Ready-to-Mount Race Performance for the Pro-Line PowerStroke Oil-Filled Shocks
Ready-to-Mount Race Performance

PowerStroke shocks come pre-filled with 200CST oil and medium springs installed, so you can mount them straight out of the package. Designed as a true bolt-on upgrade, they instantly improve damping consistency, reduce bounce, and increase high-speed stability, making them the perfect first upgrade for any Micro-B/T.

CNC Aluminum Strength & Precision for the Pro-Line PowerStroke Oil-Filled Shocks
CNC Aluminum Strength & Precision

Built from CNC-machined aluminum with copper anodized shock bodies and black anodized caps, PowerStroke shocks offer superior strength over stock plastic units. The rigid construction enhances damping precision, improves durability, and maintains consistent performance under racing conditions.

Emulsion Oil-Filled with Bleeder Control for the Pro-Line PowerStroke Oil-Filled Shocks
Emulsion Oil-Filled with Bleeder Control

The emulsion-style oil-filled design includes a bleeder screw and robust copper washer gasket system to ensure proper sealing and consistent rebound. This setup allows drivers to fine-tune suspension feel for different surfaces and driving styles, delivering predictable control lap after lap.

True Tunability On the Fly for the Pro-Line PowerStroke Oil-Filled Shocks
True Tunability On the Fly

Dial in ride height and spring preload with adjustable threaded collars for fast trackside tuning. Whether you're fine-tuning for grip, stability, or jump landings, these shocks provide real suspension adjustability that stock units simply cannot match.

Fully Serviceable Design for the Pro-Line PowerStroke Oil-Filled Shocks
Rebuildable & Cross-Compatible

Designed with racers in mind, PowerStroke shocks are fully rebuildable using PRO643410 components. They are also cross-compatible with LOS-1991 springs, expanding tuning options and ensuring your Micro-B/T suspension evolves with your driving style and competition needs.

We want to make sure your delivery goes smoothly, so here are some important details about our service:

  • For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
  • Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
  • Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
  • If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
  • We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
  • As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
  • If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
  • For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
