We offer a range of car servicing options at A1S Modifications, but we also provide more involved engine repairs, maintenance, and upgrades for standard and performance cars.

The list is endless, but more ‘standard’ work includes everything from cam belt replacements, compression testing and resolution and head skimming to new gaskets, bearings, bushes, etc.

We are Subaru specialists and work with standard, mild tuned, and highly modified Subaru’s providing all engine work from general maintenance to major performance work.

Our highly experienced mechanics have a wealth of knowledge in Subaru engines and other vehicles so please give us a call on 01482 329534 if Subaru engine work in Hull, or engine repairs and maintenance on any other vehicle.


Gearboxes are complex things but we’re experts in gearbox repairs in Hull.  Before we start any work we’ll talk to you about any changes that you’ve noticed and do some initial fault diagnosis to help us determine where the fault lies. It might just need a small repair or possibly something more involved, or it might be different all together such as an issue with your clutch, so we’ll determine that from the beginning.

We’re experienced working with manual gearboxes and automatic gearboxes, as well as performance gearboxes, from repairs and maintenance to complete replacement, all with a great service and excellent price.

Our fully trained mechanics will explain things thoroughly and answer any of your questions so please give us a call on 01482 329534 if you need gearbox repairs in Hull.
