What's wrong?
The rear leaf spring spacer block on the 2015 Pierce Impel, Enforcer, Saber, and Velocity sits in the rear suspension at the leaf spring assembly. Its job is to hold the rear axle and spring stack at the correct spacing so the suspension carries the vehicle's weight evenly while the axle moves over the road.
On affected vehicles, that spacer block was made from cast iron after a design change. Pierce found that cast iron was the wrong material for this application. Cracks formed in the block during vehicle builds, and a cracked block can fracture. A separated piece can come off the vehicle instead of staying captured in the suspension.
The warning sign is visual, not something the driver feels first. A crack is visible when the part is inspected, but there is no warning sign to the driver or people nearby before a piece separates.
Who's affected?
The scope spans Impel, Enforcer, Saber, and Velocity fire apparatus, all with the same rear suspension leaf spring assembly.

What should I do?
- Check your VIN to confirm your 2015 Pierce Impel, Enforcer, Saber, or Velocity is included in this recall.
- Do not drive the vehicle until the rear leaf-spring spacer block repair is complete.
- Arrange a tow if the vehicle has to be moved to the dealer; do not drive it there yourself.
- Contact a franchised Pierce dealer to schedule the free replacement of the rear leaf-spring spacer block so a cracked block does not drop pieces onto the road or shift rear axle alignment.
- Bring the recall notice if Pierce has mailed one. If not, reference recall number 15V174 when you call.
What happens at the repair
At the dealer, a Pierce technician replaces the rear axle cast iron leaf spring spacer block with a machined steel spacer block. That part sits in the leaf spring stack and helps keep the rear axle suspension properly spaced under load. The recall repair is free, including parts and labor. Ask the service desk to confirm that campaign 15V174 is open for your VIN before the vehicle goes into the bay.
