## Abstract

An adjustable floating traction bar is disclosed. The traction bar comprises a rigid body having a threaded portion on a first distal end to receive a threaded eyelet having a spherical joint to provide a connection point to an axle of a vehicle. The traction bar further comprises an opposing distal slip end being machined and fitted with a UHMW (ultra high molecular weight) polyethylene bushing that acts as a slip-joint the slip joint having a first end that mounts to the UHMW polyethylene bushing of the tubular body and an opposing end having an eyelet to provide a connection point to a vehicle frame. A two-stage nested coil spring located inside the slip end of the rigid body that rests against the slip joint end when it is inserted into rigid body.

## Claims

### Claim 1

An adjustable floating traction bar comprising:
a rigid body, said rigid body comprising:
a locking end;
a slip end opposing said locking end; and
a weld stop, said weld stop located approximately between a middle of said rigid body and said slip end;
a first coupler, said first coupler having an adjustable end and a coupler end, said adjustable end of said first coupler coupled with said locking end of said rigid body to form a locking adjustment connection, said coupler end of said first coupler configured to provide a connection point to a first portion of a vehicle;
a second coupler, said second coupler having an adjustable end and a coupler end, said adjustable end of said second coupler coupled with said slip end of said rigid body to form a slip joint, said coupler end configured to provide a connection point to a second portion of said vehicle; and
a two-stage nested coil spring, said two-stage nested coil spring comprising a high rate spring and a low rate spring, said two-stage nested coil spring located inside said slip end of said rigid body to rest against said weld stop, said two-stage nested coil spring also rests against the slip joint of said rigid body, the two-stage nested coil spring compresses and provides resistance to said slip joint as said slip joint is forced into said rigid body.

### Claim 2 (depends on 1)

The adjustable floating traction bar of claim 1, further comprising:
an eyelet coupled to said slip joint.

### Claim 3 (depends on 2)

The adjustable floating traction bar of claim 2, wherein said eyelet further comprises:
a spherical joint.

### Claim 4 (depends on 2)

The adjustable floating traction bar of claim 2, wherein said eyelet further comprises:
a polyurethane bushing and a steel sleeve.

### Claim 5 (depends on 2)

The adjustable floating traction bar of claim 2, wherein said eyelet further comprises:
a steel sleeve.

### Claim 6 (depends on 1)

The adjustable floating traction bar of claim 1, wherein said rigid body is a steel tubular body.
