Roller rocker conversions offer the benefits of low friction operation coupled with good rigidity and more accurate valve operation, which combine to release several more bhp.

The standard rocker ratio is 1.5:1. Increasing this to 1.55:1 will give increased valve lift, which combined with a couple of other modifications, such as a decent exhaust and maybe a gas flowed head will give a very noticeable power increase, without the need to install a longer duration camshaft or increase the compression ratio.
If a more radical camshaft is installed or planned, it is necessary to stay close to the original ratio, to avoid excessive valve lift which will inevitably accelerate valve and guide wear.

We recommend a Rocker Oil Feed Kit must be fitted when fitting roller rockers.

Customer Comments
"Yesterday afternoon I ordered 2 bumper mounts for a P38 Range Rover. This morning at 10 o'clock they were delivered to my home. I feel I must congratulate you and your company for service beyond the call of duty. This means my car will be off the road for less than 24 hours. To say I am impressed is an understatement and you have got a customer who will not only use your services again but will recommend you to all my Land Rover friends as well. Thank you once again for outstanding service." Customer Comment
