The Mercedes Sprinter Terrain & Launch Class B RVs by Jayco & Entegra Coach come with an on-board air compressor which is great but the factory plastic air line is not. The plastic air line is prone to damage and has a very low temperature rating, making it susceptible to failure. Agile Off-Road has developed a On-board Air Upgrade Kit that works for both Jayco Terrain & Entegra Coach Launch vans, which includes heavy duty stainless steel air lines and an ARB switch to increase PSI.
The included ARB switch increases air pressure from CLOSED/70 PSI and OPEN/100 PSI to CLOSED/135PSI and OPEN/150PSI.
