Axle Nut Muffler Clearance

LAC blocks don't change ride quality in any way.They are in a straight line with the shock, unlike many other lowering devices that change shock angle. Full compression even at shortest setting with the blocks doesn't come close to hitting the fender to wheel or other bad stuff.

I would suggest that you lower the muffler to a stock position by adding spacers to the top of the mufflers which bolt to the hanger bracket. In my experience only the 13 1/4" shock we make will interferer with the muffler and I just purchase Ace Hardware 1/4" spacers & 1/4" longer bolts for them. I have installed hundreds of #3~#3 shocks and found no clearance issues on a stock bike but I did not install those shocks onto your bike so your exact bike may be different those I have experience with. Feel free to call anytime as your customer service does not end at purchase. You are important to us forever.

Setting sag

Please check your sag and adjust for yourself. If you have the #3~#3 shock(?), in the directions (Unofficial Installation Guide) which I figured out for the #3~#3. Divide the stroke by 1/3rd. A #3~#3 looks like this: #3~#3: 329 +5mm/- 5 mm = low of 12 ¾”~13 9/64, Stroke: 3 1/32"/77mm. Divide the stroke by 1/3rd (77mm) 3 ÷ = 25.66 mm. i. (R-1) - 1/3rd stroke = (R-3) target (with the above rider(s) on the bike).

If you adjust the bike properly as per directions, the bike must sit at (329mm - 5mm = 324mm) - (25.55mm) = 298.45mm = 11.75 inch. You are the one setting the sag and this measurement is when you are sitting the bike so this measurement is what you must get as you did it yourself..
