Rear Parabolic Leaf Spring, EFS (+50 mm at 450 kg) (+75 mm at 400 kg), Toyota Land Cruiser 2007 - Present

EFS LEAF SPRINGS: MULTI-LEAF vs. PARABOLIC EFS MULTI-LEAF SPRINGS The multi-leaf spring is the choice for maximum strength and reliability . They are manufactured with a stack of constant-thickness SUP9 Japanese steel leaves. Their design is optimized for vehicles carrying constant or heavy loads that require superior lateral stability. Load Capacity : Designed to support heavy weights without sagging, maintaining vehicle ride height. Control : They offer firm and predictable handling, ideal for towing or vehicles with heavy additional equipment. Durability : Their robust structure makes them ideal for the most severe working conditions and intensive use. EFS PARABOLIC LEAF SPRINGS The parabolic leaf spring represents the technological evolution in comfort . Unlike traditional ones, it consists of fewer leaves with tapered thickness (thicker in the center and thinner at the ends). This design eliminates inter-leaf friction, allowing the spring to work much more elastically. Ride Comfort : They provide a much smoother drive, similar to a coil spring, better absorbing road irregularities. Off-Road Articulation : By reducing internal friction, the spring flexes more freely, improving suspension travel and ground contact. Lightweight : They reduce the vehicle's unsprung weight, improving the agility and response time of the suspension system.
