Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model

Product Overview
When a lowered Mustang slams harshly over dips, the rear bump stops may be split, missing, or too worn to cushion the end of suspension travel. These rear jounce bumpers restore the progressive stop that helps keep the axle and suspension from making hard contact.
Ford Performance M-5570-A normally describes a front-and-rear jounce-bumper kit, while this listing identifies rear axle bump stops. Treat M-5570-A as a style/reference check and confirm the pictured quantity, rear mounting design, height, and suspension setup before ordering.

- Two rear suspension jounce bumpers
- Progressive cushioning at the end of axle travel
- Useful with stock or compatible lowered S197 suspension
- Replacement for cracked, compressed, or missing rear stops
- Rear-only package as identified by the listing
Common Uses
- Replacing bump stops that crumble when touched
- Reducing harsh metal-to-metal bottoming
- Finishing a rear shock or spring installation

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, engine or equipment configuration, installed options, and previous repairs can affect fitment. Compare the original part, identifying numbers, dimensions, connections, and mounting details before purchase.
Frequently Asked Questions
Q: Is this the complete Ford Performance M-5570-A kit? A: The listing identifies rear bump stops. The official M-5570-A reference normally includes front and rear pieces, so confirm the exact pictured contents.
Q: Why are jounce bumpers important on a lowered Mustang? A: Lower ride height reduces available travel, making the progressive stop important during large suspension compression.
Q: Can worn bump stops cause a hard bang? A: Yes, but loose shocks, axle contact, exhaust movement, or other suspension faults can sound similar.
Q: Will they raise the ride height? A: No. Jounce bumpers limit and cushion compression; springs establish normal ride height.
