The DSPS Engineering ALS (Anti-Lag) Service kits allows your Anti-Lag assembly to be serviced at regular intervals, usually once per season.

DSPS does offer and is able to fully service any of the Anti-Lag valves it has produced, however there are components that would benefit from a regular service, which can easily be performed by the competitor.

Comprising a diaphragm, spring (please specify which spring you require), clamps and valve stem lubricant, as well as replacement K-nuts, AN washers and air fittings, everything is provided to allow for a complete service.

Replacement Viton O-rings and Quad-ring are also provided, as is a new circlip for the Perrins clamp on the air inlet.
