I am running a +5" Lonestar I ordered a +4" but they were out of stock so they gave me a chrome +5" for the same cost. I have had that arm on 2 different Banshees the 1st was a 450cc CT Racing motor running taller haulers. But that quad blew up to many times and all the suspension was transferred on to my daughters 350cc with larger carbs and FMF exhaust. Even with the smaller motor that size seams to work just fine.
