You should consider this upgrade:
Steering shafts upgrade
It adds a Borgeson Vibration Reducer. It won't help the 60mph steering shake that a lot of us have, but it's worth it in steering feel. My #272 did not need the Heim joint support because the the steering column is longer than Spdbrake's (yours probably is too).
If you do it, buy the stainless version of DD shaft (Borgeson 419422 - Stainless Steering Shaft - 3/4"-DD x 22" Long) (I only used around 13") and paint the couplers and vibration reducer before you install or they will rust. This, and the KYB KG5529 rear shocks, are the best (and cheapest) upgrades I've done so far. Oh, and change the steering column bearings while you've got it apart (
