Description for Fox Factory IFP-R QS3 Shocks

FOX's IFP-R rebound adjustable design, combined with vehicle specific damping and linear spring rates gives you a confident connection to the road while soaking up the bumps, mile after mile. With an internal floating piston to separate the nitrogen gas from the shock oil, the IFP-R shocks will maintain damping control no matter how long you ride. The IFP-R's wide range internal rebound control also has 12 distinct clicks, allowing you to tune the exact rebound rate to balance out your spring preload and keep your rear wheel firmly planted on the road.

• Gas-charged mono-tube, with Internal Floating Piston and Rebound adjustment (IFP-R)

• QS3 - 3 position quick switch rebound adjust

• 1-1/2" 6061-T6 aluminum type III hard anodized body

• 12-position externally adjustable rebound

• Spring preload setting guide marks

• Fully rebuildable and revalveable

• Advanced high-flow, deflective disk, velocity-sensitive damping

• 5/8" low friction, super-finished hard chrome shaft

Used these to replace stock rears. I never tried competitive brands, but the price made these more attractive. Wow - what a difference in the ride. I would've made the jump much sooner if I had known what I was missing. Only downside is that I'm noticing how bad I need to do the fronts now and the Foxes are hard to find at the moment. If they're ever back in stock, I'll be snatching those up as well. It's a piece of cake to replace the rears and J&Ps customer service won me over for life.

Awesome product, easy install and the Fox shocks are amazing. No regrets. J&P is a great vendor and when I realized I had mistakenly ordered the super heavy duty vs. heavy duty they processed the exchange… no questions asked and immediately shipped out my new parts. Will absolutely use them again.

Solid performing product. Replaced factory shocks on a 2022 Street Glide. I was impressed with how much the ride comfort and control of the bike felt after replacing the stock shocks. Highly recommend these shocks.

These shocks are great. Rides perfect and can't feel any bumps. Installed on my 2020 road glide special.

Alright so I can only compare to a stock suspension that I trade hard and put away wet for 63k miles. But damn this new 13” versus stock 12” (every inch matters is what I was told) is a night and day difference. The on ramp from 202 to the 60 in the east valley I would only be able to take around 70 mph and then a wobble would commence. I ran the stock Harley shocks at a setting of 21. These are the super duty Fox Factory IFP-R QS3 Shocks. I ran the on ramp and turns now at a faster speed without a wobble.

Night and Day difference from stock air shocks. Wish I put them on years ago

Great investmemt! Much better ride. Much much better with passemger. I went 13" HD on my RK SP. I run no preload to lower to that of a 12.5" shock.

to be honest this is the first time putting new shocks on my road king so all I can say is they are amazing compared to the stalk shocks and the 3 presets are distinct change in caricature I don't have that I should have payed less feeling I got exactly what Fox said they was selling and worth it!!

Putting these shocks on my motorcycle is such a tremendous upgrade I can’t describe it. Bumps it made me cringe before the change I hardly notice it has taken the somewhat unsteady feel a long sweep in corners away and the motorcycle no longer pull to the left constantly. I should have known having run fox shocks on snow machines the last 20 years what an improvement it was going to be. It’s something I should’ve done when I left the showroom floor
