OPTI-RATE REPLACEMENT LEAF SPRINGS for 2015+ FORD TRANSIT (PAIR) - Van Compass

Transit Rear Spring Installation Instructions   VIDEO: OPTI-RATE REPLACEMENT LEAF SPRINGS 

Upgrade your 2015+ Ford Transit rear suspension with the Van Compass OPTI-RATE Replacement Leaf Springs, designed to improve ride quality, load support, and suspension control on built-out vans. Unlike conventional leaf springs that require a fixed spring rate and lift height, the OPTI-RATE system allows you to adjust the spring rate and ride height as your van build evolves, making it suitable for everything from lighter builds to heavily loaded camper vans. Compatible with RWD and AWD Transit models, the matched pair uses a progressive spring design with adjustable preload spacers for customizable suspension tuning.

• Tunable spring rate and ride height without replacing the leaf springs
• Progressive design with a primary main spring and three-leaf secondary stage
• Billet-machined Adjustable Preload Spacers (APS) with stackable Delrin glide pads
• Light builds: springs without APS for the softest ride
• Mid-weight builds: APS with 1 Delrin spacer for a firmer spring rate and slight lift
• Heavy builds: APS with 2 Delrin spacers for maximum spring rate and ride height
• Configuration changes require only basic hand tools, a floor jack, and a mallet
