WFLNHB 5" Rear Axle Flip Kit for Chevrolet C10 & GMC 1973-1987 — 5" Rear Drop, Bolt-On Steel Replacement

WFLNHB's 5" rear axle flip kit is a bolt-on replacement that lowers 1973–1987 Chevrolet C10 and equivalent GMC 1/2-ton trucks by five inches at the rear without cutting the axle or converting the suspension type.

For owners restoring, customizing, or lowering classic C10 and GMC trucks, this flip kit offers a straightforward way to achieve a raked stance and improved rear drop while preserving the original leaf-spring suspension layout. Built from solid steel and finished for durability, the assembly replaces the factory axle perch orientation so the axle sits lower relative to the spring. The kit includes the main flip plates, axle locators, U-bolts and hardware needed for a bolt-in installation, making it a cost-effective alternative to swapping to a coil spring rear or purchasing drop-leaf springs.

How does the kit lower my truck without changing springs?

The flip kit repositions the axle under the leaf springs by flipping the axle mount orientation. Instead of replacing springs, the kit moves the axle downward relative to the chassis, creating approximately five inches of rear drop while keeping the original spring pack and ride characteristics.

• Reorients axle perches to reduce ride height about 5" at rear.
• Keeps factory leaf springs and mounting points intact.
• Works as a direct replacement for 1973–1987 Chevy C10/GMC 1/2-ton axles.

What comes in the box and what tools will I need?

The package contains the primary flip plates, axle locators, mounting plates, U-bolts, lock nuts and washers so you have the major components required to secure the axle in its lowered position. Typical installation needs common hand tools, a jack and stands, and basic mechanical experience to align and torque fasteners properly.

• Included: flip plates, axle locators, mounting plates, U-bolts, locknuts, washers.
• Suggested tools: floor jack, jack stands, socket set, torque wrench, basic hand tools.
• Estimated install time: a few hours for experienced installers.

Will this fit my 1973–1987 Chevy C10 or GMC truck?

This kit is intended for 1/2-ton Chevy C10 and GMC trucks from 1973 through 1987; compatibility depends on axle and suspension variations. Verify your axle style and model year before purchasing and compare measurements where possible to ensure correct fitment.

• Designed for Chevy C10/GMC 1/2-ton trucks, 1973–1987 model years.
• Check axle diameter, perch locations, and leaf-spring layout for compatibility.
• Contact the seller or a mechanic if unsure about your truck's specific configuration.

How does this compare to other lowering methods?

Compared with replacing leaf springs or converting to a coil-spring rear, the flip kit is more affordable and less invasive. It preserves original suspension components and can be reversed, though it does alter driveline angles and may require additional adjustments such as re-indexing brake lines, shocks, or driveshafts for optimum geometry.

• Lower cost than new drop leafs or coil-spring conversions.
• Simple bolt-in method versus cutting or major axle modification.
• May need supplemental adjustments (brake line length, shocks, pinion angle).

Who is this for: This WFLNHB 5" rear lowering flip kit is aimed at classic-truck enthusiasts, restorers, and budget-minded modifiers who want a clean lowered rear stance for 1973–1987 Chevy C10 and GMC 1/2-ton trucks without replacing the leaf-spring system. Installers with basic mechanical skills or professional shops looking for a reversible, robust steel solution will find this kit a practical option. Always confirm vehicle compatibility and consider associated suspension and driveline tweaks to maintain safe handling and alignment after installation.
