LC80 Rear Adjustable Upper Control Arms (UCA) for lifted Cruisers: MT 4×4 FJ80 Series Land Cruiser/Lexus LX 450 adjustable rear upper links featuring Currie Johnny Joints. One of the biggest benefits of replacing your rear upper control arms on your 100 series Land Cruiser is to correct the pinion angle for proper drive shaft angle. An added benefit as well is the increased flexibility of the axle as it articulations off road for a more stable feel. By adding the Currie Johnny Joint to the link you can easily adjust your axle along with up to 30* of rotation. MT 4×4 rear upper links are made out of 1.25 x.188 DOM tubing, cnc machined to accept Currie 2″ Johnny Joints, poly urethane bushings, 1″ DOM sleeve with .25″ wall support and a grease zirk for maintenance. These links have a limited lifetime warranty on the structure of the link (the tubing and the bushing shell) this does not cover the wear items such as the polyurethane bushings, johnny joint and grease zirks. For the 80 series Land Cruiser we offer these ultra trick, super heavy duty, USA made high quality control arms. When lifting your 80 series the rear control arms angle to the chassis changes, and rotates the pinion angle of the differential. In order to get the driveshaft back into phase the upper control arms are adjusted to set the proper pinion angle. Our 4+ adjustable upper control arms are made from 1-1/4, .250 wall DOM tubing, and on the frame end feature a QA1 Endura rod end with a Teflon/Kevlar, self lubricating, self sealing liner. Rod end body is heat treated Chrome Moly, and the ball is 52100 heat treated, hard chrome plated bearing steel. Increased cross sectional thickness help give this rod end a radial static load rating of 45,000 lbs. Stainless Steel misalignment bushings finish off the adjustable end of the upper control arm . At the axle end of the control arm is a large polyurethane bushing with internal bore grease slots, set with a custom sleeve to help absorb road shocks and vibration instead of transferring into the chassis. Our High Angle control arms allow for resistance free articulation, and adjustment of pinion angle without compromising ride quality in a configuration designed to take heavy punishment and still perform beyond our customers high expectations. Sold in sets. Service parts available separately.
