Product Details

The Mopar Performance P4120074 Rear Spring Mounting Seats provide a reliable solution for installing leaf springs on custom rear axle assemblies. These universal spring perch brackets are designed to fit 3-inch diameter axle housing tubes and feature a 2-1/2 inch perch width to accommodate most leaf spring applications.

Key Features:

  • Heavy-duty stamped steel construction for maximum strength and durability
  • Fits 3-inch diameter axle tubes (compatible with 8-3/4", Dana 60, and similar rear ends)
  • 2-1/2 inch perch width for standard leaf spring applications
  • Spring locator pin hole centerline at 0.625 inches (5/8" alignment hole)
  • Natural steel finish ready for welding installation
  • Sold as a pair for complete axle setup

These spring mounting seats are manufactured from high-tensile, heavy-gauge steel to withstand the stresses of rear suspension loads. Ideal for custom builds, axle swaps, and suspension modifications where factory spring perches need to be replaced or relocated. U-bolts not included—please verify spring locator pin size for proper fitment before installation.
