Transmission components manufactured to be equivalent to, or surpassing OE specifications.

With over 1,542 references in our range, we can provide parts for more than 90% of the UK car parc, covering both petrol and diesel cars by all the major European and Asian automotive manufacturers.

OE Quality –

  • Trusted by the largest distributors across the globe for over 12 years – our components are provided with a 3-year manufacturer’s warranty as standard.

Manufacturing –

  • BGA uses OE (original equipment) parameters and tolerances as the mandatory MINIMUM requirements to pass our quality controls – meaning that our components can and will often surpass OE.

Heritage –

  • BGA emerged as the aftermarket division of the 4BG Group, a leading OE Gasket and Engine component manufacturer formed in 1929 producing more than 128 million components annually.


  • We supply a range of comprehensive Drive Shaft and CV Joint Kits to provide our customers with an all-in-one solution which has been developed by our Technical Engineering Team to ensure consistent quality.
  • Our Drive Shafts are 100% inspected with “go / no go” spline gauges to ensure that the critical tolerance of our shaft splines is accurate. Hardness testing of all components is also undertaken in-house to ensure longevity.
  • The range has been engineered to perfection and tested endlessly on bespoke real-life simulation machines in BGA’s UK headquarters to match and exceed that of OE equivalent.
