Mountain Bike Suspension Bushes Stainless Steel 1/2″ x 1/2″ (12.7mm x 12.7mm) – 6mm, 8mm and 10mm bore available. Manufactured by Profin Components.

Each kit contains 2 x spacers, 1 x low friction poly bushing and stainless steel mounting hardware. If you want to change the shock hardware in 2 x shock eyelets you will need to order 2 kits.

Free U.K. Shipping on orders over £15. Trade enquiries welcome.

Made with tight tolerances and quality materials – stainless steel with acetal spacers. Every kit is supplied with a superior low friction polymer bush.

Why Steel?

Numerous mountain bike suspension bushes are available on the market made from materials such as anodised aluminium, brass, steel and grade 5 titanium – our aim was to produce the hardest wearing kits at the most attractive price of any retailer.

We made prototypes from all of the aforementioned materials and subjected them to months of real world testing with various riders around the U.K. Of course there is readily available data for all of those materials online for tensile strength, Rockwell hardness, density and so forth but our concern as mountainbikers is the partial rotation backwards and forwards within the shock eyelet bushing and how well the material holds up before changes to the critical outside diameter are noted. The two class leaders in this department are 303 Stainless Steel followed Grade 5 Titanium.

Titanium has a weight advantage over stainless steel but for perspective a 22mm x 8mm stainless bushing weighs 13g to 7.5g for a Grade 5 Titanium equivalent. However even though Titanium has a greater tensile strength it scratches and wears more quickly than Stainless Steel, we decided that a rider was unlikely to notice a 5.5g weight difference but they would notice when they had to change their hardware. We settled on Steel.

So if Stainless Steel is so great why isn’t everyone using it?

The only real issue we could see with stainless steel is how difficult it is to machine. Even free machining 303 Stainless Steel is hard on tooling. Tool breakages and tool wear significantly add to production time and cost. Our tolerance on the outer diameter of our stainless steel parts is +/-0.005mm, extremely tight,  to ensure that the part fits correctly in the eyelet bushing and is free to rotate without play. That kind of tolerance is difficult to maintain, even more so when working with stainless steel.

Investment to reduce the cost

The reason that our shock bushing kits are the most competitively priced on the market, despite being made of stainless steel is because we have invested heavily in machinery and process. We manufacture in quantities of thousands, not tens, this ensures that we have stock ready to dispatch and keeps the cost down for our customers.

Which width of MTB Shock Bushing should I buy?

You can either check the manufacturer’s tech sheets to see if they have published the size for your bike or preferably just measure them yourself with a vernier gauge, you won’t be able to get an accurate reading with a tape measure.

First measure the bolt diameter, it will be 6mm, 8mm or 10mm like so:

Then measure the width:

I was going to book my rear shock in for a service, can you measure the old mountain bike suspension bushes and fit replacements for me during the service?

Absolutely no problem at all. Just book your rear shock service here and add either one or two replacement shock mounting kits to the basket – be sure to send your old kit with your shock so we can replace them with the correct size.

Don’t forget you will need a DU Bush tool to fit your new Offset Bushing – we made this high quality CNC machined tool right here in Lancashire.
