have a customer with a 2005 2500 duramax, torsion keys twisted all the way up running 33s. idler arm, pitman arm, and tie rods worn and 4 month old axle boots busted. looking for any suggestions on needed steering upgrades and more reliable axle boots. ive read everything cognito, to kryptonite, to moog upgrades, does it need the beefed up center link or idler arm bracing? he used cheap axles last time so looking for something that will last longer with a fairly harsh cv angle. He has stock trans efi live tunes, 35 mud grapplers, and again a harsh cv angle. He occasionally pulls and hits the strip but it is mainly a trailer hauler weekend rider. We understand that nothing will bulletproof without a diff drop but just looking for the BEST option for the way the truck is set up now. Thanks INLINE WRENCHER
