Rear Lowering Block help.

I ordered some of the rear lowering blocks from Burly Brand for my 93 FXR. It came with instructions but no illustrations. The instructions do not make sense to me. I am no dummy when it comes to mechanical things like old cars etc, etc. I just want to do this right. Has anyone installed these on a FXR Super Glide and if so, could you show some pics?

Thanks
Bobby

Looks straight forward . Following the instructions with the rear off the ground , remove the shocks then pull the axle out . The lowering blocks should be marked left and right . Put the axle back in with the correct mount , axle goes thru the hole with the shock mount pin to the rear . Put the axle back thru the wheel hub then put the other side block on . Install the shocks before tightening the axle nut . Get everything positioned , shock bolts tightened then the axle nut . That should be all there is to it .

*Read all the instructions carefully before installing this kit on your
motorcycle. Use your Harley-Davidson manual as a reference while
installing this kit.

*Support and lift the motorcycle securely so the rear wheel is just off
the ground and able to spin with light brake drag. The balance point is
between the engine and transmission.

*Loosen the upper shock bolts. Remove the lower shock bolt and
washers. Save these parts as they will be re-used with this kit. At this
point it is helpful to tilt the shocks up and back then re-tighten the
upper shock bolts.

* Remove rear belt guard mounting bolt/nut (longer 1/4-20 bolt/nut
hardware is provided for proper engagement).

* Position lower brackets onto left and right of swingarm being sure to
place end with spacer into clevis mount (stock shock position hole)
with spacer facing out. Use stock hardware (1/2-20 bolt/nut) to
secure lowering block to swingarm. Tighten bolts securely.

* Install belt drive guard being sure to locate guard's rear mounting tab
between the lowering block and swingarm clevis mount. Use 5/16-
24x1” bolt/nut (provided) through the 1/4” slot in lowering block to
secure in place (this new bolt/nut goes through lowering block, belt
guard mounting bracket, then into swingarm plate with locknut on
backside of swingarm). Tighten securely.

* Loosen upper shock nuts and position lower shock eye into new
lowering block (lift swingarm or tire/wheel to align or lower motorcycle
slightly. Use new 1/2-20 by 1-3/4 bolts and 1/2-20 nylock nuts
(provided) being sure to use a washer on front side of shock eye
before inserting bolts. *NOTE: On left side of swingarm secure rear
mount of belt guard with the same new shock eye bolt. Tighten
securely.

* Lower motorcycle and check preload (shock spring stiffness).
Adjustment may be necessary to suit personal preference in ride
comfort. Read your Harley-Davidson owners manual for procedure.




It's just like it reads.


Use Locktite on the nuts.

Do not tighten shock hardware until bike is on the ground, or else the rubber bushings will twist, as you had no preload on it, when tightened and it'll want to twist when you drop it.

Thanks, yeah I just need to get more familiar with the bike. I am so used to old cars. previous said remove axle. That doesn't sound right to me. I know thst the idea behind this mod is to move the lower part of the shock more back.

True, it moves the lower shock mount point back. However, I found it easier to remove the rear wheel too, (like Schmidty said) because the swingarm hardware goes in, from the inside of the swingarm (wheel side) to the outside in order to be correct. At the most, the old hardware has to come out, and the right side bolt won't clear the rear brake caliper mount. The instructions "fail" to mention that.....

You can try to fish it around the belt pulley and brake caliper mount by moving it, but....

I found it easier to drop the rear wheel, do the deal, and be done with it, with no hassles, bolt-fishing, less cursing and the job was done right.

Okay , based on the pics I take back removing the axle . It appears that this particular lowering kit doesn't pivot at the axle , it bolts into the original shock mount location , extends rearward then the shock mounts into the hole . The middle hole would get one of the smaller bolts to secure the mount to the swingarm and keep it from moving up or down . It looks like the hooked end of the mount would catch the end of the axle adjuster and the shock eye would then be above the adjuster screw .

Note that raising the rear and unbolting the shocks will leave the

wheel and swing-arm assy unsupported, you'll need to support both the bike frame

and the wheel and swing-arm assy as well, separately, and being able

to raise and lower both may be necessary to reconnect the shocks.

You're not going to be able to compress the spring, but it might

simplify things to change them to their shortest setting first.

We put a couple on our 08 Ultras and it only took about 15 minutes at the most on the first one and about 10 minutes on the second one.
We lifted the bike in the center to support it with the rear wheel just off the table and unbolted the lower end of the shock, installed the lowering block, and re-installed the shock lower end mounting hole on the rearward hole in the lowering block. After tightening and checking the bolts we lowered the bike and were done.
You want to check for the correct torque for the shock mount bolts (35-40 ft/lbs for the Ultra, YMMV).
Good luck.
We didn't notice any adverse effects to lowering the rear 1 inch.
