I have owned 34 motorcycles over the past 40 some odd years and have used Progressive fork springs on many of them. They always are a big improvement over the stock springs. I purchased this set for a 2007 HD Super Glide. The hardest part of the swap is getting the oil height correct, otherwise, it's relatively easy to do.
The bike handles much better and the ride is much smoother, particularly over small bumps. I was going to change out the rear shocks, but it rides so much better, I may not.
So far so good. Bought the 412 HD 13" to replace the oem shocks on my Kawasaki Nomad 1500. Delivery was good, installation was easy, and ride is very good so far. I have not had chance to get in much riding since buying but so far riding single or two up with the setting on #3 I like. I would recommend this product.
I installed the heavy duty progressive springs.On a Harley 2006 ultra classic which bottomed out so bad ,you would feel it all the way up your spine. I installed the heavy duty springs and that cured the problem. I would recommend anyone having the problem of bottoming out to install these springs. The bike also handles better and I don't know why Harley uses unfit springs ,for the prices they charge for a bike ,why can't they use these springs...I also reccomend you do exactly what progressive springs tells you to do ..exactly the right instructions for your bike..the company is highly professional and really know how to answer questions when you call....Thanks super store ,for the fast delivery..your also a great company ,to do business with..
Ordered for 2001 F650GS, did not fit. Called Motorcycle Superstore to confirm they were the correct ones, and they said they were. Ordered OEM seals from Bike Bandit and they were a full 2 MM larger than these.
