Perfect for C10 & GMC Truck Owners Looking for a True 5-Inch Rear Drop

The 1967–1972 GM truck platform (commonly called the “Action Line” generation) is one of the most popular and customizable classic truck chassis in the world. They’re known for timeless styling, rugged drivetrains, and exceptional aftermarket support—and one of the most common upgrades is suspension lowering to achieve the aggressive stance C10 fans love.

This 5-inch rear leaf spring flip kit helps you achieve:

• A lower center of gravity for improved handling

• A clean, level, and dramatically lower stance

• Clearance for larger wheels and modern tire fitments

• Better alignment of body lines when paired with front lowering springs or spindles

• Reduced fender gap for a custom show-truck appearance

• A more comfortable ride when paired with proper shocks

Whether you’re going for a classic hot rod look, a mild drop for daily driving, or a full custom setup, this kit provides the ideal foundation.

Engineered for Strength, Safety & Long-Term Durability

A rear axle flip changes the entire axle-to-leaf relationship, which means your hardware MUST be strong, properly designed, and properly sized. Every component in this kit is crafted with structural integrity as the priority.

Heavy-Duty 5/8" U-Bolts & Hardware

Unlike universal kits or weaker aftermarket options, this flip kit includes 4 heavy-duty 5/8" U-bolts designed specifically for GM trucks. Oversized fasteners provide superior clamping force, resisting axle wrap, twisting, and harsh load impacts.

All hardware includes:

• High-strength 5/8” x 18 nuts

• Hardened flat washers

• Nylock locking nuts for long-term vibration resistance

This ensures everything stays tight and secure, even under heavy loads or aggressive driving.

Precision Axle Locators for OEM Fit & Alignment

The Axle Locators (1010-A) and Upper Axle Plates (1010-P) are machined to correctly position the rear axle, maintaining proper pinion angle and driveline geometry. This prevents:

• Driveshaft vibration

• Premature u-joint wear

• Axle wander

• Spring misalignment

Correct alignment means your truck drives straight, smooth, and predictable—even after a full 5-inch rear drop.

5-Hole Leaf Spring Plates for Multiple Setup Options

The Leaf Spring Plates (1025) incorporate a universal 5-hole design that works with your 2.25-inch GM leaf springs while giving builders multiple mounting options—ideal for:

• Load handling adjustments

• Aftermarket shock configurations

• Realignment of rear hardware

• Accommodating traction bars or helper springs

The flexibility helps builders dial in the perfect setup whether your truck is a cruiser, tow rig, drag truck, or weekend showpiece.

Flat Bump Stops Included

When lowering a leaf spring truck, bump stop clearance becomes a concern. This flip kit includes (2) Flat Bump Stops (10S) engineered to maintain safety and protect your axle housing and frame rails.

They prevent:

• Hard frame contact

• Axle tube denting

• Abrupt bottom-outs that can damage shocks or leaf springs

These bump stops help maintain proper ride quality and structural protection even after the drop.

Why Choose a Rear Axle Flip Kit Instead of Lowering Blocks?

Lowering blocks simply space the axle downward. An axle flip repositions it above the springs, which creates a cleaner, stronger, and more factory-like solution.

Benefits of an Axle Flip Kit:

• Achieves a larger drop without extreme block heights
• Improves handling by reducing leverage on suspension
• Stronger, safer, and more stable under acceleration
• Eliminates wheel hop associated with large lowering blocks
• Provides more room for suspension tuning
• Creates a cleaner, more professional install

If you're looking for a reliable 5-inch drop without compromising strength or ride quality, an axle flip kit is absolutely the superior method.

Installation Notes & Recommendations

This flip kit installs using normal hand tools and basic shop equipment. Most DIY builders complete the job in 3–5 hours, though professional shops can complete it even faster.

Recommended Tools:

• Floor jack & jack stands

• Torque wrench

• Impact gun or breaker bar

• Grinder or cutoff wheel (to remove old u-bolts)

• Penetrating oil

• Measuring tape or laser alignment tool

Recommended Additional Upgrades:

To complete your lowering system, consider pairing this kit with:

• Drop shocks (shorter travel for lowered geometry)

• C-notch kit, especially for aggressive driving or heavy loads

• Front lowering springs or drop spindles to match ride height

• New trailing arm bushings or panhard bar

• Shock relocation brackets if running aftermarket shocks

These upgrades ensure your truck maintains excellent ride quality and proper frame clearance after the drop.
