Description
xThe Opti-Rate Replacement Leaf Springs are the result of more than a decade of engineering, testing, and real-world refinement across every type of Transit build—from lightweight adventure vans to fully outfitted expedition rigs. Traditional leaf spring upgrades force owners to choose a specific spring rate or lift height based on estimated final weight, often requiring guesswork or last-minute changes once a build is complete. The Opti-Rate system eliminates that limitation entirely.
Designed as a truly tunable, one-size-fits-all solution, the Opti-Rate spring pack allows you to adjust both spring rate and ride height without removing the springs from the van. Each pack uses a multi-stage approach consisting of a primary main spring, a three-leaf secondary stage, and our industry-first Adjustable Preload Spacer (APS) system, which allows the secondary stage to be progressively engaged based on vehicle weight and performance preference.
Using machined aluminum spacer blocks with stackable Delrin glide pads, the APS system preloads the secondary stage into the primary spring as needed. The result is a customizable suspension solution suitable for everything from empty passenger vans to fully built overland conversions.
-
Light vans benefit from the softest, most compliant ride by running no APS preload.
-
Mid-weight vans can install the APS with a single pad for a firmer rate and increased ride height.
-
Heavy vans or those seeking maximum support can stack two pads for the highest rate and maximum lift.
Adjustments can be made with the springs installed using simple hand tools, making this an ideal system for DIY builders, professional upfitters, or installers working with incomplete or evolving van builds.
Note: Vans equipped with a rear sway bar require extended rear sway bar links (available separately). These leaf springs ship via truck freight; providing a commercial address will reduce shipping costs.
Features
x- Fully Tunable Spring System: Adjust spring rate and ride height using the included Adjustable Preload Spacer (APS) system—no spring removal required.
- Multi-Stage Spring Design: Combines a primary main spring with a three-leaf secondary stage for improved control, load handling, and ride quality.
- Industry-First Adjustable Preload Spacer System: Machined aluminum spacer blocks with stackable Delrin glide pads allow precise tuning for light, mid-weight, or heavy vans.
- Improved Ride Quality: Reduces harsh bottom-outs and improves handling for built-out camper vans or heavily loaded work vans.
- Easy On-Vehicle Adjustment: Spring tuning can be performed using basic hand tools—a jack, socket wrench, and mallet—without removing the springs.
- One-Size-Fits-All Solution: Eliminates the need to guess final vehicle weight or order weight-specific springs during the build process.
- Durable Construction: High-quality materials and engineering provide long-term performance for both AWD and RWD Transit platforms.
- Includes Hardware: Complete kit includes preload spacers, glide pads, and U-bolts with nuts for proper installation.
- Sway Bar Compatibility: Vans equipped with a factory rear sway bar require extended rear sway bar links (sold separately).
