Red Line ExtraLight 2.5w Synthetic Suspension Fluid

Red Line Extralight suspension fluid is a synthetic 2.5w (or 2.5 weight) fluid, extremely popular in NASCAR's professional categories, motocross, and road racing, where top engineers try to run the lightest fluid possible that maintains its viscocity and stability, allowing the shock valving and springs to perform the work, rather than the fluid.

Many motocross tuners use Red Line Extralight as a direct replacement in the front forks on Showa and Kayaba forks, with or without revalving.

Red Line Extralight suspension fluid is also known as

  • Redline extra light suspension fluid
  • Red line suspension fluid
  • Red line shock absorber fluid
  • Red line fork oil

Red Line suspension fluids change very little with temperature or with use. The foaming resistance is excellent and seal drag is minimized. Different weights can be mixed to provide an intermediate viscosity and optimise shock peformance.


SHIPPING IS FREE* for orders of £60 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £4.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.

How long will it take to get my order?

We give an estimate of delivery dates as you shop and in your basket. The vast majority of items are held in stock and dispatched from our UK warehouse and we'll do all we can to get your order to you as quickly as possible.
