Walker Evans Certified Kesterke Shock
Every generation pushes harder, rides further, and demands more — eventually the equipment has to catch up. Instead of tweaking what already existed, we built what comes next. The Walker Evans Certified Kesterke Shock is the result of Caleb Kesterke teaming up with Polaris to develop a shock calibrated for how riders and sleds have actually progressed.
The Most Capable Aftermarket Shock, Period
This isn't an incremental update — it's a shock designed from the ground up for modern riding. Bigger reservoir. Larger shaft. Full high-speed, low-speed, and rebound adjustability. Whether you're riding deep backcountry powder or lining up for race day, this shock gives you the range to dial in exactly what you need.
What Sets Them Apart
The Kesterke Shock's baseline calibration is built for the modern off-trail, backcountry riding style: hop-overs, bow ties, side-hilling through trees, pushing into gnarly zones, and riding pillows. That means you use the majority of the shock's stroke in normal winter conditions, not just when you're pushing to the limit.
Dial It In, In Minutes
From full mountain setup to full race spec and back to jump-ready — riders are switching configurations in minutes. Whether you're an advanced mountain rider or an intermediate/beginner rider who wants a plush, forgiving setup, these shocks scale to your skill level and riding style.
Every set ships with a setup sheet and recommended settings — soft, medium, or firm — so you're never guessing where to start.
"You know for me I have a very extensive racing background, competetive background at X-Games, and being able to really dial the shock in for what I need in that moment, I think this is really going to nail that. I was able to generate track speed and ski lift at the same time which you know out in big mountain terrain is pretty crucial. I could get the sled into a traction point and just kind of sit there and hold it there and keep the gas on and the suspension was actually doing a lot of the work to give me enough ski lift, but also be able to continue moving forward without worrying about flipping over backwards."

"I have ran other shocks that had good valving and they wouldn't bottom out, but they were too progressive on the bottom part of the shock stroke, so i had to ride the sled really hard to even get the shock to work properly. These are calibrated in a way that riding deep snow like this in normal winter conditions, I actually use the majority of the shock stroke and I get to push the shock to it's full capability, giving me a better riding experience. I'm really excited for this shock because I think it's going to transform people's riding experience. They're going to be able to progress faster, ride longer with less fatigue, and have better days on the mountain."

"The adjustability is crazy. We went from full on mountain riding, I was testing that setup for multiple weeks, to full on race spec that got me my best results that I've ever had in that race. Then the very next day, I stiffened it back up, put some more preload in it, and was able to go hit some jumps. So just within a couple minutes you can have whatever you want with these things. Being that I am a skilled mountain rider I can benefit a lot, but we can set these shocks up super soft for intermediate to beginner level riders and I think everyone can benefit from these shocks. They're an all around perfect package."
