MEASURING GUIDE
Measuring wheel bolt pattern
4 / 6
4 or 6 lug wheels
Measure center-to-center between studs directly across from one another.
5
5 lug wheels
Skip one stud and measure from the outside edge of one stud to the center of the other.
DOUBLE BEADLOCK CLEARANCE
Will your brakes clear?
13.5"
BEADLOCK INSIDE DIAMETER
Measure from the center of the axle to the outermost point of the brake caliper. That measurement must be less than 6.75".
< 6.75"
CENTER OF AXLE → OUTSIDE OF CALIPER
INSTALLATION GUIDE
Tire mounting & beadlock torque
20–22FT/LB≈ 250 IN/LB
01
Tires should be mounted using good tire-mounting practices and equipment designed for the tire industry.
02
Before mounting, lubricate the beadlock bolt threads with anti-seize.
03
Seat the tire bead into the shoulder of the beadlock inner ring.
04
Install the outer ring and tighten the bolts in a criss-cross pattern to apply even pressure.
05
Torque the bolts to 20–22 ft/lb (approximately 250 in/lb).
06
The outer ring will flex to match the tire bead and should pull down to meet the inner ring.
07
After the first pass, re-torque the beadlock bolts.
!
DO NOT USE AN IMPACT WRENCH TO INSTALL BEADLOCK BOLTS.
Impact tools can over- or under-tighten the hardware. Start every bolt by hand to avoid cross-threading, then torque evenly.
