After Months of testing we are pleased to release the Innovative-RC Losi 5ive Big Bore shocks, Innovative-RC 'Big Bore' shocks are purposely built from the ground up using no stock parts what so ever. Giving a true after market shock with many features over stock shocks...with full spares of every part available.


Based around our proven big bore baja shocks we have kept the large oversized shock body of 20mm which gives plenty of volume for oil backed up by a 8mm high tensile steel shaft that is precision ground for roundness and most important of all that perfect oil seal surface in all running conditions. No large shock shaft would be complete without a full Umbrella/Oil seals to give the best possible oil seal, that is also backup up by other seals to keep all that fine track dirt and sand out of the shock making leaks a thing of the past. So no expensive seal upgrades are needed!!


Each shock Cap Contains a bleeder hole for easy quick assemble and bleeding of the shocks once filled with oil removing all air and excess oil quickly and efficiently. While the shock body has a fully adjustable unlimited potion adjust that screws up and down the length of the shock body giving that ideal shock spring set-up for any track or condition that might come into play.


Each shocks Spring retainer is full housed on the shock shaft & rose joint meaning the spring retainer can no longer come loose meaning no more lost or loose spring retainers. (a slotted version is sold as after market upgrade for those who like fast change spring setups)


Shock body’s also have a ultra fine burnished mirror-like finish giving a tough,work-hardened surface finish as fine as 2 micro-inches (0.05 micrometers) translating to giving a silky smooth operation over the entire shock travel distance.

Shocks come complete with Progressive springs as standard giving you a soft top ride of the shock and a firmer lower spring travel when needed. Giving a nice fine balance over a mixed surface setup.

Shock springs included on IRC Losi Shocks
Front –2.7Wire gauge , 20kg(~44lb) Spring Weight
Rear – 3.2mm Wire gauge, 30kg(~66lb)
*Spring weight is taken in fully compressed state

.:Needed & recommended Parts:.

  • Shock Oil - 57ml (2oz) ~ fills two and half shocks.



.:Oil recommended:.
We find we do get asked this question quite often, please use the bellow as a guide line only, as we can not know your driving style and likes but we find it helps most people get started on there way to a set-up they like, also custom pistons can help in shock rebound rates (see shock parts for blank pistons and other piston types)

Silicone shock oil, recommend, 35-40wt front, 45-50wt rear. (~200CPS - 400CPS front, 280CPS - 650 CPS rear)

For the DBXL, you can run 4x Front Losi 5T shocks all round for a massive improvement over stock.
