C-AJJ3387B

LSD DIFFERENTIAL EVOLUTION 50/90 ROAD

Minispares own Evolution limited slip diff with over 10 years success General spec and design is the same as C-AJJ3387 but has a 55/90 ramp type. The steeper 55 degree acceleration ramp reduces the percentage of torque biased to the wheel with most grip, making this unit less aggressive and more suitable for road use.

If you ever need to take the diff apart you must take the pre-load off with a press and then the 3 screws will come out easily. You will have to remove some metal from gearbox and diff casings, but less than with the old Salisbury.

Evo


1950s design with 1990s engineering and technology - originally done by the inimitable Davc Hirons at Trannex, now under the EVO banner at Mini Spares Centre (www.minispares.com) following their buy-out of all the Mini/Sprite Trannex products some years back now. The only real similarity to the old Salisbury is the 'plate type' design - purely because it gives maximum frictional area, therefore most effective performance.

Historical Article - Nov 1991 - A SERIES EVO L.S.D. Part 2


The cases are machined from steel billets, and all components manufactured to exacting specifications from high grade materials. On the road tests have proven that the bevel gear and plate pack are capable of absorbing 230lh ft of torque in front wheel drive applications. The cross pins are much more substantial than other types.

When most folk talk about limited slip differentials for the Mini, minds immediately turn to the name "Salisbury". Indeed many think that word covers any LSD for the Mini. This, of course, is not so. The Salisbury diff was designed in the 50's at a time when race cars were not sophisticated, tyres were usually cross-ply with limiting grip due to poor compounds, and tracks were more than "a little bumpy".
