What the AI looks for in Automotive Replacement Leaf Spring Leaf Springs

Spring dimensions
Match eye-to-eye length, center bolt position (centered or offset front to rear), spring width and eye type An offset center bolt installed backwards shifts the axle, and wrong eyes will not fit the hangers.
Capacity and leaf count
Match the factory rating and leaf count unless you deliberately want heavy-duty springs A stiffer pack than you need rides harshly when empty and can upset braking balance.
Free arch and ride height
Check whether the spring restores stock height or adds lift Lift springs change driveline angles, shock length and brake proportioning.
Mounting configuration
Confirm spring-over-axle or spring-under-axle, and single or dual eye wrap The same vehicle can use different packs depending on axle and package.
What's included
Check whether bushings, center bolt and U-bolts come with the spring and whether it is sold singly or as a pair Listings often show one spring, and missing hardware delays the job.

Are trailer leaf springs interchangeable with vehicle springs?

No. Trailer springs (slipper or double-eye) are sized and rated for trailer axles and should not be used on vehicles.
