Fabtech Rear Add-A-Leaf Spring Kit

Fabtech's Rear Add-A-Leaf Kits deliver a proven, bolt-on solution for trucks and SUVs that need more from their rear suspension. Whether you're dealing with rear sag under load, hauling heavy payloads, or towing trailers, these kits are engineered to restore and enhance your vehicle's load-carrying capacity while keeping the factory leaf spring pack intact.

What sets Fabtech's approach apart is their use of modern thin leaf spring technology. Traditional add-a-leaf designs often rely on thick, rigid leaves that dramatically stiffen the ride — Fabtech's engineering philosophy prioritizes balance, delivering meaningful load support without sacrificing everyday ride quality. The result is a suspension upgrade that works with your factory setup rather than against it.

Key Features:

• Modern Thin Leaf Design — Advanced spring geometry provides load support while preserving on-road ride quality
• Increased Rear Load Capacity — Engineered to handle the added stress of towing, hauling, and heavy payloads
• Rear Leveling Performance — Reduces rear squat and helps maintain a level stance when loaded
• OEM Spring Pack Integration — Designed to bolt directly into your factory leaf spring assembly with no permanent modifications
• Straightforward Bolt-On Installation — Purpose-built for efficient installation without requiring extensive disassembly
• Preserved Suspension Compliance — Maintains articulation and ride comfort during everyday unloaded driving
• Fabtech-Engineered Quality — Developed by one of the most respected names in aftermarket suspension

Fabtech has built its reputation over decades of suspension engineering for trucks, SUVs, and off-road vehicles. Their Rear Add-A-Leaf Kits reflect that expertise — each kit in this product line is application-specific and purpose-built to deliver consistent, long-lasting performance. If you need to firm up the rear end, carry more weight with confidence, or simply keep your truck level under load, this line offers a practical, durable upgrade backed by a brand that professionals and enthusiasts trust.
