When your rear suspension starts feeling saggy or your ride bottoms out over rough terrain, you face a common decision: replace the whole shock assembly or just the worn parts. The SPI Rear Suspension Gas Shock Assembly SU-04323 takes a middle path. At $135.45, it's an aftermarket rear shock that focuses on the shock assembly itself rather than a complete spring-and-collar package.
Quick verdict: The SPI SU-04323 is a new, gas-charged rear shock assembly with a performance/aftermarket classification. It's not a full suspension kit, though, so the rest of your setup matters.
Who it suits: This shock is for riders who plan to keep their existing OEM bushings, springs, and collars. If those components are within spec, the SU-04323 gives you a replacement path without needing a complete suspension overhaul. It's also a good fit if you want a new part with clear identifiers like the MPN and UPC for easier parts matching. If you're already planning to service the rear of your vehicle, this part keeps the project focused on the shock itself.
What stands out: The shock design, the new condition, and the Performance/Aftermarket label position this as a direct replacement part. The MPN SU-04323 and UPC 191361370229 give you concrete part numbers to reference. It ships from the USA with a one-business-day handling time.
Meaningful trade-offs: The biggest trade-off is hardware reuse. Because the shock is designed to work with OEM bushings, springs, and collars, you'll need to keep those components from your current setup. If any of them are worn, factor in replacement costs. Also, confirm the SU-04323 matches your specific make and model before ordering.
SPI Rear Suspension Gas Shock Assembly SU-04323
At $135.45, this new rear shock assembly is priced as a standalone component rather than a complete suspension package. The reason to choose it is the performance-oriented shock design. One limitation to keep in mind: the product image is for reference only, so the actual shock may vary slightly from the photo.
Bottom line: The SPI SU-04323 is a reasonable choice for a rider who wants a new rear shock and is willing to reuse existing suspension hardware. For the right setup, it's a sensible replacement. Just go in knowing that the shock is only part of the equation.
