S3 Powersports HD Springs for Can-Am Defender $222.87 – $422.28 S3 Power Sports Can-Am Defender HD Springs! The S3 Power Sports Can-Am Defender HD Springs are engineered with performance and functionality in mind. These Heavy Duty springs are designed to increase your load capacity and decrease suspension “sag” you get with factory springs. You will also improve vehicle stability with the increased spring rate and, in many cases, increase ground clearance. If you like to work hard or play hard, our Can-Am Defender HD Springs are a necessity. Some other Canadian websites have priced these “PER SPRING”. Be careful if you’re comparing prices that you are not just going by pictures on their website. Extreme Duty (ED) Springs: A “stiffer” alternative to our HD Springs, Extreme Duty Springs are ideal when managing exceptionally heavy loads. NOTE: Some X mr, Cab, & Lone Star Editions include required Front Spring Spacers.
