Triumph TR3- TR6 Quaife Limited Slip LSD Axle Diff Assembly Built to Order. Suitable for road, trackday or motorsport use, I offer fully overhauled Triumph IRS or Live beam axles, complete with a brand new UK-made Quaife limited-slip unit & your choice of ratio. Default ratio is the standard PI at 3.45:1, whilst 3.7:1, 3.9:1, 4.1:1, 4.3:1, & 4.55:1 can all be supplied, subject to availability & added cost for ratios higher than 3.7:1. New bearings & uprated seals are fitted, & the IRS front mounting plate can be reinforced if required- (recommended for motorsport use). I have built a large number of Triumph axles over the last thirty-odd years & know how to keep them in one piece, even when transmitting 250 lb of torque & 250+ BHP on the racetrack. I require a core unit, with undamaged front & rear mounts, to work from, but can supply on an outright basis from time to time, subject to availability of usable core. The advertised price reflects the fitment of quality Japanese bearings & an unworn OEM 3.45 or 3.7 crownwheel/pinion pair. Please contact me for more detailed costing to include Timken bearings & brand new CW&P sets. Please ask any & all questions before committing!
