TRQ Rear Shock & Spring Assembly Set (Pair) — Pre-Assembled Heavy-Duty Rear Coilover Replacements

TRQ Rear Shock & Spring Assembly Set delivers two pre-assembled, heavy-duty rear coilover replacements engineered to restore ride height, improve load support, and match original equipment fitment.

This pair of rear shock and spring assemblies from TRQ is a ready-to-install solution for drivers who need a dependable direct-fit replacement. Each kit contains one driver-side and one passenger-side heavy-duty shock with matched coil spring, built to simplify installation and return the rear suspension to proper alignment and ride characteristics. TRQ emphasizes compatibility and DIY support, offering fitment references and a library of installation videos to guide the repair.

How do these assemblies make rear suspension replacement easier?

Each unit ships pre-assembled so you avoid compressing springs or aligning mounts during installation. That reduces labor time, lowers the risk of assembly errors, and removes the need for specialty tools in many cases. These direct-fit pieces are sized to match factory mounting points for a bolt-on replacement experience.

• Pre-assembled shock and spring for faster swap-outs
• Direct-fit design aligns with original mounting points
• Heavy-duty components for improved load handling
• Referencable part numbers (58639; 43180) to confirm match

What performance differences should I expect after installation?

The heavy-duty valving and matched coil springs are built to support vehicle weight and accessories more consistently than worn factory units. Expect more stable rear-end support under load and reduced sag when carrying cargo or towing light loads. While they refresh ride stability, these are replacement assemblies—not performance-tuned aftermarket upgrades.

• Restored ride height and rear-end stability
• Improved load support compared to worn shocks
• Consistent rebound and compression for everyday driving
• Not intended as high-performance racing components
