40mm Lift Kit EFS Shock + Coil Springs for JEEP GRAND CHEROKEE ZJ ZG 3.1L 4.OL

The Product Benefits at A Glance

Low Pressure Nitrogen Gas -To prevent the oil from cavitation (foaming)EFSEnforcershocks

Long Travel Design -To maximise wheel travel when a vehicle is raised and increase articulation

32mm Piston, Twin Tube Construction - Greater control of the spring during the rebound and compression cycles

15mm Quality Hardened Chromed Piston Rod -Increased durability

1.2mm Outer and Inner Wall Thickness -For greater durability and strength

Dynamic Motion Control Technology - Adjusts to different road and off road conditions

High Quality Internal & External Components - To prevent fade under harsh conditions and long life poly bushes for durability

Coil Spring

KING coil spring is designed that the first three laps are 19mm and last four laps are 21mm.And the gap between two laps has been adjusted.To ensure the comfort of normal running,the gap between first three laps is much smaller.The gap between last four laps is bigger,which is designed to keep more stable and better support force when encounters accelerated speed and drastic jolt.

Matched Raised Leaf Springs

Tapered Leaf Ends - To reduce the inter-leaf friction & to improve pressure
distribution in the load bearing area.
Bolt Clip Liners - To reduce noise & friction.
Inter-Leaf Graphite Coating - For further reduction of friction.
Shot Peened & Scragged Tested - To reduce stress & ensure longevity.
Leaf Inserts Pads - For further reduction of friction.
Bolt Clips & Military Wraps - To prevent leaf spread & provide safety

U Bolts Kit

Powder coasted for protection against corrosion & made from quality carbonsteels with rolled threads to increase strength, due to a uniform grain finish.Deep nuts are supplied for safety & strength with flat washers to provide a smooth contact surface area to reduce plate friction.

Urethane Shackle Bushing Kit

Polyurethane Bushes have an elastomer rating of 80 Duro to give improved suppleness & grease channels for increased distribution of lubrication.

Diff Drop Kits

When lifting IFS Vehicles, the Constant Velocity (CV) joints are put on an increased angle. This increased angle of the CV joint during operation can accelerate the wear on the joint, as well as putting additional stress on the CV boots leading to splitting and eventually premature failure of the CV. This wear is accelerated further if larger (wider) wheels and tyres are fitted.The IFS Diff Drop Kits are application specific and supplied complete to get the job done. The bolt on kit corrects the geometry on the front driveshaft and CV's, lowering the front diff by approx. 25mm, thus reducing the angles the CV joints need to operate on, and avoiding the expensive replacements of CV's and boots. Allows the bash plate to be refitted.
