LC300 Series Alpha Suspension Lift Kit Inclusions


Black Hawk Upper Control Arms – JMACX recommends these for any lift in a 300 series. A key feature identified by the FEA testing was the amount of deflection seen between the OE component and the Blackhawk UCA, with the Blackhawk arms being 3 times stiffer than the original equipment, resulting in significant increased handling and feel of your vehicle as the suspension cycles.

Rear Adjustable Panhard – Used to correct axle shift on lifted vehicles. Produced from maximum thickness steel bar, and fitted with ultra tough and flexible rubber bushes. Precise adjustment via a fine pitch thread with locking nut.

Rear Lower Trailing Arms – Heavy duty in car adjustable lower arms saving time and money on alignments and suppling an effective fix to the common pinion angle issue with lifts above 2 inch in 300 Series Landcruisers.

Extended Sway Bar Links – For Non KDSS and Non KDSS (GR Sport) models to Suit your 300 Series with a 2 or 3 inch Lift. Designed to maximise the benefit of Roll Control Adjustable Sway Bars and be used in place of that hard to find OEM link.

Rear Coils – To suit your desired lift height and load weight to get your LC300 where you need it to be.

The manual adjustment Alpha Shocks provide up to 32 levels of adjustment depending on valving in the specifications of the shock. The JMACX Alpha Shocks are easy to install by a competent person and when the vehicle is stationary the adjustment is made easily by hand via turn of the adjuster cap.
