If you own or have ridden a Polaris Pro RMK or the new AXYS RMK you are all too familiar with the limitations of the OEM Walker Evans shock package. OEM suspensions are tuned for specific riders and cannot feasibly be tuned for every rider in the stock configurations.

Our TRS Spring Packages are designed as DIRECT replacements for the springs on OEM Walker Evans shocks but with significant performance improvements!

The beauty of the one piece TRS spring design is that they are coiled as one continuous piece in our bowling pin styled design. This design is engineered to reduce weight over other springs on the market and increase stability by better controlling buckling of the spring. Our springs eliminate shock body wear caused by mechanical bind seen in conventional multi spring/collar designs and are also whisper quiet.

The Raptor Performance Shocks TRS Springs are designed to soften up the first half of the shock stroke, while increasing the stiffness on the last half of the stroke.

Typical Base Kit Rider Weight: Up to 250lbs.

If you are an aggressive rider and in the 250lbs + weight range, the TRS Firm Spring Kit is better suited for your riding style.

Weight 8 lbs

    Wow, blown away on how these springs have transformed my sled from a stiff bouncy exhausting ride, to a bump eating machine. Its like having a trophy truck through the whoops now. Less fatigue on the road ride and awesome absorption for the big jumps. Highly recommend!!!

    Took out my polaris axyis rmk for it first ride. I thougt my 2012 pro rmk was rough on the whoops the axyis was was brutal.Checked the for some dual or three stage springs and Raptor came up. Callrd Jake and had a chat about the product and had him send me a set. I installedd them and road them for 2 days this weekend. In about 2 minutes down a ungroomed trail upto the alpine I knew that the choice was right. The suspention absorbed the bumps nicley .The performance in the deep powder was excellent the track push I exsprienced also disappeared. Thanks Raptor. It is an upgrade that all sled riders should put first on their ride.

    2022 Polaris Matryx Slash, paired these triple rate springs with my Walker Evans Velocity shocks and it made the sled come alive! The small bump absorption feature also helps the sled roll up on edge in the backcountry. The secondary stability that these springs produce is also a nice benefit! The standard stiffness springs are perfect for me at 1/2 turn tighter than the recommended 10.25″ unweighted preload and I’m about 185-190 lbs with gear. This is my second sled with these springs- the stock sled was great, but these springs just make everything better and add a playfulness that the standard stock springs just didn’t offer.
