Customer Reviews

Exceptional performance out of these

By   on  Verified Purchaser

Excellent shocks, these made a huge difference in ride quality especially noticed in corners, I really wish I had spent the money on these earlier for my 2013 roadglide.

FOX IFP-QSR 13" Shocks

By   on  Verified Purchaser

Excellent shock for the price. Made in the USA, Rebuildable, and a definite upgrade from the factory air-shocks. If you're looking to be under $500.00 then this is not for you. Drag Specialties might be better for you.

Fox rear Harley shocks

By   on  Verified Purchaser

I waited 5 years too long, Great ride, perfect for two up riding or solo.

Can't go wrong with Fox shocks

By   on  Verified Purchaser

Well worth the money. Easy adjustments for fine tuning my ride.

Highly recommend!

I quickly installed the parts and rode the motorcycle. I was very satisfied with with the ride performance.

Surpassed my expectations

By   on  Verified Purchaser

Wish I put these on my streetglide sooner, surpassed my expectations.

Great ride over stock

By   on  Verified Purchaser

Great ride over stock. Just ordered the fronts to match.

Great product

By   on 

I have fox shocks heavy duty on my 2001 flhtcui and my 2016 flhtk, they make a 100% ride and handling improvement over air ride shock, fox great product.

Big difference!

By   on  Verified Purchaser

Should have changed the factory shocks when I purchased my 2015 Street Glide special.

Great Shocks

By   on  Verified Purchaser

Great shocks. 100% improvement over stock on my bike. I wish I would have put them on a long time ago. I will be ordering the fronts as soon as they are off back order.

Thank you.

By   on  Verified Purchaser

I have a very high quality, very comfortable set of shocks that I got at a great price with very good customer service.

I don't know why I waited so long

By   on 

I replaced my stock shocks on my 2015 street glide special with Fox Shox IFP-QSR Standard shock 12" I don't know why I waited so long, good ride, excellent shock and a good price

Ride Fox

By   on  Verified Purchaser

Super happy about my new Fox Shocks.

These are great shocks and the price is very reasonable.

By   on  Verified Purchaser

I absolutely love these shocks and the install on my Road Glide was very easy. I paid $600 more for a pair of Russ Wernimont shocks for my Street Glide and wish I would have installed Fox Shox.

Questions & Answers

I weigh 210 the wife is around 155, we ride together 90% of the time. Which should we get, standard or heavy duty?

It would be recommended to go with the heavy duty shocks for the combined weight.

By Andy

Im looking at the Fox Shox IFP-QSR Heavy Duty Shocks 13" for my 2016 street glide special. How much sag is required ? Im trying to stay around the stock height since I have a short inseam.

Fox Shox states that the 13" shocks should measure between 11-7/8" to 12-1/8" between eyelets with rider and passenger on bike.
