Dodge trucks pulling heavy loads or boosted to 400–600HP are at high risk for overdrive burnup due to the stock transmission’s insufficient clutch capacity and fragile OE clutches.
Even small amounts of heat and extra torque will push the thin (.034"), single-sided clutches over the edge, distorting the clutch pack. The fact is, any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burnup inevitable.
Keep hardworking trucks on the road with the Sonnax Smart-Tech® overdrive clutch housing kit 72960-06K. The unique billet aluminum housing holds a physically taller clutch pack and increases OD apply area by 16%. Plus, 2X thicker clutches increase clutch pack steel mass by 28% for unrivaled heat dissipation.
This groundbreaking new kit is the only top-of-the-line upgrade that eliminates clutch problems without relying on valve body/pump modifications or adding the expense of extra components.
Sonnax line pressure booster kit RFE-LB1 is
an improved design over a simple resistor circuit. Featuring an
integrated chip (IC) circuit and a stronger pressure regulator spring,
this new kit delivers 10 psi increase at lower pressure range and 25 psi
increase at higher pressure ranges. Only Sonnax line pressure booster
kits provide progressive pressure increase which gives you smooth
engagements and lower load on the pump at idle, but a greater increase
in pressure as the transmission is worked harder.
This kit is ideal for heavy duty and modified vehicles and even stock transmissions when a little extra pressure is desired.
