ARBs new Air Locker(TM) Shim Driver is a professional automotive differential service tool for installing/servicing common shim pre-loaded differentials. Insufficient carrier bearing pre-load can result in premature bearing failure and ring and pinion failure in all differentials, and possible oil/air leakage issues in an Air Locker(TM) differential. Most common Salisbury style axle assemblies(e.g., Dana Spicer model 44) require the pre-load shims to be tapped into place in order to achieve the required pre-load during set-up. Tapping shims into a tight space from a single point on the outside edge of the shim can cause damage to the shim and render it useless, resulting in extra cost and labor to the installation. As part of ARBs new Air Locker(TM) Tools range of differential service/installation equipment, ARBs Air Locker(TM) Shim Driver is comprised of 6 different sized steel profiles designed to evenly distribute the installation force (from tapping) around the outside edge of a differential shim as it is tapped into place in the assembly. This allows thinner shims to be inserted into tighter places than would be possible without the Shim Driver.

Warranty
  • Comes with a size range to suit most common carrier bearing shim diameters
  • Reduces the risk of damaging carrier bearing shims as they are installed
  • The set of drivers are joined together as a set for convenience
  • Air Locker Shim Driver Set
  • Zinc plated finish

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
