SLP – Built for Riders Who Want More Power, More Control & More Mountain

Starting Line Products (SLP) has been pushing snowmobile performance forward since 1973. Born in Idaho Falls and tested in some of the harshest mountain terrain in North America, SLP builds real performance parts for riders who refuse to settle for stock. If you want harder pull, cleaner throttle response, quicker backshift and more precise handling in the steep-and-deep — SLP is the upgrade.

At West Coast Sledders, we carry a full lineup of SLP performance products designed to make your sled hit harder, climb higher and stay consistent in technical terrain. From power-building exhaust systems to razor-sharp skis and clutching that reacts instantly when you crack the throttle — SLP gives you the edge when the mountain gets real.

Why Hardcore Riders Choose SLP

  • Max Power Gains – Exhausts engineered for real horsepower, not just sound.
  • Dialed Clutching – Instant engagement, smoother revs, and spot-on RPM control at altitude.
  • Laser-Precise Skis – Better lift in deep snow, stronger hold on off-camber climbs, and no more unpredictable darting.
  • Stability in the Gnarly Stuff – Suspension and handling upgrades that keep your sled planted when it matters.
  • Race-Proven Reliability – Tested by real mountain athletes, racers, and backcountry chargers who ride hard every day.

SLP Performance Categories

  • SLP Exhaust Systems – Lighter, louder (in all the right ways), and built for massive mid-range power.
  • SLP Clutch Kits & Components – Springs, helixes, weights and full kits tuned for deep-snow acceleration.
  • SLP Snowmobile Skis – More control, more stability, more confidence in steep, technical terrain.
  • SLP Suspension & Handling – Upgrades that keep your sled predictable when you’re sidehilling through chaos.
  • SLP Intake & Venting – Cooler temps, cleaner airflow, and stronger consistency at altitude.

If you’re riding big mountains, tight trees, cliff bands or deep pow zones — stock isn’t enough. SLP unlocks your sled’s full potential so you can ride harder, deeper and faster with total confidence.

Optimized for BC, Alberta & Big-Mountain Riding

West Coast Sledders carries SLP upgrades for Polaris, Ski-Doo, Lynx, Arctic Cat and Yamaha. Whether you ride Revy, Whistler, Sicamous, Valemount, McBride or the local zone — we’ll help you build a sled that hits exactly the way you want it to.

SLP Performance FAQ

How much performance will an SLP exhaust add?

Most SLP exhaust systems deliver noticeable horsepower gains and major weight savings. You’ll feel stronger pull in the mid-range, cleaner throttle response, and more consistent performance at elevation.

Is SLP clutching worth it for mountain riding?

100%. SLP clutching gives you instant bite when you stab the throttle, smoother backshift on climbs, better belt life and more predictable RPM control in deep snow. It’s one of the best upgrades you can make.

What makes SLP skis better for aggressive riding?

SLP skis offer insane stability and precise steering. Whether you’re threading trees or dropping into steep lines, they reduce unpredictable darting and give you stronger edge hold and flotation.

Do I need suspension upgrades with SLP performance parts?

If you ride fast, heavy or technical terrain, yes. SLP suspension components tighten your sled’s handling, reduce body roll, and help maintain traction in nasty conditions. It’s a game changer for technical riders.

Are SLP parts easy to install?

Exhaust and intake kits are straightforward. Clutching may require tuning knowledge, but anyone mechanically inclined can install SLP parts. If you need help, West Coast Sledders can point you toward trusted installers.

Do you ship SLP products across Canada and the U.S.?

Yes. We ship SLP performance parts across Canada—BC, Alberta, Saskatchewan—and to select U.S. regions. Shipping options vary by location and product size.
