Transit Opti-Rate Rear Leaf Spring Ford Transit-350 HD/Transit-350/Transit-250/Transit-150 (2015-Up) - Van Compass - 3065

Our Opti-Rate spring pack represents the culmination of over a decade spent tuning leaf springs for various ride heights, payloads, applications and uses. Built out vans often suffer from harsh bottom out due to the constant weight being carried, and will drive very poorly overall.

Previously, leaf springs had to be ordered to a specific weight range and lift height, which meant either guessing or waiting until completion to order parts. The Opti-Rate spring gives new flexibility in tuning both your spring rate and ride height, all in one package.

With an industry first tunable preload system, we've developed a spring that truly is a 'one size fits all' solution, perfect for van builders, kit installers, and Diy'ers building their vans step by step on their own. The Opti-Rate spring is made up of 3 distinct parts: the main springs in the primary stage, a 3-leaf secondary stage, and the Adjustable Preload Spacers (Aps).

The Adjustable Preload Spacers are machined blocks with stackable Delrin glide pads that preload the secondary stage into the main stage. The springs are designed in a way that there is a gap between the 2 stages, perfect for adding our billet machined Aps.

When the main spring is weighted, the Aps are able to engage the primary and secondary stages together. Changing the preload spacers requires little more than a floor jack, socket wrench, and a mallet; the springs can stay in the vehicle.

For light vans, or customers wanting the softest ride, no Aps is needed and the spring works in its softest configuration. Middle weight vans, or customers wanting a firmer rear spring rate and increased ride height can add the Aps with 1 Delrin spacer pad.

Heavy vans, or customers wanting the maximum spring rate and ride height can install the Aps with 2 Delrin spacer pads.
