Upgrade from Mono to MultiLeaf Suspension
I wanted to remove the Monoleaf and Airshocks to make way for new Multileaf that can support the vehicle and allow me to run standard shocks for better handling and comfort.
After tons of research and trial and error I used the following:
JRS 21-221 Springs - 3 Leaf - Ordered from JC Whitney ZX942079RF ($153)
Monroe 5818 Sensatrac Shocks - Ordered from RockAuto ($50)
Shackles with Poly Bushings (2) - Ordered from Espo.com
Poly Fixed End Spring Bushings (4) - Ordered from Espo.com
U Bolts (4) - Ordered from Espo.com
Poly Axle Pads Lower - Ordered from Espo.com
Total Espo Cost - $131.07 Shipped
Complete Project Cost - About $335
The new springs are 2.5" wide from end to end, where as the old springs were 2.75" wide at the bushings.
Because of this, ESPO offers different poly bushings that properly fit the 2.5" wide bushing ends
Do not run stock bushings or Energy Suspension 3.2122 kit, they are for 2.75" wide Monoleaf!
I used a 10 or 15% off coupon for JCWhitney when I ordered! http://www.edealinfo.com/Coupons/jcwhitney.shtml
