2 Link Instruction and Pinion Angles

November 22, 2016

                 JIMENEZ BROS CUSTOMS 2 LINK INSTALLATION INSTRUCTIONS  
 
PLEASE MAKE SURE TO READ INSTRUCTIONS FIRST!!  DO NOT WELD ANYTHING IN UNTIL MOCK UP                                                                              IS COMPLETE! 
 
1. BEFORE REMOVING ORIGINAL REAR END MARK THE CENTER OF YOUR REAR END AXEL ON YOUR FRAME, THIS IS GOING TO PREP YOU FOR YOUR STEP NOTCH INSTALL. BEGIN BY REMOVING ALL OF YOUR REAR END OFF THE VEHICLE JUST LEAVING THE FRAME. LEVEL THE FRAME SIDE TO SIDE AND FRONT TO BACK. MAKE SURE HAVE A CLEAN AND SAFE WORK SPACE AND THEN BRACE THE REAR END. 
 
2. FIRST STEP TO INSTALLING A STEP NOTCH OR C NOTCH IS FINDING YOUR CENTERLINE (THIS WAS IN STEP ONE). YOU WILL HAVE 4 NOTCHES 2 HOOPS AND 2 STRAPS IN YOUR KIT PROVIDED. SET 2 OF THE NOTCHES IN PLACE ON THE FRAME AND LINE THEM UP WITH THE CENTERLINE. THE HIGHEST POINT OF THE NOTCH SHOULD BE TOWARD THE REAR OF THE FRAME. PLACE A CLAMP ON THE NOTCHES TO HOLD IN PLACE, THEN USE A LEVEL TO MAKE SURE THEY ARE LEVELED OUT, THEN TACK WELD IN. PLACE THE TOP STRAP ON TO THE TOP OF THE NOTCH, TACK WELD AND BEND INTO PLACE COVERING THE OPEN SPACE ON THE TOP OF THE NOTCH. THIS WILL LEAVE YOU WITH THE EXPOSED FRAME ON THE INSIDE OF THE NOTCH THAT YOU NEED TO CUT OUT.

 

3. ONCE THE FRAME IS CUT YOU WILL PUT THE HOOP IN PLACE AND WELD IT IN. THESE PIECES ARE CUT TO FIT SO YOU WILL WELD IN THEN TRIM AS NEEDED.

4. PRE ASSEMBLE ALL OF THE 2 LINK THAT YOU ARE ABLE TO WITH HARDWARE PROVIDED AND PREPARE FOR MOCK UP. PARTS THAT YOU CAN PRE ASSEMBLE ARE THE LOWER BAG BAR, TRAILING ARMS, AXEL PERCHES, AND CROSSMEMBER. MAKE SURE THAT YOUR TRAILING ARMS ARE THREADED OUT WITH JONNY JOINTS AT THE SAME DISTANCE BEFORE MOCK UP CONTINUES. ONCE YOU HAVE DONE THE PREVIOUS STEPS YOU CAN CONTINUE ON TO CREATING YOUR STEP NOTCH.  
 
5. TO BEGIN THE MOCK UP, PLACE THE PRE ASSEMBLED PARTS FROM PREVIOUS STEPS UNDER THE TRUCK AND WITH A JACK, LIFT AND CENTER THE REAR SECTION. ONCE CENTERED TAKE THE CROSSMEMBER AND CLAMP IN PLACE ON THE FRAME.  
 
6. YOU CAN NOW SET YOUR REAR END AXEL ONTO THE AXEL PERCHES AND CONTINUE LIFTING THE REAR END TO DOUBLE CHECK YOU ARE CENTERED IN THE NOTCH. AT THIS POINT YOU WOULD WANT TO CHECK THAT YOUR PINION ANGLE MATCHES THE TRANNY (SOME PEOPLE PERFER DOING 3 TO 5 DEGREES BUT THIS IS UP TO HOW YOU SET YOUR MOTOR AND TRANNY UP). NEXT YOU WOULD TAKE THE PAN HARD BAR WITH TABS AND TACK WELD AT PERFERRED RIDE HEIGHT AND PARALLEL WITH REAR AXLE TO THE STEP NOTCH. ALSO TACK WELD THE PAN HARD BRACKET TO THE AXEL. 
 
7. ATTACH YOUR AIR BAGS TO THE LOWER BAG BAR ALONG WITH THE UPPER BAG PLATE WITH HARDWARE PROVIDED. NOW PLACE THE SHOCK BAR ON TOP OF THE UPPER BAG PLATE AND TACK WELD ONTO THE NOTCHES. NOTE: THE SHOCK BAR IS A UNIVERSAL PIECE AND MAY NEED TO BE TRIMMED TO FIT YOUR SPECIFIC VEHICLE. SUGGESTED PLACE FOR THE SHOCK BAR IS AT THE TOP OF THE NOTCH TOWARDS THE REAR. AFTER THE SHOCK BAR IS IN ATTACH THE TOP OF THE SHOCKS WITH THE HARDWARE PROVIDED. 
 

AT THIS POINT EVERYTHING IS TACK WELD ONLY! NOTHING BUT THE STEP NOTCH OR C NOTCH IS A SOLID WELD! 

 
8. NOW YOU WILL NEED TO PUT ON THE TIRES TO BEST JUDGE THE ANGLE AT WHICH YOU WOULD WANT YOUR SHOCKS. PUT AIR INTO YOUR BAGS, EXTEND THE SHOCK AND MARK WHERE YOUR TAB IS. ONCE YOU HAVE THESE MARKED ON BOTH SIDES YOU CAN TACK WELD THEM ON TO YOUR LOWER BAG BAR AT THE DESIRED ANGLE. 
 
9. YOU SHOULD BE AT THE POINT WERE YOU CAN LOWER AND RAISE THE KIT TO DOUBLE CHECK THAT IT IS STILL CENTERED AND AT DESIRED HIEGHT. IF THIS IS ALL OK THEN YOU CAN GO BACK AND ACTUALLY WELD EVERYTHING THAT YOU HAD TO TACK WELD EARLIER AND REASSEMBLE YOUR REAR END COMPLETELY.
