Method of Vehicle Chassis Elevation

There are currently two wats to lift the raise the chassis:

1. Enlarge tires: replacing larger tires (diameter) can also increase the height of the chassis, but there are some drawbacks. Firstly, the dynamic performance of the vehicle will have a significant impact, so the tire increase (diameter) should be within a reasonable range. Secondly, due to the location restrictions of mudguards, fenders, etc., the space for raising the height of the kit is limited. Thirdly, if an enlarged tire (diameter) is installed, the vehicle suspension must be lifted.

2. Modified suspension: The suspension system is very complicated to explain. Generally speaking, it can be divided into front suspension elevation and rear suspension elevation. They can be divided into "soft bridge elevation (independent suspension system elevation)" and "hard bridge elevation (non- independent suspension system elevation)." In most off-road vehicles' suspension system configuration, the front is soft, and the rear is hard. The lifting by leveling lift kit is not merely to raise a few inches but also to make the suspension system perform better. 

According to the different vehicles, I will give you a method to calculate the maximum height of the car through the leveling lift kit:

1. Lift the car into the air and measure the distance from the tire's bottom to the wheel eyebrow as A.

2. The distance between the bottom of the tire and the wheel eyebrow is B when the vehicle is stationary on the road.

3. Take the original car's suspension protection stroke of 5CM as an example, then the limit height of increase = A-B-5CM

Take the Isuzu MUX as an example; the limit height that it can raise through the Isuzu MUX lift kit is 96CM(A)-86CM(B)-5CM (protection stroke)=5CM (limit raising height). 

Isuzu lift kits will be used here.

According to previous practical experience, the probability of replacement of parts for non-load-bearing off-road vehicles two-inches lifting:

Shock absorber: 100%

Spring: 90% (the spring part is a torsion bar spring, which can not be replaced)

Small connecting rod: 10% (after being lifted, it can not be replaced if the stroke limit is not reached)

Thrust rod: 80% (after raising, the stroke limit can not be replaced)

Tie rod: 5% (after being lifted, it can not be replaced if the stroke limit is not reached)

Oil pipe: 5% (after being lifted, it can not be replaced if the stroke limit is not reached)

Upper and lower limit (buffer block): 15% (after rising, the stroke limit can not be replaced)
