MTB fork seals are a vital protective part of the overall front suspension system, with a crucial impact on riding comfort and trouble-free operation in the harshest environments. This completely redesigned fork seal - adding on to SKF's well established fork seals range that has already been available on the market for more than 10 years - consists of newly developed rubber compounds and new geometries for both the scraper lip and the sealing lip. The co-molded combination of compounds, together with improved sealing lip properties, offers enhanced followability on the shaft. In addition, there is a new metal insert and an open wound spring on the dirt scraper lip, effectively preventing the ingress of contaminants. Fits FOX Air 40mm, All Models Extended sealing capability Improved contamination exclusion Reliable protection of the interior fork mechanism Minimum friction for enhanced control SKF Dual Compound Seal Kit Seal Kit EAN: 8050616065940

This upgrade kit includes (1) Fox 34 GRIP X damper This upgrade allows you to independently adjust High & Low Speed Compression and Low Speed Rebound.

The Wolf Tooth axle uses a captive steel washer under the head to reduce friction on the fork leg. This protects your expensive fork, transfers more of the tightening torque to clamping load for a stiffer interface and prevents the axle from sticking or galling when you want to remove it. These are also a great replacement option for lost or damaged stock axles. Always apply a small amount of grease to the washer and threads when installing.

Make a good fork a great fork. Introducing the Luftkappe air piston kit for Fox Float forks. The Luftkappe is available for: 34 Float NA2 (2016-17) Performance & Factory Series (130mm + only - 120mm and lower need the 2018 Evol air shaft before a Luftkappe can be fitted) 34 Float NA2 Evol (2018+) Performance & Factory Series 36 Float NA2 Evol (2018+) Performance & Factory Series 36 Float NA (2015-17) Performance & Factory Series (max 180mm travel, min 120mm travel) Pinkbike: "The Luftkappe's change to the feel of the Lyrik was immediately noticeable on the trail. Traction was increased across chatter and the fork remained higher in its travel and more stable, improving the dynamic ride height without sacrificing the top end. My confidence soared when hitting sections with a lot of chatter and mid to large-sized hits, and the result meant more comfort and speed through such sections." Taking everything we learned with the Corset air sleeves and the Luftkappe we developed for the Pike, Yari & Lyrik, this second generation Luftkappe is a new air piston assembly for Fox's 34 NA2/Evol and 36 Evol forks. User installable and simple to set up, the Luftkappe transforms a good fork into a great fork. Softer initial stroke Larger negative air chamber Increased sag without the associated diving Coil-like initial & mid-stroke spring rate without excessive bottoming Increased sensitivity Improved mid stroke support & control Superior bump compliance and traction Reduced hand fatigue Reduces required compression damping Retains volume spacer compatibility Optional tools available for self-install What's included in the kit: 34 Evol: Upgrade low friction air piston assembly. 34 NA2: Upgrade low friction air piston assembly & upgrade low friction, low profile sealhead 36 Evol: Upgrade low friction air piston assembly. 36 NA: Upgrade low friction air piston assembly & upgrade topout spacer ring Note: If your 36 Evol tops out noticeably, you will need to replace your air shaft assembly before purchasing the Luftkappe. Fox have updated this part due to the topout issues that many of the 2018 36 Evol forks had. 34 forks do not have this issue. Relevant Fox part numbers for the new air shaft assemblies, by travel: 180mm: 820-02-534-KIT 170mm: 820-02-535-KIT 160mm: 820-02-536-KIT 150mm: 820-02-537-KIT 140mm: 820-02-538-KIT 100mm (36 831): 820-02-539-KIT If your fork does not have noticeable top-out issues, you don't need to replace the shaft before installing the Luftkappe. FAQ: 1. Can I install it myself? Yes, provided you have access to the supplies and tools listed in the installation instructions above. If you're really crafty (and EXTREMELY careful) it is possible to install the Luftkappes (all Evol variants) without the installation tools, however the risk of damaging things is much higher and we really don't recommend trying. If you choose to take this route and damage your air shaft (or anything else), we cannot be held responsible - we make the tools available for a reason. It is not possible to install the 34 NA2 Luftkappe kit without 10mm shaft clamps and the bullet tool - you'll damage the shaft AND damage the seals on the new sealhead. 2. Does it work with TALAS forks? No, sorry. 3. Does it work with versions of the 36 prior to 2015? No, sorry! 4. Does it work with 32s or 40s? No, sorry. 5. How does it actually work? It enlarges the negative air chamber to reduce the initial spring rate. This lets you run higher air pressure for more support in the middle and end of the stroke with improved sensitivity in the start of the stroke. 6. Is it compatible with MRP's Ramp Control cartridge? Generally speaking no. If you are running your fork at least 30mm shorter than its maximum available travel, then yes. 7. Shouldn't I just buy a new fork instead? Sure, they're about the same price as the Luftkappe. 8. What parts does it actually replace in the air spring? It replaces the plastic piston itself, and the rubber topout bumper in the 34s is removed but not replaced (36 topout assembly is unchanged). You reuse your air shaft, though the 34NA2 kit comes with a replacement low friction, low profile sealhead comparable in size to the stock 2018 Evol sealhead. This is also why the NA2 kit is more expensive than the other two - it's basically a 2018 Factory update on top of a Luftkappe. 9. Who is this NOT suited for? The Luftkappe is outright superior to the stock air spring for nearly everyone, however there are a few cases where it might not be for you: - If you run your 36 at 180mm, it will be quite progressive. You may like it, but you may also find it hard to use the last 5-10mm of travel - if this would bother you then have a think about it first. At 170mm and below it will be fine. - If you like running really low sag for some reason. The Luftkappe runs more sag than the stock fork, but is firmer in the mid stroke - similar to a coil fork, but with ending-stroke ramp up to prevent harsh bottoming. If you're the kind of person who wants the fork to run 5% sag, this isn't for you. We could point out that a setup like that probably just means your handlebars are set too low and you're compensating with oversprung suspension, but we aren't here to judge you, so maybe just don't buy it. - If you're anal about your fork having an exact (but rounded-to-the-nearest-10mm) amount of travel. Because the Luftkappe balances forces at a pneumatic topout, the force right around topout is very low (literally zero other than friction), meaning the weight of the bike alone will cause it to sag a few millimetres. Your car's suspension sags under the vehicle's own weight, so should your bike - unless it was so sticky, overly stiff or over-preloaded that 10kg of bike weight wasn't enough to cause your suspension to move at all, of course. If only having an apparent 148mm out of a 150mm fork is a big deal for you, stick with the stock fork.

Because the Luftkappe balances forces at a pneumatic topout, the force right around topout is very low (literally zero other than friction), meaning the weight of the bike alone will cause it to sag a few millimetres. Your car's suspension sags under the vehicle's own weight, so should your bike - unless it was so sticky, overly stiff or over-preloaded that 10kg of bike weight wasn't enough to cause your suspension to move at all, of course. If only having an apparent 148mm out of a 150mm fork is a big deal for you, stick with the stock fork.
