Though rocker and skid plates can help protect the body and drivetrain, these kits may not be high enough to avoid dragging, or even getting hung up, on tall objects. Additional features and benefits of TeraFlex Jeep JK Wrangler 1.5 in. spring leveling kits include: * Longer coil springs increase suspension travel * Additional spring rate prevents sagging from heavy aftermarket bumpers, winches, and cargo racks * Work with the stock-length shocks * Kits include 2 in. lift front coil springs and 1 in. lift rear coil springs, longer front sway bar links, and all necessary hardware

QA1 Bolt-On Subframe Connectors

The 1967-69 F-body was designed in an era when high performance driving and modern tire technology weren't as prevalent. Their unibody chassis, while innovative at the time, can flex and twist under stress, particularly when cornering aggressively or accelerating hard. QA1's bolt-on subframe connectors offer a simple and effective solution to this common issue. They tackle the flex issue by increasing frame rigidity, leading to a significant improvement in handling performance—especially during cornering, acceleration, and braking. The tubular design connects the front Camaro/Firebird subframe to the rear subframe, providing additional structural support and stiffness to the chassis. Additional details: * Included solid body mounts and hardware further reduce chassis flex. Their aluminum construction offers a noise-free alternative to polyurethane. * Thoughtful design: The QA1 subframe connector contours to follow the body lines for a factory-like look without sacrificing ground clearance. * Easy bolt-in installation makes the upgrade hassle-free. * Fitment notes: Does not fit convertibles.
