shock upgrade

Post by kolot »



I have an 03 GL1800 and would like to upgrade the rear shock, I was planning on a progressive spring but I found a shock from a trike conversion for short money. The shock is off a 2014 wing and has 26 miles on it. I thought I had read somewhere that around 2012 the wing shocks were upgraded . I was wondering if the shock will have any fitment issues? Plan would be to upgrade the 14 shock with a braided line, progressive spring and bleed actuator then make the swap.

With what you intend to do, you will already have the old rear suspension removed. You could just rebuild it, if you find the 2014 parts are not compatable. You will be able to compare them also, so you are going to be the resident expert shortly. Please report back on this, and let us know if the 2014 parts fit, or if you rebuilt your older parts and put them back in. Thanks.

And it changed again in '11: http://www.partzilla.com/parts/detail/h ... A-A62.html

Hope this helps some.
Honda part numbers are very consistent. The first five digits are the part number. Second three are for the make model, and the last three are manufacturer. These three numbers should fit your bike.

An example of this is the front crank seal on a 1200 and 1500. The 1200 number is 91201-MG9-005 (35X59X8). The 1500 seal, same size is 91201-MN5-003.

long time coming but finally tore into the bike and changed out the shock. It seems that the shock is the same from 01 right up through the new style in 2018. The shock I used was from a 2014 and it went in without issue. I changed the spring in a press with a tool I fashioned from a 2" water pipe with a slot cut in it to clear the boss where the brake line screws on. Have not been on the test ride yet but I can tell you my preload did not kick in till 10, now after a bleed and top off of the reservoir, the preload works immediately from 0 right up the 25 and I can actually see the spring being pushed right off of 0.

I replaced my rear shock and spring over the winter with a setup from a 12 with very low miles. I did not change the spring to a progressive, I understand it's a bit to tight for my style of riding.
Mostly one up. You will definitely feel the difference and mostly on how bad or how saggy your original shock spring was.
Per traxxion there is absolutely no difference is shock and spring from 01-17 but like previously said its different manufacturer's.
The next time I do mine I'll just replace the spring with oem. I like the ride and most of it is without my pillon.
It's not what you buy, it's what you build.

Any newer spring than what you have, as well as a newer shock will be a huge improvement over one with many miles on it. Basically, if you replace the spring/shock assembly, the rear will ride like it did when it was new. Most who bought their Wing new, were very impress with how well their 5th gen rode and handled when it was new. As their mileage racked up is when they began to complain about the ride. If you OH the front forks and replace the springs with new OEM, and so long as the steering head bearings are tight, you will then have a new riding and handling Wing.
