1 | Tamper-proof EPA engine programming | Vehicle Speed Limiter (VSL) and Engine Idle Shutdown Timer (EIST) are Emission Controls that may be noted on the door label. The default VSL speed is 64 MPH and EIST requires 5 minute idle shutdown. The expiration distance for these parameters is between for 300,000 - 1,259,000 miles and CANNOT BE RESET during that period. The expiration is not noted anywhere on the vehicle. You must call Parts and get this number, and use an engine tool to remove the value when applicable, if desired. |
2 | Propane chassis | Most propane bottles have a RH side pump and thus requires a RH side PTO with a jackshaft to connect the two. |

Turning radius: steering gears
A single gear chassis always turns sharper to the left than to the right. The steering gear, regardless of set forward or set back axle position, is the limiting factor on the LH side of the frame. The biggest reason you can’t turn as sharp on a set forward axle is tire to gear conflict, where on a setback axle the limiting factor is tire to draglink. Dual gears result in generally the same turning left or right due to both gears.
