Frequently when installing aftermarket or upgraded tracks and/or suspension components it becomes necessary to trim the front of the slide rails for clearance. Usually this is done to facilitate installing ex-volute anti-ratchet drivers. When the front protective plastic guides are removed they must be replaced with something to prevent the rails from piercing the track (stabbing). Usually due to the high amount of friction at this location wheels are added to prevent rubbing and track stabbing. Currently on the market there are several companies that build similar products, but as mountain sleds have evolved the current designs have not. Most use small wheels, shafts and bolts that are prone to breakage, causing the exact damage they were installed to prevent. Our Bulletproof Anti-Stab Kit is built strong enough to give customers confidence that it will NEVER fail. Even in high horsepower, boosted applications where the front of the track is subjected to repeated wheelie impacts this product will hold up. Installing ex-volute anti ratchet drivers? The Mountain Tek Performance BULLET PROOF ANTI-STAB KIT will allow you to trim the front of the rails for clearance and keep the rails from piercing the track. Gone are the weak bolts, collars that come loose and snap ring grooves that weaken the already puny shaft found in our competitors products.
