LIFT­ING a live axle is sim­ple – taller springs, longer shocks and per­haps a few ad­justable arms to keep the ge­om­e­try this side of hor­ren­dous. But lift­ing an in­de­pen­dent front end can open up a world of hurt if done in­cor­rectly. The is­sue comes down to the an­gle of the drive­shafts and CV joints send­ing power from the chas­sis-mounted diff cen­tre to the wheels – the higher the lift, the greater the an­gle, and the big­ger the chance of fail­ure.

To get around this there are three op­tions. The most sen­si­ble is keep­ing lifts mod­er­ate – most man­u­fac­tur­ers rec­om­mend around the 50mm mark. On the more ex­treme side of things are bracket lifts like Reece is run­ning. In a bracket lift, af­ter­mar­ket cross­mem­bers, spac­ers and brack­ets phys­i­cally push the front sus­pen­sion ar­range­ment away from the chas­sis diff cen­tre, which keeps things rea­son­ably in line with stock ge­om­e­try. Fur­ther to this, some com­pa­nies of­fer long travel kits. Longer con­trol arms and drive­shafts al­low a larger amount of lift for the same CV an­gle, al­though often at the ex­pense of il­le­gally in­creas­ing the track width.
