This latest design creates a huge&nbsp;improvement in&nbsp;engine braking&nbsp;compared to our dual roller tuner. All billet construction capable of using compression springs with different spring rate options. We have&nbsp;many&nbsp;helix angles-see&nbsp;menu&nbsp;above. We can also provide custom helix angles if you desire for an additional fee.<\/span><\/p> <p><span>We also offer the option of an encapsulated helix design that keeps the driven from unloading, opening and going into high gear during breaking and jumping which some racers require.<\/span><\/p> <p><span>Can be used along with the stock primary or the STM primary. Best results are acquired when running both the STM primary and STM tuner together.&nbsp;<\/span><\/p> <p><em><span><strong><span><span>When ordering use this guide to help you pick options &nbsp; &nbsp;<\/span><\/span><\/strong><\/span><\/em><\/p> <p><em><span><strong><span><span>Number of shims<\/span><\/span><\/strong><\/span><\/em><span class=\"apple-converted-space\">&nbsp;<\/span><span>&ndash; The amount of shims we install will determine your belt deflection or how tight the belt will be between your primary and driven clutch. Keep in mind we are setting the deflection for a stock belt, for an RZR pre-2010 choose 1 shim, RZR 2011-2015 choose 3 shims, XP choose 3 shims. Keep in mind the more shims you add the looser the belt-less shims tighter belt. NOTE: You want to have your belt as tight as possible without the bike creeping forward while in gear at idle.<\/span><\/p> <p><em><span><strong><span><span>Choose a helix angle<\/span><\/span><\/strong><\/span><\/em><span class=\"apple-converted-space\">&nbsp;<\/span><span>&#8211; The most popular helix is the 45&deg;.
