Frequently Asked Questions

Will this shock fit my M8 Softail?

Yes — engineered specifically for M8 Softail models with a direct fit into the frame.

How much will this lower my bike?

The Slammer provides 1–2 inches of drop at the rear, depending on your specific model and setup.

Do I need side stand modifications?

Possibly. When the rear lowers, your side stand geometry changes — modifications may be needed to ensure the stand plants safely.

Can I adjust the preload?

Yes. A threaded preload adjuster with spanner wrench is included for tuning comfort and ride height.

What's inside the shock?

High-pressure nitrogen charge, internal floating piston, and deflective disc valving for smooth damping at highway speeds.

Look fantastic on Triumph Bonneville T120

Thanks to Stuart Fillingham's YouTube video, I bought these. Couldn't be happier. A bit heavier than I expected but that just goes to the ruggedness of these panniers.

Love. These.

The style is awesome! Love the relaxed look with all the trim to make them classy too. Easy to get in and out of...really like the flip fully open and the finger hole snaps.<br />Great bag, perfect size for the HD Street 750!

Sweet

The Dark Oak canvas bags fit my Olive Gold Harley Slim S great! The fit and finish add that nostalgic look to an already classy bike. They are a bit small, but I didn't need to move my signals to make them fit, though plate relocation would be required had I not already moved it. They are a great addition and I can't wait to show them off.

Commuting, not touring

Burley Brand Voyager throw over.

Styling looks excellent. Build quality looks good, but there are definitey gaps in the lid closures where the rain can get in. The buckle snaps are easy to open and close but the tend to come unsnapped from just normal freeway riding speeds. The bags still stay closed because of the strong clips,, but the cool-loking bucklet snap come open. Would I but them again... probably. I might look at the black ones for better weather proofing. The olive onmes do looks fantastic, though, on my flat black T100. Very easy to take off and put on; takes only a couple of minutes. I used a universal rack assembly.
