**Only works with ATS v1.39** Proudly introducing the Detroit Diesel 60 Series Sound & Engine Pack. All sounds were recorded from a Freightliner FLD120 with 60 Series engine fitted with straight exhaust and muffler with approximately 6 onboard perspectives including microphones mounted at the engine, exhaust and in the cabin. The sound setup features custom attenuation curves for the engine and exhausts meaning that the volume of each sound source can be heard differently at various distances, or when the vehicle passes the camera. This pack only contains engines sounds. No other sounds are included. A number of engines are included that I have carefully designed with references available online. Engines included: DD60 380 (12.7L) DD60 380 (12.7L)(Silencer) DD60 455 (12.7L) DD60 455 (12.7L)(Silencer) DD60 425 (14.0L) DD60 425 (14.0L)(Silencer) DD60 515 (14.0L) DD60 515 (14.0L)(Silencer) DD60 619 Tuned (14.0L) DD60 619 Tuned (14.0L)(Silencer) Compatible with the following trucks: Default: - Kenworth T680 - Kenworth W900L - Peterbilt 389 - Peterbilt 579 - International Lonestar - Western Star 49X - Freightliner Cascadia 2019 Modded: - Freightliner Classic XL (by Jon-ruda) - Peterbilt 389 (by Jon-ruda) - Kenworth W900 Highway Killer (by Jon-ruda) - Kenworth K100E (by Overfloater) - Peterbilt 389 (by Viper) - Kenworth T610 (GTM) <-- Currently having problems with this one. - Kenworth T800 (GTM) - Kenworth W900B (GTM) - Peterbilt 567 (GTM) - Freightliner FLC (By XBS)
