Under cover coverage
We stock engine under covers and splash shields with correct mounting tabs, integrated grommets, and drain provisions. Configuration by engine and drivetrain confirmed at order time.
When under covers get replaced
Dragging or dangling covers on the ground
A loose cover eventually detaches and gets left behind on the freeway.
Water intrusion causing belt slip
Missing covers let puddles reach the accessory belt.
Post-service that failed to reinstall the cover
Some oil changes skip cover reinstall.

Ordering under covers
Order fasteners together
Under-vehicle fasteners are exposed to salt and rarely reusable.
Confirm drivetrain
AWD and 4WD configurations often require different cover geometry.
Check for oil-drain access ports
Some covers include a drain plug for oil service — confirm before ordering.
