MZS Swingarm Spools 8mm — Aluminium Paddock Stand Bobbins with Stainless Bolts

MZS 8MM Swingarm Spools are aluminum paddock stand bobbins designed to protect your motorcycle’s swingarm and allow secure lifting with an 8mm-threaded paddock stand.

These MZS spools are a universal, easy-to-fit accessory made from 6061-T6 aluminum with stainless steel bolts and four included washers to help achieve a snug fit. They serve two practical purposes: they act as sacrificial contact points if the bike tips, and they provide stable engagement points for most rear paddock stands sized for M8 threads. Before ordering, verify your frame’s spool mounting hole accepts an 8mm (M8 x 35) screw to ensure compatibility.

Will these spools fit my motorcycle’s swingarm?

The spools are built for motorcycles that accept an M8 (8mm) spool bolt — many street, sport and dirt bikes use this size. Confirm the threaded insert size in your swingarm and measure bolt length clearance; the package includes washers to help accommodate slight variances.

• Thread size compatibility: M8 (8mm)
• Common fit: sport bikes, street bikes, many dirt bikes
• Included parts: 4 stainless steel bolts and 4 washers
• Tip: add washers if spool doesn’t sit flush

How do these spools protect my bike and help with maintenance?

Mounted spools lift the rear of the bike by giving paddock stands secure contact points, making chain, wheel and suspension tasks simpler and safer. In a low-side or tip-over, the spools act as replaceable sacrificial pieces that take the abrasion and impact instead of the swingarm’s finish.

• Provides solid anchor points for rear paddock stands
• Reduces direct swingarm damage in small drops
• Easy removal and replacement if damaged
• Lightweight aluminum minimizes added weight

What are these spools made of and how durable are they?

MZS spools are machined from 6061-T6 aluminum alloy with stainless steel bolts, chosen for strength, corrosion resistance and impact tolerance. The metals resist rust and fading under normal road and garage conditions, while the design balances durability with lightweight convenience.

• Body: 6061-T6 aluminum alloy for strength
• Bolts: stainless steel for corrosion resistance
• Finish: anodized or machined surface to limit wear
• Longevity: built to withstand regular paddock stand use

How should I install these spools and troubleshoot fit issues?

Installation is straightforward: thread the stainless bolts through the spool into the swingarm mounting holes, tightening to manufacturer torque spec. If the spools do not sit flush or feel loose, add the included washers between the bolt head and spool to achieve a secure fit. Contact MZS technical support for missing pieces or damaged items.

• Step 1: Clean mounting holes and threads
• Step 2: Insert bolt through spool into swingarm
• Step 3: Tighten to recommended torque (consult bike manual)
• Step 4: Use washers if spool doesn’t set flush

Who this is for: Motorcycle owners who routinely use a rear paddock stand, perform wheel and chain maintenance, or want an affordable way to reduce cosmetic swingarm damage. These MZS 8MM swingarm spools suit riders of many sport, street and off-road bikes that accept M8 spool bolts and who value durable, lightweight hardware that’s simple to install and replace.
