14 BOLT REAR AXLE TRUSS Single Rear Wheel (SRW)
FULL WIDTH & LOW PROFILE
NOTE: Not for use with 14 bolt VAN axles which are offset differently than Truck axles.
***This truss works best with the PG1403 - Low Mount Pinion Guard/Bridge option***
NOTE: GM VAN axles have a differential that is offset differently than a typically truck and this truss will not have equal amounts of tube on each side. The truss will still work, it just won't be perfectly centered.
THIS KIT INVOLVES EXTENSIVE WELDING ANDGENERAL FABRICATION SKILLS. ONLY COMPETENT WELDERS SHOULD ATTEMPT TO INSTALLTHIS KIT.
Tools Required :
Safety Glasses, Gloves, Tape Measure, Socket Set, Wrenches,Wheel chocks, Jack, Jack stand. CuttingTool of your choice (Sawzall, Grinder, plasma, cutting torch) Welder.

Place wheel chocks at the front wheels of the vehicle. Break free lug nuts on rear wheels (Do notfully loosen or remove lug nuts yet.)
With the vehicle sitting on the ground, Measure your rideheight at the frame and height of the centerline of the axle, Also take measurementof your wheel base.
(Make a note of this for later.)
Jack up the rear of the vehicle and set the axle on Jackstands, Remove the rear wheels from the vehicle, With the wheels removed Jack the vehicle upagain. Securely place tall jack standsunder the frame in front of the LCA or Leaf spring mounts at the previouslymeasurement of ride height. Place a 2nd sent of jack stands under the rearaxle.
Remove the existing rear axle from the vehicle. If you arestretching wheelbase back far enough foraxle to interfere with fuel tank you will also want to Remove the fuel tank andset it in a well ventilated area away from where you will be working andwelding.
Prep axle the truss will be welded onto by removing allmounts and paint/ rust. Once the axle isprepped. Slide new axle under the vehicle and place on jack stands at themeasurement of what the centerline height was at ride height also make sure itis set to the wheelbase you will be using.
Using another jack stand or block of wood set under thepinion on the axle set the desired pinion angle of your build to ensure it doesnot get changed . Now place the truss on top of the axle so it is level withthe ground and not tilted forward or backward (If yourtruss is angled it can cause upper arm mounts or the truss to twist off underload) You may need to trim somegussets on the truss to allow it to sit level depending on your wheelbase andpinion angle.
With the truss set level on top of the axle tack weld Thetruss ends to the axle tubes.
With the truss tacked into place Pull the rear axle fromunder the vehicle to allow more space for welding. Once the axle is pulled from under thevehicle. Heat the axle to about 400degrees Start to weld the gussets to theaxle and truss .When welding, Start on one side of the axle, Weld a small amount,Then move on to the opposite side of the axle to allow each side to cool. Thiswill help prevent warping .Stitch welding is preferred and welding every inch of every seam is notnecessary. Grind and clean the rosette welds on the axle. If your truss has abridge you may need to Trim the bridge depending on your pinion angle and weldit to the truss. (Optional) Stitch weld the axle tubes to the ends of the casting for addedaxle strength and to prevent the axle tubes from twisting. If you haveany Control arm mounts, Shock mounts, Coil over tabs, Track bar mounts thatneed to be welded on to the axle youwill need to place the axle under the Jeep on jack stands at ride height anddesired wheelbase an weld them on at this time in their proper location foryour specific build. Once all of thewelding is complete you will wrap theaxle in a welding blanket to slowly cool overnight.
Clean the Truss and axle of any machining oils and Prep forpaint or powder coat.
Install the axle back under the vehicle and place on jackstands. If you removed your fuel tankyou can reinstall it at this point. Install the wheels on the vehicle and tighten the lug nuts (Do nottorque them down yet.) Lift the vehicleand remove all of the jack stands and set the vehicle on the ground. with the vehicle on the ground check all ofthe bolts and lug nuts are torqued to proper specs. we recommend drawing a lineon the nut and bolt heads and where they are mounted for quick reference whenchecking for tightness after 50 miles .
