The SX2-4034 is the most produced size of tandem axle units, with a 204″ wheelbase tractor you can achieve 80,000 legal gross in all states under the Federal Bridge Formula. For shorter wheelbase tractors the SX2-4236 is a common size. Shorter tandems are also produced for maneuvering issues or combined with converter dollies for doubles operations. Common lengths for shorter tandems are SX2-3024 and SX2-3327.
