Ready Air FORD F150 09-14 LOAD LEV 88-21090

The Ready Air LOGIQ Air Spring Kit (SKU 88-21090) is a purpose-built load leveling air spring kit for the 2009–2014 Ford F-150, engineered to restore ride height, improve stability, and support heavy towing and hauling loads. Using the latest air spring technology, this 100% factory-assembled kit ships ready to install — no fabrication, no drilling required — making it one of the most straightforward rear suspension upgrades available for your F-150.

Key Features & Benefits

• Factory-Assembled, Ready-to-Install Package: The kit arrives 100% pre-assembled, dramatically cutting installation time compared to traditional air bag setups. Simple clamp-around bracket designs mean no drilling is required.
• Durable Single Air Sleeve Configuration: Mounts on top of your factory leaf springs with a single air sleeve per side, providing robust load support while keeping the installation straightforward and reliable.
• Optimized Ride Quality at 1.6 Hz Natural Frequency: LOGIQ air springs are engineered to a 1.6 Hz natural frequency — significantly softer than competitor double-bellow designs that typically operate near 2.5 Hz (close to race-car stiffness). The result is a noticeably smoother ride whether you're loaded or empty.
• Up to 3,200 lbs Load Capacity @ 150 psi: With a maximum operating pressure of 150 psi and a minimum of 5 psi, the kit provides substantial rear load support for towing trailers, hauling payload, or running accessories that add weight over the rear axle.
• Retains Factory Bump Stops & Maximizes Suspension Travel: Unlike competing systems that eliminate OEM bump stops and limit travel, this kit is designed to maintain factory bumpstop integration and deliver improved suspension travel — keeping your F-150's suspension geometry working as intended.
• Precision Fitment via Factory Frame & Leaf Spring Location Points: Built-in locating features reference the factory frame and leaf spring positions, ensuring correct geometry and operation on every install without guesswork.
• Properly Scaled to Your Truck: Rather than a one-size-fits-all approach, LOGIQ sizes the air spring to the specific truck platform, genuinely maximizing towing and hauling performance for the F-150 application.
• Lifetime Warranty + ReadyGUARD Powertrain Coverage: All LOGIQ suspension kits include a Limited Lifetime Warranty and a complimentary ReadyGUARD 5-year / 60,000-mile Powertrain Warranty — serious peace of mind for a working truck.
• Upgradeable Air Management: The base kit includes a Manual Inflation Kit with airline and Schrader valves. You can upgrade to LOGIQ's AirIQ SD1, SD2, or HD2 compressor-based management systems at the time of purchase for on-the-fly pressure control.

Frequently Asked Questions

Q: Does this kit require drilling into the frame?
A: No. The LOGIQ Air Spring Kit uses simple clamp-around bracket designs that locate off factory frame and leaf spring positions. No drilling is required, which is one of the primary reasons installation time is significantly reduced compared to traditional air bag kits.

Q: Will this kit work with my F-150 Raptor or if I have aftermarket leaf springs installed?
A: No — the 88-21090 is not compatible with the F-150 Raptor trim package, and it is also not compatible with most aftermarket leaf springs. It is engineered specifically for the factory leaf spring setup on 2009–2014 standard F-150 models.

Q: Can I upgrade to a compressor-based air management system instead of manually inflating through Schrader valves?
A: Yes. LOGIQ offers several AirIQ management system upgrades (SD1, SD2, HD2) that pair with this kit for on-the-fly pressure adjustment. These are available as add-on selections at the time of purchase.

Q: What warranty comes with this kit?
A: LOGIQ Air Spring Kits include a Limited Lifetime Warranty on the suspension components, plus a complimentary ReadyGUARD 5-year / 60,000-mile Powertrain Warranty — providing comprehensive coverage for a working truck application.
