  • Jamna Auto Industries Ltd is the only company in India which provides complete suspension solutions to its customers. Our experienced and well trained design team has the capability to design Multi & Parabolic leaf springs of any kind and application of vehicle.
  • Each of our design goes through complete design verification and validation cycle which includes FEA studies, strain measurement and simulation on test rig using Servo Actuators.
  • Each design and sample goes through the stringent quality and safety tests before they are released for commercial application. These tests are also validated by external leading testing houses
  • In addition to its undisputed leadership in India JAI has successfully designed and manufactured springs for Ford Transit in Europe and General Motors Hummer in USA.
  • R&D at JAI evaluates every design and specification laid down by OEMs. Our springs are indigenously designed with cutting edge software to run a detailed analysis of the spring design on various parameters of stiffness, load, stress, fatigue life etc. Once our analysis is complete, a prototype is developed which is further subjected to stringent tests before moving further to the stages of pre-launch & regular production.
  • JAI believes in enhancing the knowledge base by participating in various world level conferences and seminars and pubishing researchpapers
