TF508 - Terrafirma 3 Degree Castor Corrected Front Radius Arms - Defender, Discovery 1 and Range Rover Classic

When coil sprung Land Rovers are lifted the castor angle is changed (see diagram). This can lead to vagueness and a lack of self-centring of the steering. Fitting 3 degree castor corrected radius arms re introduces positive castor angle to return the steering to the correct geometry on vehicles lifted 2-3ﾔ (50-75mm), for vehicles lifted more than 2-3ﾔ 6 degree castor corrected radius arms should be used. The TF508 and TF528 radius arms are designed to accept the 44mm wide bushes that fit RRC/D1 from 1986 and Defender from 1994. TF529 radius arms are designed to fit Discovery 2
