When the suspension on your 2011 Ski-Doo Renegade Backcountry 800R Power TEK starts to feel less composed, the spring can be responsible for a lot of the play and sag. The challenge is finding a replacement that is tied to your exact snowmobile rather than a generic part. This SPI spring appears to be that kind of direct application part, and the listed price puts it in an easy-to-evaluate range.
Quick Verdict
If you need a new suspension spring for this specific Renegade Backcountry model, the SPI spring at USD 47.95 checks the basic boxes. It's a new part, it carries a manufacturer part number (5201-S482243-71), and it's specifically named for the 2011 Ski-Doo Renegade Backcountry 800R Power TEK. That makes it a strong candidate to order if you're replacing a spring that's had a hard life.
Who It Suits
This spring is aimed at owners of the 2011 Ski-Doo Renegade Backcountry 800R Power TEK who want to restore the suspension to a stock-like state. It's a single-spring replacement rather than a multi-piece kit, so it fits the budget of someone who has already diagnosed the issue and just needs the right part.
What Stands Out
The most useful detail here is the part number. Sports Parts Inc has tied the SPI spring to the exact sled, and the manufacturer part number listed is 5201-S482243-71. When you're dealing with snowmobile suspension, that kind of identification makes it easier to match the replacement to your original hardware.
Trade-offs
The emphasis is on fit for the specific Ski-Doo model, so ordering it is straightforward when you need a stock-style spring. The trade-off is that it's not framed as an upgrade part; it's a spring replacement matched to one sled.
Bottom Line
For a 2011 Ski-Doo Renegade Backcountry 800R Power TEK owner who wants a new suspension spring and a clear part number, this SPI spring is a solid buy. The new condition removes the unknown of a used spring, and the specifics are easy to track.
Product Note
SPI Suspension Spring for 2011 Ski-Doo Renegade Backcountry 800R Power TEK

Choosing this spring gives you a new part from Sports Parts Inc at USD 47.95. The part number 5201-S482243-71 is the clearest identifier for matching it to your sled. One limitation to keep in mind is that the listed price reflects a single spring, so if you're restoring a full suspension setup, you'll want to account for each spring you need.
