PR Racing is excited to release the new Aluminum Caster Block for the S1 V4 2WD buggy. This 91400039 PR S1 V4 Aluminum 3 Degree Caster Block comes with height adjustment spacers to fine-tune the axle height and roll center. Different ride height settings have proven critical on the wide range of track types racers compete on today, and these caster blocks will allow you to retain the proper suspension geometry whether you run your car lower on high-grip smooth tracks or higher on low-grip bumpier conditions.
