FAQ

Is installation of webshop parts possible

We have a workshop where we can provide assembly for many parts such as:

  • Driveline, locking differentials, clutches, flywheels and axles
  • Suspension, wishbone bushings, subframe, coilover kits, stabilizer bars shock absorbers and springs
  • Suspension alignment and weighting
  • Interior, sport seats, short-shifters
Is the stock indicated by the shop correct?

Yes, the stock indicated by the webshop is the stock as we have registered it locally at our location in Kruiningen.
Is that 100% error free, no there is a chance that parts are counted incorrectly or taken out of stock without registering this. We keep regular counts to correct this, but a mistake is always possible.
 

Additionally, where possible, we also try to indicate stock at the supplier, as with the product below.

Our local stock is 1 piece (Items). But as indicated in addition, the supplier also has these in stock so we can have new parts in quickly as well.

We also have this page with estimated delivery time for backorder parts:

How long does a differential or transfer case overhaul take

Most of the overhauls we offer are 1 work day work, differential overhaul plus any modifications to the LSD, haldex or an lsd overhaul.
Larger jobs requiring metal machining or other cnc and reïnforcing work, we will explain the situation on a case by case basis and give an indication of processing time.

Usually our overhaul schedule for the next month is full and so we can only schedule after that time.

Is shipping outside the Netherlands or Europe possible?

Yes, we can ship virtually worldwide with competitive rates. The webshop shipping rates can be a bit rough at times because we cannot enter every type of weight for every destination and update if the rates change again.

Therefore, please contact us for a customized proposal.

Is your differential not yet in the shop?

We offer rebuilds for many differentials of all brands. But we haven't literally had all models in our hands. The ones we have in the webshop, we've actually rebuilt those before.

But if your differential isn't listed, it doesn't mean we can't overhaul it, but probably we'll have to look at it to order the right parts and possibly make a tool to cleanly rework everything. So feel free to ask what the terms and a cost estimate is for your model.

Will my order be shipped today?

Our pickup for DHL packages is around 3pm every day. Orders that we get in before 13:00 and are in stock we can then normally get shipped that day.
 

Large packages or to distant destinations may go by UPS, Fedex, PostNL or other package delivery companies and may not be picked up until the next day.

Can you adjust a limited slip differential?

Yes, it depends on the type, but we can modify and tune virtually any limited slip differential. We have extensive experience in tuning and customizing plate-type differential setups for every purpose: from street use to endurance, rally, drift and off-road. In addition, we are the specialist in Europe for tuning OS Giken Superlocks, with which we have delivered competition-winning setups inside and outside Europe.

We also repair Torsen-, visco- and electronically driven locks. Here we combine our technical precision with in-depth knowledge of driving dynamics and chassis engineering for the ultimate setup in any situation.
