88-98 OBS Dually Arms 

Lowboy motorsports 88-98 C3500 Dually Arms come with everything necessary to convert your OBS Dually with 22" or larger wheels and lay it on the ground. We have been doing this for 3 decades and know all there is to know about the big wheel Alcoa conversions on all dually trucks. You wont find a better deal.

All of our dually conversion arms are built in house to assure that you receive the parts you want with the correct fitment for your ride as well as being fabricated with strength in mind to hold up to years of road stress. *Please note these arms can take anywhere from 4-6 weeks to be built and shipped. *

Upper an lower arms
Shock mounts
Polly bushing
L/R steering amenities
Bag cups
Frame box plates
Upper 1in uniball
Lower moog 1 ton balljoint

The set up converts the dually hub and swaps it out with a single wheel hub of the same year. Combination of the shorter hubs and longer arms effectively pulls the wheels in about 3”’per side. 

Does require a 22 or larger wheel, moves the wheel one inch forward allows you to drive lower, lifts higher and rides nicer.
