Product Notes
SPI Suspension Spring for 2011 Ski-Doo Renegade Backcountry 800R Power TEK

This spring is for the 2011 Ski-Doo Renegade Backcountry 800R Power TEK. The reason to choose this one is simple: the product name points directly to the Backcountry model you own, and that direct match removes guesswork when you're comparing two similar springs. If that's the sled you're working on, this spring is the obvious starting point. The limitation is that the product name doesn't call out a rear right position, so if you need the SP 800R rear right spring, this one doesn't carry that label. Match the model name on the product to your specific Renegade before deciding.
SPI Suspension Spring for 2011 Ski-Doo Renegade SP 800R Power TEK [Rear Right

For the Renegade SP 800R Power TEK, this SPI spring is labeled for the rear right position. The rear right designation makes it easy to identify which corner it's meant for, which is exactly the reason to pick it when your machine is the SP model. The limitation is that the product name is tied specifically to the SP model, so if your snowmobile is the Backcountry 800R Power TEK, this spring isn't the one for that sled. The model name is the clearest way to keep the two straight.
Final Choice by Use Case
The decision comes down to your specific Renegade. If the sled is a 2011 Ski-Doo Renegade Backcountry 800R Power TEK, the Backcountry spring is the one to choose. If the machine is the Renegade SP 800R Power TEK, the SP spring is the right pick. Match the model name on the product to the sled you're working on, and the choice becomes clear. There's no reason to let two similar-looking springs confuse the decision; the model name is the clear tie-breaker. If you're not sure which one you need, the product name is the part that tells you exactly which Renegade it was made for.
