Ok... Since no one here wants to do the leg work..I'll do it..lol I looked up the manual/ parts list for ur truck. I took a look at the servo saver.
It's that week plastic ring like Tamyia used. Heres a thought...it might work..it worked for me on another truck. My Losi Lst 2.
It uses medal bands for the tension on the servo saver ..and for racing to was very week. the trick was to add more metal band..It worked,
great!! U might be able to use those same losi Lst SS bands , and clip them around that plastic stock one on ures. I add 2 extra bands on mine. Good luck hope that helps!!
