Chevy & GMC Vans

Ok guys,,need some help on flip kit install on composite spring. Here's a pic of the kit I sold. There were no directions with these parts. I've never installed one so I'm no help at all on this. Can anyone who has installed one gives us a step by step of install ?
Any help is appreciated.

hey Larry here what I downloaded from BellTech and DJM when I bought my flip w/no directions:

FLIP KIT INSTALLATION INSTRUCTIONS

CHEVY ASTRO VAN / GMC SAFARI VAN
Congratulations! You were selective enough to choose a BELLTECH PRODUCT. We have spent
many hours developing our line of products so that you will receive maximum
performance with minimum difficulty during installation.
Note: Confirm that all of the hardware listed in the parts list is in the kit. Do not begin installation if
any part is missing. Read the instructions thoroughly before beginning this installation.
Warning: DO NOT work under a vehicle supported by only a jack. Place support stands securely under
the vehicle in the manufacturer’s specified locations unless otherwise instructed.
Warning: DO NOT drive vehicle until all work has been completed and checked. Torque all hardware to
values specified.
Reminder: Proper use of safety equipment and eye/face/hand protection is absolutely necessary whenusing these tools to perform procedures!
Note: It is very helpful to have an assistant available during installation.
RECOMMENDED TOOLS:
• Properly rated floor jack, support stands, and wheel chocks
• Combination wrench set
• Torque wrench: 0-75 lb ft. range
• Ratcheting socket wrench and socket sets
• Air Chisel / Die grinder W/ cut off wheel
• Safety Glasses
! NOTICE
Please note that this kit (6630 or 6302) was not designed to be used with the factory rear Anti-Sway
Bar. You will need to use the Belltech Anti-Sway Bar in place of the OEM bar for added clearances
(Part Number 5528). This bar will also fit on a stock vehicle.
KIT INSTALLATION
1. Open the hardware kit and remove all of the contents. Refer to the part list (Page 3) to verify that all
parts are present.
2. Remove the rear wheels. Remove the U-bolts and inner axle tube retaining plates.
3. Remove the ground cable from the battery. Loosen the screw clamp on the fill tube going into the gas
tank. Pull the protective plastic shroud around the passenger side of the tank away from the body. This
will most likely break the plastic fasteners. New ones are provided in the hardware kit. Unscrew the
four bolts holding the gas tank support straps in place. The fill hose will pull away from the tank.
CAUTION: Let the tank down slowly so the connecting hoses won’t be damaged. Gasoline fumes are
extremely flammable; extinguish all open flames and no smoking during this period of time. (Picture
#3)
4. Remove the two bolts holding the front springs into the hanger housing. Save these bolts for use in reinstallation.
(Pictures #4 & #5) Lubricant may have to be used in aiding the bolt removal. Lower the

floor jack slightly so the spring bracket will slide out of the hanger housing. (Picture #6) (Note: Power
tools may be of help in the removal and re-installation process.)
5. Remove the bottom bolts on the rear shackles. Lower the floor jack slightly so the rear spring bracket
will slide out of the shackle. Remove the upper bolts holding the shackle to the frame. Remove the
stock shackle and save stock mounting bolts for use in the re-assembly process. (Picture #7) Note the
direction of the stock shackles to be able to install the new shackles in the correct direction.
6. Remove the fiberglass spring assemblies from both sides of the vehicle, by prying the rear axle perch
assembly away from the rubber cushion from the spring. (Picture #8)
7. Carefully remove the spring saddle away from the rubber spring cushion. Be careful not to damage the
rubber cushion. Again, do not remove the upper or lower rubber cushion from the spring.
8. Apply the lubricant on the rubber spring cushion. Place the new saddle on the rubber cushion. (NOTE:
There is a right and a left side on these parts, the portion of the saddle that has the up right
welded edge with the recess for the axle tube faces out on both sides.) Line up the ridges on the
cushion and the recesses on the saddle and set into place with a rubber mallet.
9. Install the front spacer plates into the spring hanger pockets with the joggle in the plates out away from
the spring pockets and the slots facing up. Slide the round spacer tubes between the spring plates and
use the new 9/16 by 6” bolts and nuts to connect the assembly together. Snug these only, you will
tighten these later. (Picture #9)
10. Slide the spring assembly under the rear end housing. You will have to raise the axle housing some for
the next steps.
11. Open the brake line clamp on the axle housing and slide the steel line out of the clamp and away from
the housing slightly.
12. Lift the front of the spring up and fit the spring into pockets between the new spacer plate. Slide the
stock hanger bolts through the front holes of the spacer plates and springs. Lift the rear of the spring
higher to line up the rear holes and slide the rear two bolts through the other holes in the plates and
springs. (Picture #10)
13. Install the new rear shackles to the frame using the stock hardware removed in step #5. Lift the spring
into place in the bottom portion of the new shackle and insert the stock bolts. Thread on and snug
these bolts only. You will tighten these later. (Picture #11)
14. Lower the axle assembly into place, making sure that the steel brake lines are cleared. The vertical
tabs on the new saddles will position themselves into place in the spring perches on the axle when the
axle is at rest. (Picture #12) Caution: Be certain the saddle tabs seat inside the axle perches.
15. Install the new U-bolts over the axle and through the new saddles. Place the new bottom plate with the
dimple facing down away from the springs, on to the U-bolts. (Picture #12) Insert the two short spacer
tubes between the axle spring perch and new saddle. (Picture #13) Insert the 7/16 by 3” hex head cap
screws (2) through the spacer tubes, saddle and new lower plate. Place the new locking nut on the Ubolts
and 7/16 cap screws and snug tighten only. Lower the floor jack completely so that the axle
assembly is in its correct position. Re-check the axle location, making sure the brake line clearance is
sufficient.
16. AT THIS POINT, TIGHTEN ALLTHE NUTS AND BOLTS, FRONT, REAR, AND CENTER. ITS
IMPORTANT TO DOUBLE CHECK THIS PROCEDURE, MAKING SURE THAT ALL HARDWARE
HAS BEEN TIGHTENED COMPLETELY.
17. Lift the gas tank and re-install reversing the procedure in step #3.
18. Re-install the rear wheels, lifting the rear end with the floor jack if necessary.
19. When wheels are on, installation is complete.
20. After 1,000 miles, check and re-tighten all hardware used in the installation process. Repeat this
operation every six months.

ok the two plates that have the big holes in the middle go under the leaf after flipping the axle onto the top of the leaf then there should be 4 total plates (if this is the belltech kit) that will move the stock leaf spring shackle down (the Two Front shackles and the gas tank needs removed to do the driver side one) then theres the two shackles that go in the back. I eventually took the front brackets out and just use the rear ones since the djm ones are adjustable but i had to notch the frame for this i can try to get pic of mine and how the axle sits on top of the leaves since now my drop kit is gone except for the flip part since i now bagged it

Thanks SS,,appreciate the info.

Hey SS, I am the guy that bought the kit. I would like to see a pic of your set up please. I planed on notching. If I noch the frame I can leave the stock perches and schakles in right? Just do the flip and leave everything else alone?


thanks
Zach

yes but i would still use the rear shackles b/c after i did that the driveshaft started to rub on the crossbar where the gas tank strap closest to the rear end bolts in at b/c it had more room to travel with the notch
